This large package contains the most important classes and interfaces of Swing. Swing is a core part of Java 1.2 and is also available as a standard extension to Java 1.1. The GUI component classes are at the heart of Swing. These classes have names that begin with the letter J. Figure 23-1 shows the hierarchy of Swing components in javax.swing. Note that this diagram does not show the fact that all the Swing components implement javax.accessibility.Accessible; see the individual class synopses for this information.
Most Swing components rely on a model object to hold their state information. Various interfaces define the methods that these state objects must implement, and various abstract and concrete classes implement these interfaces. These model interfaces and classes are recognizable by the word "Model" in their names. Figure 23-2 shows the model objects and layout managers in javax.swing.
Classes with the word "Manager" in their names typically manage some important part of the Swing user-interface or application environment. Other important classes and interfaces defined by this package include: Action, Icon, KeyStroke, Timer, and SwingUtilities. Figure 23-3 shows the rest of the classes and interfaces in javax.swing.
All Swing components are accessible, which means that they implement the javax.accessiblity.Accessible interface and define getAccessibleContext() methods. This method returns a javax.accessibility.AccessibleContext object that provides support to accessibility tools, such as screen readers for the vision impaired. Each accessible component has its own specific subclass of AccessibleContext, which is typically defined as a protected inner class of the component. These AccessibleContext inner classes have been omitted from this chapter and from Figure 23-1 because they contain little useful information and they detract from other, more important classes. Practically everything you need to know about an AccessibleContext subclass can be found in the single-line inner class synopsis that appears in the containing class, the accessible flag of the containing class, and in Chapter 22, "The javax.accessibility Package".
See Chapter 2, "Swing and AWTArchitecture", for an overview of GUI programming in Java, and see Chapter 3, "Swing Programming Topics", for detailed explanations of many important Swing components and capabilities.
| AbstractAction | Java 1.2 | |
|
||
| javax.swing | cloneable serializable | |
This class implements all the methods of the Action interface except for the crucial actionPerformed() method that provides the substance of the action. Subclassing AbstractAction is one of the easiest ways to define Action objects for your application. Note the one- and two-argument constructors. These constructors automatically define name and icon attributes for the action and are simpler than using putValue().

| AbstractButton | Java 1.2 | |
|
||
| javax.swing | serializable swing component | |
This class serves as the superclass for Swing components with buttonlike behavior. Because it is a general-purpose class, it defines a large number of properties. Like Swing labels, Swing buttons can display text and/or an icon, and several properties specify the relative positioning of the text and icon. (See JLabel for details on these positioning properties.) Swing buttons can display different icons when in different states. In addition to the default icon, AbstractButton has properties that specify icons to be displayed when the button is pressed, selected, disabled, disabled and selected, rolled over, and rolled over and selected. If the rolloverIcon property is specified and if the rolloverEnabled property is true, the rolloverIcon is displayed when the mouse is over the button.
By default, an AbstractButton displays a single line of text in a single font. However, as of Swing 1.1.1 and Java 1.2.2, if the text property begins with "<html>", the button text is formatted as HTML and may contain multiple fonts and multiple lines.
A Swing button may be enabled and disabled with setEnabled(). Disabled buttons are typically displayed with grayed-out graphics, although some other disabled icon can also be specified. A mnemonic can be specified with setMnemonic(). This causes the mnemonic character to be underlined in the button's text and allows the button to be operated via the keyboard.
Swing buttons generate three types of events. A java.awt.event.ActionEvent is generated when any button is pushed. A java.awt.event.ItemEvent is generated when a toggle-type button is selected or deselected. And a javax.swing.event.ChangeEvent is generated when the button's internal state changes--for example, when the mouse pointer enters the button or when the user arms the button by pressing the mouse button.

| AbstractButton.ButtonChangeListener | Java 1.2 | |
|
||
| javax.swing | serializable | |
This protected inner class is a simple Serializable implementation of javax.swing. event.ChangeListener that AbstractButton uses internally to receive change notifications from its ButtonModel. Application-level code never needs to use this class.

| AbstractListModel | Java 1.2 | |
|
||
| javax.swing | serializable model | |
This abstract class provides a partial implementation of the ListModel interface. Subclassing AbstractListModel is usually easier than implementing ListModel from scratch. Note, however, that the DefaultListModel class is a usually an adequate ListModel implementation, so you shouldn't need to subclass AbstractListModel very often. Furthermore, the JList component provides convenience methods that often make it unnecessary to work with any kind of ListModel at all.

| Action | Java 1.2 | |
|
||
| javax.swing | event listener | |
An action is a single piece of application functionality, such as saving a file or printing a document. The actions performed by an application may be made available to the user in several different ways: in a pulldown or popup menu, in a toolbar, and from a keyboard binding, for example.
The Action interface extends java.awt.event.ActionListener and adds the ability to enable or disable the action. If an editor contains an empty document, its print action probably should not be enabled, for example. setEnabled() specifies whether the action is enabled. When an action is enabled or disabled, this change is broadcast by a java.beans.PropertyChangeEvent.
The Action interface also defines methods that associate attributes with an action. The putValue() method maps an arbitrary attribute name to an arbitrary attribute value. The getValue() method queries an attribute value. The constants defined by the Action interface specify predefined names for commonly used attributes. NAME and SMALL_ICON are the most commonly used. Finally, the actionPerformed() method, inherited from ActionListener, is responsible for performing the action.
JMenu, JPopupMenu, and JToolBar define methods that allow Action objects to be added to them. These methods query the action for its name and an icon that represents the action and use this information to present the action to the user. If the action is enabled, the component allows the user to invoke it. The JTextComponent and Keymap classes from the javax.swing.text package additionally provide techniques for mapping keystrokes to Action objects.
AbstractAction provides a useful starting point for defining your own Action classes.

| BorderFactory | Java 1.2 | |

The static methods of this class return various types of Border objects. These methods may return previously created shared objects, making their use more memory-efficient than creating unshared Border objects with the new operator. See the various classes of the javax.swing.border package for more information on the types of borders supported by Swing.

| BoundedRangeModel | Java 1.2 | |
|
||
| javax.swing | model | |
This interface defines the data model used by the JScrollBar, JSlider, and JProgressBar components. The model is defined by four integer properties that obey the following relationship:
minimum <= value <= value+extent <= maximum
The value property specifies the value currently displayed by the component. It must be between the values specified by the minimum and maximum properties. The extent property specifies the amount of data displayed. For JScrollBar components, this property specifies the size of the scrollbar thumb, or knob. Note the convenience method setRangeProperties() that sets all properties of the model at once.
When any value changes, interested listeners are notified with a javax.swing.event.ChangeEvent. One additional property defined by this interface is valueIsAdjusting. If this property is true, it means that a series of rapid property changes (such as those caused when the user drags the scrollbar) is in progress. This property is false for the last change in the series, so listeners can therefore choose to ignore transient changes that have this property set to true.
DefaultBoundedRangeModel is an implementation of this interface appropriate for most uses.

| Box | Java 1.2 | |
|
||
| javax.swing | serializable accessible swing component | |
This class is a container that uses the BoxLayout layout manager to arrange its children in a row or a column. Pass one of the constants BoxLayout.X_AXIS or BoxLayout.Y_AXIS to the constructor to create a horizontal or vertical box or use the static methods createHorizontalBox() and createVerticalBox(). A horizontal box attempts to lay out its children from left to right, one next to the other, at their preferred widths and tries to make each child as tall as the tallest child. A vertical box does the opposite: it lays out its children from top to bottom, trying both to maintain the preferred height of each child and to make all children as wide as the widest child.
The arrangement of children in a Box is often improved with the use of struts and glue: invisible components that exist only to improve the appearance of a layout. A horizontal strut has 0 height and has a specified value as its minimum, preferred, and maximum width. A vertical strut has 0 width and a fixed height. Struts are useful for inserting fixed amounts of space between components in a Box. Use createHorizontalStrut() and createVerticalStrut() to create struts.
Glue is a component with a preferred width or height of 0 but with an infinite maximum width or height. Glue is used to specify where extra space in a layout should go. For example, if you have three fixed-sized JButton components in a row that is wider than the sum of the button widths, placing glue between them forces them to be evenly spaced. Use createHorizontalGlue() and createVerticalGlue() to create glue components.

| CellEditor | Java 1.2 | |
|
||
| javax.swing | ||
This interface defines general methods that must be implemented by any cell editor object. isCellEditable() should return true if the cell is editable and if the specified event is an appropriate event to trigger an edit. (For example, some programs might require a double-click to edit a cell.) shouldSelectCell() should return true if the given event should cause the cell to become selected or false otherwise. However, this is only a minor secondary purpose of the method. Despite its name, the primary purpose of shouldSelectCell() is to cause the cell editor to begin editing the cell. The editor can use the specified event to set the initial state (e.g., cursor position) of the editor.
getCellEditorValue() returns the value being edited. cancelCellEditing() cancels an edit. stopCellEditing() instructs the editor to stop editing and accept a partially edited value. An editor may return false if it cannot accept the current value (because the partial value is not valid, for example). If the editor stops or cancels editing itself, it sends a javax.swing.event.ChangeEvent to any registered javax.swing.event.CellEditorListener objects.
javax.swing.table.TableCellEditor and javax.swing.tree.TreeCellEditor are table- and tree-specific cell editor interfaces; DefaultCellEditor is an implementation of both those interfaces.

| ComboBoxModel | Java 1.2 | |
|

| javax.swing | model | |
This interface defines the basic model used by the JComboBox component. The JComboBox allows the user to select a value from a list or type a value directly. Therefore, ComboBoxModel extends ListModel to add support for a selected item, in addition to the list of items that ListModel already supports. See also MutableComboBoxModel and DefaultComboBoxModel.

| FocusManager | Java 1.2 | |
|
||
| javax.swing | ||
This abstract class defines three instance methods that must be implemented by an object that wants to manage keyboard focus for an application. It also defines static methods that manipulate the installed focus manager. Applications that mix AWT components with Swing components should call disableSwingFocusManager() to disable Swing's focus management and rely on the AWT focus manager. Call setCurrentManager() to replace the current focus manager with a custom manager of your own.

| GrayFilter | Java 1.2 | |
|
||
| javax.swing | cloneable | |
This class is a java.awt.image.ImageFilter that converts a color image to a grayscale image, suitable for use as an icon that represents a disabled action or an unavailable option. In addition to the usual ImageFilter methods, GrayFilter provides the static createDisabledImage() method, which is all that most applications ever need to use. The AbstractButton and JLabel classes use GrayFilter to automatically create a grayscale version of an image, if no disabled image is explicitly provided.

| ImageIcon | Java 1.2 | |
|
||
| javax.swing | serializable | |
This class is an implementation of the Icon interface that uses an Image to draw the icon. The various constructors allow the image to be specified as an Image object, as a URL, as a file name, or as an array of binary data. Every ImageIcon can have a short textual description that may be used for accessibility (e.g., to describe the icon to a blind user).

| JApplet | Java 1.2 | |
|
||
| javax.swing | serializable accessible swing component bean container | |
This class is the Swing version of its superclass, java.applet.Applet. It creates a JRootPane as its sole child, and, like JFrame, JDialog, and similar classes, it implements RootPaneContainer. Calling add() or setLayout() on a JApplet raises an exception. Instead, call getContentPane() to obtain a reference to an internal container on which you can call add() and setLayout(). The default layout manager for this content pane is a BorderLayout. Because JApplet is a RootPaneContainer, it can display a Swing menubar. Use setJMenuBar() and getJMenuBar().

| JButton | Java 1.2 | |
|
||
| javax.swing | serializable accessible(action,value) swing component | |
This class implements a push button. The constructors allow a textual label and/or an icon to be specified for the button. isDefaultButton() checks to see if the button is the default button registered with the setDefaultButton() method of JRootPane. A JButton generates a java.awt.event.ActionEvent when clicked. Most of the interesting properties and methods of JButton are implemented by AbstractButton. The default JButton model is DefaultButtonModel.

| JCheckBox | Java 1.2 | |
|
||
| javax.swing | serializable accessible(action,value) swing component | |
This class implements a check button: a toggle button with default graphics that indicate that the button does not have mutually exclusive behavior. Because JCheckBox supplies its own default and selected icons, you typically do not use the constructors that take Icon arguments. The initial selection state of a JCheckBox can be specified in the call to the constructor. The state can also be set with setSelected() and queried with isSelected(). Use JRadioButton and ButtonGroup instead of JCheckBox if you want to display a set of mutually exclusive choices. The default JCheckBox model is JToggleButton.ToggleButtonModel. Note that java.awt.Checkbox is spelled with a lowercase b, while JCheckBox has an uppercase B.

| JCheckBoxMenuItem | Java 1.2 | |
|
||
| javax.swing | serializable accessible(action,value) swing component | |
This class implements a check button that appears within a pulldown or popup menu. Its use is similar to that of JCheckBox. Use isSelected() to query the selection state of the menu item and setSelected() to select or deselect the item. For menu items with mutually-exclusive selection behavior, use JRadioButtonMenuItem instead. The default JCheckBoxMenuItem model is JToggleButton.ToggleButtonModel.

| JColorChooser | Java 1.2 | |
|
||
| javax.swing | serializable accessible swing component | |
This component allows the user to select a color. The easiest way to use it is to call the static showDialog() method, specifying a parent Component for the dialog, a title, and an initial default color. The method creates a JColorChooser in a modal JDialog and blocks until the user dismisses the dialog. If the user dismisses the dialog with the OK button, the method returns the selected color. If the user dismisses the dialog with the Cancel button, or in any other way, showDialog() returns null.
If you need more control over the color selection dialog, you can call createDialog(). This static method creates a JDialog that contains the JColorChooser component you specify. It allows you to specify java.awt.event.ActionListener objects to respond to the OK and Cancel buttons. It does not automatically display the dialog for you, nor does it wait for the user to make a selection.
You can also create and manipulate a JColorChooser on your own, placing it in any dialog or other container. You can register a java.beans.PropertyChangeListener object (with the inherited addPropertyChangeListener() method) to receive notification when the color property changes.
JColorChooser is highly customizable. You can specify how colors are selected by specifying a custom subclass of javax.swing.colorchooser.AbstractColorChooserPanel to addChooserPanel() or setChooserPanels(). And you can customize the way that colors are previewed by specifying an appropriate component to setPreviewPanel(). The default JColorChooser model is a javax.swing.colorchooser.DefaultColorSelectionModel.

| JComboBox | Java 1.2 | |
|
||
| javax.swing | serializable accessible(action) swing component | |
This class implements a combo box: a combination of a popup list of selectable items and an item editor that displays the selected value and, optionally, allows the user to enter an item that does not appear on the list. The editor is usually a text field, but a JComboBox can be configured to use another component as its ComboBoxEditor.
Typically, you create a JComboBox by passing a Vector or array of objects to a constructor. Alternatively, you can create an empty JComboBox and add items to it with addItem(). You can set and query the selection with setSelectedItem(), setSelectedIndex(), getSelectedItem(), and getSelectedIndex(). The JComboBox generates a java.awt.event.ActionEvent when the selection changes. The default JComboBox model is a private implementation of the ComboBoxModel interface. If you want to implement keyboard shortcuts for a JComboBox, implement the JComboBox.KeySelectionManager interface and pass an instance to the setKeySelectionManager() method.

JComponent is the root of the Swing component hierarchy. It inherits the properties and methods of java.awt.Component and java.awt.Container, including such commonly used properties as foreground, background, font, cursor, enabled, and visible.
In addition to these inherited properties, JComponent defines a number of new properties that are commonly used. The border property specifies a Border object that displays a border (or a blank space) around the component. doubleBuffered specifies whether the JComponent should automatically use double-buffering to reduce flickering during redraws. opaque specifies whether the component draws its background or lets its parent' background show through. toolTipText specifies the text to appear in a tooltip when the mouse pointer lingers over the component.
In addition to the standard get/set property accessor methods, JComponent also defines getClientProperty() and putClientProperty(). In effect, every JComponent maintains a hashtable that maps arbitrary property names to values. You can use this to associate arbitrary data with any Swing component. It is also occasionally used to specify properties that are specific to certain look-and-feels.

| JDialog | Java 1.2 | |
|
||
| javax.swing | serializable accessible swing component bean container | |
This class is used to display Swing dialog boxes. Every JDialog component has an automatically created JRootPane as its single child. Components must not be added directly to the JDialog component. Instead, they should be added to the container returned by getContentPane() method. The default layout manager of this content pane is java.awt.BorderLayout. Unlike its java.awt.Dialog superclass, JDialog can display a menubar. Specify one with setJMenuBar(). setDefaultCloseOperation() specifies how the JDialog should behave when the user attempts to close it. The argument should be one of the constants defined by the WindowConstants interface. The default is HIDE_ON_CLOSE. JDialog uses a native window. Use JInternalFrame for lightweight dialogs.

| JEditorPane | Java 1.2 | |
|
||
| javax.swing | serializable accessible(text,hypertext) swing component | |
This class is a subclass of javax.swing.text.JTextComponent that can be easily configured to display and edit different formatted-text content types using a javax.swing.text.EditorKit object. To configure a JEditorPane, call setEditorKit() to specify an appropriate editor kit for the desired content type. Alternatively, use the static registerEditorKitForContentType() to register a mapping between content types and their corresponding editor kits and then call setContentType(). With such a mapping in place, you may also use setPage() to specify a URL to be displayed. The JEditorPane determines the content type of the URL, installs an appropriate EditorKit, and loads the contents of the URL into the JEditorPane. Swing comes with two predefined EditorKit subclasses: javax.swing.text.html.HTMLEditorKit and javax.swing.text.rtf.RTFEditorKit.

| JFileChooser | Java 1.2 | |
|
||
| javax.swing | serializable accessible swing component | |
This component allows the user to select a file. After creating a JFileChooser component, and setting any desired properties, the easiest way to use it is to call showOpenDialog() or showSaveDialog(). These methods display the JFileChooser in a modal dialog box, using the component you specify as its parent. They also customize the "Okay" button to read Open or Save (or locale-appropriate equivalents). You can also call showDialog() and explicitly specify the text to appear in the "Okay" button. The methods return APPROVE_OPTION if the user selects a file and clicks the Save or Open button. They return CANCEL_OPTION if the user clicks the Cancel button or otherwise dismisses the dialog. They return ERROR_OPTION if some sort of error or exception occurs during file selection. When the return value is APPROVE_OPTION, you can call getSelectedFile() to obtain a File object that represents the file the user selected.
Other commonly used JFileChooser properties are currentDirectory, which specifies the initial or most recently selected directory displayed by the JFileChooser, and fileSelectionMode, which specifies whether the JFileChooser should allow the user to choose a file, a directory, or either. The legal values for the fileSelectionMode property are FILES_ONLY, DIRECTORIES_ONLY, and FILES_AND_DIRECTORIES.
You can selectively filter files, so that only certain choices are displayed to the user, by passing a javax.swing.filechooser.FileFilter object to setFileFilter(). This allows you, for example, to tell the JFileChooser to display only files that have an extension of .htm or .html. The default FileFilter is one that display all files. You can obtain an instance of it by calling getAcceptAllFileFilter(). You can provide a set of file filters for the user to choose from by setting the choosableFileFilters property to an array of FileFilter objects.
In addition to file filters, JFileChooser provides another powerful way to customize the file selection dialog. The accessory property allows you to specify a JComponent file selection accessory to be displayed within the JFileChooser. Such accessories are typically used as file previewers. For example, you might write an accessory to display a thumbnail version of a selected image file. The accessory object must register a PropertyChangeListener on the JFileChooser, so that it can receive notification of changes in the selectedFile property.

| JFrame | Java 1.2 | |
|
||
| javax.swing | serializable accessible swing component bean container | |
This class is used to display the main window (or windows) of a Swing application. Every JFrame has a single automatically created JRootPane child. You should not add children directly to the JFrame, but instead call getContentPane() and add children to the container returned by that method. Similarly, if you set a layout manager, you should do so on the container returned by getContentPane(). The default layout manager for this container is an instance of java.awt.BorderLayout.
The JFrame has two other features of interest. First, setJMenuBar() automatically places a specified menubar at the top of the window, leaving the content pane free for other application content. Second, setDefaultCloseOperation() specifies how the window should respond when the user attempts to close it (e.g., by typing Alt-F4 in Windows). The argument to this method should be one of the constants defined by javax.swing.WindowConstants. The default is HIDE_ON_CLOSE. In addition to these features, JFrame also inherits useful methods from java.awt.Frame, including setCursor(), setIconImage(), setResizable(), and setTitle().
JFrame uses a heavyweight native window. To create a lightweight window that appears entirely within the confines of a containing window, you can use JInternalFrame.

| JInternalFrame | Java 1.2 | |
|
||
| javax.swing | serializable accessible(value) swing component bean container | |
This class is a lightweight Swing component that simulates a heavyweight native window, complete with titlebar and other window decorations appropriate to the installed look-and-feel. Because it is a lightweight component, with no native window of its own, a JInternalFrame is constrained to stay within the bounds of its container. This container is typically a JDesktopPane. Within a JDesktopPane, a JInternalFrame can be moved, resized, iconified, and maximized, much like a JFrame can be.
JInternalFrame is like JFrame in many ways. A JInternalFrame has a JRootPane as its only child. Components should not be added directly to a JInternalFrame, but rather to the container returned by getContentPane(). setJMenuBar() specifies a menubar for the lightweight window, and setDefaultCloseOperation() specifies how it should respond when the user closes it. See JFrame for more on these two methods.
setTitle() sets the title displayed in the internal frame's titlebar. setFrameIcon() specifies a small image to be displayed in the titlebar and possibly also in the iconified representation of the JInternalFrame. setIconifiable() specifies whether the user is allowed to iconify the window, setIcon() actually iconifies or deiconifies the window, and isIcon() queries whether the window is currently iconified. setDesktopIcon() specifies the internal JInternalFrame.JDesktopIcon object used to represent the iconified version of the JInternalFrame. This last method should not be used by application-level code.
Similarly, setMaximizable() specifies whether the user can maximize the window, and setMaximum() maximizes the window. setResizable() specifies whether the window can be resized. setSelected() selects or deselects the window, and toFront() and toBack() move the window to the top and bottom of the stacking order relative to other JInternalFrame windows. Finally, as with all components, setVisible() makes the window visible or invisible.

| JLabel | Java 1.2 | |
|
||
| javax.swing | serializable accessible swing component | |
This class displays a short string of text and/or an Icon. JLabel is a display-only component with no behavior, so the displayed text and/or icon does not respond to any input events. JLabel does not maintain any state and therefore does not use a model. By default, a JLabel displays a single line of text in a single font. However, as of Swing 1.1.1 and Java 1.2.2, if the text property begins with "<html>", the label is formatted as HTML text and may contain multiple fonts and multiple lines.
The icon, text, and font properties need no explanation. disabledIcon specifies an alternate icon to display when the JLabel is disabled. By default, a grayscale version of the regular icon is used. horizontalAlignment and verticalAlignment specify the justification of the label, and horizontalTextPosition and verticalTextPosition specify the position of the text relative to the icon. Each of these properties should be set to one of the LEFT, CENTER, RIGHT, TOP, or BOTTOM constants defined by the SwingConstants interface. The iconTextGap property specifies the number of pixels between the text and the icon.
Although JLabel does not have any behavior of its own, it can display a mnemonic character. If the displayedMnemonic property is set, the specified character is underlined in the label. If the labelFor property refers to another component, the JLabel requests keyboard focus for that component when the mnemonic is used. This is useful for labeling JTextField components, for example.

| JLayeredPane | Java 1.2 | |
|
||
| javax.swing | serializable accessible swing component | |
This class is a Swing container that layers its children according to a specified stacking order. When you add a child to a JLayeredPane, you specify an Integer as the constraints argument to the add() methods. This Integer object specifies the layer number for the child, where higher numbers are nearer the top of the stack. JLayeredPane defines a number of _LAYER constants as predefined layers. The layer of a child can also be set with setLayer(). If multiple children are in the same layer, their relative stacking order is determined by their insertion order. This position within a layer can be modified with setPosition(), moveToFront(), and moveToBack(). JLayeredPane is typically used without a layout manager; children have their size and position explicitly set.
All JFrame, JDialog, JApplet, and JInternalFrame objects contain a JRootPane which, in turn, contains a JLayeredPane. This internal JLayeredPane is used to correctly layer lightweight menus, dialogs, floating palettes, internal frames, and so forth.

| JList | Java 1.2 | |
|
||
| javax.swing | serializable accessible(selection) swing component | |
This class displays a list of items (typically strings) and allows the user to select one or more of them. The objects to be displayed are stored in a ListModel object. Two JList constructors allow list items to be specified as a static array or Vector of objects, however. For a dynamic list of elements, you may want to use your own instance of DefaultListModel, which maintains a Vector-like list of objects. By default, JList displays lists of strings. To display other types of list items, define an appropriate ListCellRenderer class and pass an instance of it to setCellRenderer().
The selection state of the JList is maintained by a ListSelectionModel object. By default, JList uses a DefaultListSelectionModel object. Application programmers rarely need to work with the ListSelectionModel directly because JList provides a number of methods to query and set the selection state. setSelectionMode() specifies the types of selections allowed by the JList. Its argument should be one of the three constants defined by ListSelectionModel. SINGLE_SELECTION allows only a single item to be selected, while SINGLE_INTERVAL_SELECTION allows multiple items in a single contiguous block to be selected and MULTIPLE_INTERVAL_SELECTION allows any number of items, contiguous or not, to be selected.
JList generates a javax.swing.event.ListSelectionEvent when the selection state changes and sends it to the valueChanged() methods of any registered javax.swing.event.ListSelectionListener objects.

| JMenu | Java 1.2 | |
|
||
| javax.swing | serializable accessible(action,selection,value) swing component | |
This class implements a pulldown menu in a menubar or a pull-right menu nested within another menu. As a subclass of JMenuItem, JMenu is effectively a menu button with an associated JPopupMenu that appears when the button is activated. Menu items can be added to a JMenu with the add(), insert(), addSeparator(), and insertSeparator() methods. Note that you can add String and Action objects in addition to regular JMenuItem objects. In these cases, an appropriate JMenuItem is automatically created for the String or Action. JMenu generates a javax.swing.event.MenuEvent when it is selected and when its menu is popped up or down. The default JMenu model is DefaultButtonModel.

| JMenuBar | Java 1.2 | |
|
||
| javax.swing | serializable accessible(selection) swing component | |
This class implements a menu bar. JMenu objects are placed in a JMenuBar with the add() method and can be removed with the remove() methods. A Help menu should be singled out for special treatment (typically by placing it at the right-hand edge of the menu bar) with setHelpMenu(). JMenuBar uses a SingleSelectionModel object to keep track of which of its JMenuItem children (if any) is currently selected. By default, JMenuBar uses a DefaultSingleSelectionModel model object.
In AWT, the MenuBar class is not a Component. In Swing, JMenuBar is a JComponent and can be laid out in an application like any other component. Note, however, that JFrame, JDialog, JApplet, and JInternalFrame all have setJMenuBar() methods that automatically position a JMenuBar at the top of the window. This is the easiest and most common way to lay out a menu bar.

| JMenuItem | Java 1.2 | |
|
||
| javax.swing | serializable accessible(action,value) swing component | |
This class implements an item in a pulldown or popup menu. As a subclass of AbstractButton, it shares most of the properties of JButton. One new feature is that it allows an accelerator to be specified. An accelerator is a keyboard binding for the menu item. Like all Swing buttons, JMenuItem also supports a mnemonic. Accelerators differ from mnemonics in two important ways, however. First, accelerators can be used at any time, while menu item mnemonics can be used only when the menu that contains them is displayed. Second, accelerators are specified with a KeyStroke object, rather than a simple character. This allows complex bindings that include function keys and arbitrary modifier keys.
In addition to its AbstractButton functionality, JMenuItem also implements the MenuElement interface. The default JMenuItem model is DefaultButtonModel, and the UI delegate class is MenuItemUI.

| JOptionPane | Java 1.2 | |
|
||
| javax.swing | serializable accessible swing component bean container | |
This component is used to display various types of simple dialog boxes to the user (yes, its name is misleading). It is almost always used through one of the showXXXDialog() static methods. The fact that there are more than 20 of these methods demonstrates the highly-configurable nature of this class. The showInternalXXXDialog() methods display dialogs in lightweight JInternalFrame windows. The other static methods display methods in heavyweight JDialog windows.
You can create and display a simple message dialog with showMessageDialog() and showInternalMessageDialog(). These methods display a dialog box that contains the specified message, an optional icon, and an Okay button that dismisses the dialog. The dialog is modal, meaning it blocks, returning only when the user has dismissed the dialog. The parentComponent argument specifies the component that serves as the parent of the dialog (the dialog typically pops up over this component), while title specifies a string to appear in the titlebar of the dialog. The message argument is more complex. It is declared as an Object. You typically pass a String value, which is automatically displayed in a JLabel. However, you can also specify an Icon, which is also displayed in a JLabel, or any JComponent, which is displayed as is. Furthermore, instead of specifying a single message object, you can specify an array of objects that contains any combination of strings, icons, and components. The messageType argument must be one of the constants WARNING_MESSAGE, QUESTION_MESSAGE, INFO_MESSAGE, ERROR_MESSAGE, or PLAIN_MESSAGE. These constants specify the basic type of message you are displaying. The current look-and-feel may customize the appearance of the dialog based on this value. Typically, the customization is limited to the display of one of a standard set of icons. If you'd like to override the default icon for the dialog, you can also explicitly specify an icon argument.
The showConfirmDialog() and showInternalConfirmDialog() methods are much like showMessageDialog() and showInternalMessageDialog(), except that they ask the user to make a choice and provide several push buttons that represent the options available to the user. (It is the options represented by these buttons from which the name JOptionPane derives.) For example, showConfirmDialog() can be used to display a dialog that asks "Do you really want to quit?" and allows the user to respond by pushing either a Yes button or a No button. The parentComponent, title, message, messageType, and icon arguments to these methods are the same as for the message dialogs. The confirm dialogs add an optionType argument and a return value. optionType specifies which buttons should appear in the dialog. It should be one of the constants DEFAULT_OPTION, YES_NO_OPTION, YES_NO_CANCEL_OPTION, or OK_CANCEL_OPTION. DEFAULT_OPTION provides a single Okay button; the others provide buttons as indicated by their names. Like the message dialogs, the confirm dialogs are modal, and the static methods that display them block until the user has dismissed the dialog. Since confirm dialogs present choices to the user, they have return values that indicate the choice the user selected. This return value is one of the constants OK_OPTION, CANCEL_OPTION, YES_OPTION, NO_OPTION, or CLOSED_OPTION. This last value indicates that the user closed the dialog window without selecting any of the available buttons; typically, it should be treated as a CANCEL_OPTION response.
showOptionDialog() and showInternalOptionDialog() are generalizations of the confirm dialog. They take an options argument, which specifies what buttons to display in the dialog box, and an initialValue argument, which specifies which of these buttons should be the default button. The options argument is an array of objects. Typically, you specify string values that the JOptionPane displays in JButton components. You can provide arbitrary components in the options array, but if you do so, you must arrange for each component to update the state of the JOptionPane by calling its setValue() method when selected.
The final category of dialogs are the input dialogs, created with showInputDialog() and showInternalInputDialog(). Most versions of these methods take the same arguments as the message dialogs. However, in addition to displaying a message, they also contain a JTextField in which the user can enter whatever input value is requested. These dialogs are modal, and the methods that display them block until the user has dismissed the dialog. If the user dismisses the dialog with the Okay button, the methods return the user's input as a String. If the user dismisses the dialog with the Cancel button, these methods return null. One version of both showInputDialog() and showInternalInputDialog() are different. These methods take additional selectionValues and initialSelectionValue arguments. Instead of asking the user to enter a string, they ask the user to choose among the values contained in the selectionValues array (presenting initialSelectionValue as the default value). The display of these values is left to the current look-and-feel, although they are typically displayed using a JComboBox or JList component. The selectionValues array typically contains strings, but it may also contain Icon objects or other objects that can be meaningfully displayed by JList and JComboBox components. When you pass an array of selectionValues to showInputDialog() or showInternalInputDialog(), the return value is the value the user has chosen or null, if the user selected the Cancel button.
Instead of using one of the static methods to display a JOptionPane dialog, you can also create a JOptionPane component, set properties as desired, and then create a dialog to contain it by calling the createDialog() or createInternalFrame() instance method.

| JPasswordField | Java 1.2 | |
|
||
| javax.swing | serializable accessible(text) swing component | |
This JTextField subclass is designed for entering passwords and other sensitive data. It does not display the characters of the entered text, preventing it from being read by onlookers. Use setEchoChar() to specify the character that should appear (e.g., an asterisk) in place of the characters entered by the user.
JPasswordField overrides and deprecates the getText() method of JTextField. Instead, use getPassword() to obtain the user's input. This method returns an array of characters instead of an immutable String object. This means that after you use the password, you can set the elements of the array to 0 for additional security.

| JPopupMenu | Java 1.2 | |
|
||
| javax.swing | serializable accessible swing component | |
This component displays a menu of choices in a popup window. It is used both for standalone popup menus that are posted when the user clicks the right mouse button and for the pulldown and pull-right menus that appear when the user selects a JMenu component. JPopupMenu uses a SingleSelectionModel to maintain its selection state.
After you create a JPopupMenu object, you can add items to it with the add() and addSeparator() methods. The java.awt.event.ActionListener of a menu item is notified when that item is selected. After adding items to the menu, you can pop it up at a specified location with the show() method. This is usually done only after calling the isPopupTrigger() method of a java.awt.event.MouseEvent object. The menu automatically pops itself down when the user selects an item or stops interacting with it. Call setLightWeightPopupEnabled() to specify whether the popup should use a lightweight window or a heavyweight native window. Call the static setDefaultLightWeightPopupEnabled() to specify a default behavior for all popup menus.

This inner class is a JSeparator component customized for use in JPopupMenu components. The addSeparator() method of JPopupMenu returns an instance of this class. This class is a trivial subclass of JSeparator that does nothing except to override the UI delegate class name and ensure that the separator is never vertical.

| JProgressBar | Java 1.2 | |
|
||
| javax.swing | serializable accessible(value) swing component | |
This class implements a progress bar: a component that graphically displays a non-adjustable integer value. It is typically used to display a program's progress on some time consuming task, but can also be used to simulate the display of a graphic equalizer, for example. ProgressMonitor is a useful class that displays a JProgressBar in a dialog box.
Like JScrollBar and JSlider, JProgressBar uses a BoundedRangeModel to maintain its state. The value property is the most important; it specifies the currently displayed value. JProgressBar fires a javax.swing.event.ChangeEvent when its value property changes. value must be between the minimum and maximum values. The orientation property should be one of the HORIZONTAL or VERTICAL constants defined by SwingConstants. Set the borderPainted property to false if you do not want the JProgressBar to display a border around itself.

| JRadioButton | Java 1.2 | |
|
||
| javax.swing | serializable accessible(action,value) swing component | |
This class implements a radio button: a toggle button with default graphics that indicate mutually exclusive behavior. Because JRadioButton supplies its own default and selected icons, you typically do not use the constructors that take Icon arguments. The selection state of a JRadioButton is stored in a JToggleButton.ToggleButtonModel object by default. The initial selection state can be specified in the call to the constructor. The current state can be set with setSelected() and queried with isSelected().
The default graphics of the JRadioButton are designed to indicate to the user that the button represents one of a group of mutually exclusive choices. (The name "radio button" refers to the mechanical station-preset buttons on old-style car radios: only one button could be pressed at a time.) JRadioButton does not implement or enforce mutual exclusion; this is done by adding JRadioButton components to a ButtonGroup object.

| JRadioButtonMenuItem | Java 1.2 | |
|
||
| javax.swing | serializable accessible(action,value) swing component | |
This class implements a radio button that appears within a pulldown or popup menu. Its use is similar to that of JRadioButton. Use isSelected() to query the selection state of the menu item and setSelected() to select or deselect the item. By default, the selection state is stored in a JToggleButton.ToggleButtonModel object. Note that JRadioButtonMenuItem, like JRadioButton, does not implement mutually exclusive selection behavior on its own. Each JRadioButtonMenuItem in a mutually exclusive selection group must be added to a corresponding ButtonGroup object. It is this ButtonGroup that enforces mutual exclusion.

| JRootPane | Java 1.2 | |
|
||
| javax.swing | serializable accessible swing component | |
This component is used internally by all the top-level Swing containers: JWindow, JFrame, JDialog, JApplet, and JInternalFrame. Most applications can simply use these top-level containers; they never need to use JRootPane directly.
JRootPane is a container that manages a fixed hierarchy of children, including a content pane and an optional menubar. You cannot add children directly to a JRootPane; instead, you must add them to the container returned by its getContentPane() method. Each of the top-level Swing containers that uses a JRootPane also provides a getContentPane() method that returns the content pane of its JRootPane. Similarly, to add a menubar to a JRootPane or top-level container that uses JRootPane, you can use the setJMenuBar() method. JRootPane has a custom layout manager that manages its various children. You should not try to set your own layout manager on a JRootPane--instead, set it on the content pane.
The content pane and menubar are not actually direct children of the JRootPane. Instead, they are children of a JLayeredPane that is itself a child of the JRootPane. The JLayeredPane of a JRootPane provides the layering features required for Swing to implement modal dialogs, floating palettes, popup menus, tooltips, and drag-and-drop-style graphical effects. These features are used internally by Swing; only very advanced applications need to use them directly.
In addition to its JLayeredPane, a JRootPane also contains another child, known as the glass pane. This child fills the entire JRootPane and sits on top of the JLayeredPane. The glass pane either must be hidden or must be a transparent component. Otherwise it obscures all other contents of the JRootPane. The glass pane can be used both to intercept mouse events destined for other components within the JRootPane and for the temporary display of graphics on top of the components of a JRootPane. Again, these glass pane features are used internally by Swing, and only advanced applications need to use them directly.

| JScrollBar | Java 1.2 | |
|
||
| javax.swing | serializable accessible(value) swing component | |
This class implements a scrollbar component that can be used to scroll the visible region of some entity, within a maximum and a minimum range. The minimum and maximum properties specify the range within which scrolling takes place. The value property specifies the current value of the scrollbar--the beginning of the visible region. visibleAmount specifies how much of the range is visible at once and also specifies the size of the displayed thumb, or knob, of the scrollbar. The values of these properties are all stored in a BoundedRangeModel object. JScrollBar uses DefaultBoundedRangeModel by default. (The visibleAmount property corresponds to the extent property of BoundedRangeModel.) The orientation property specifies whether the JScrollBar is a horizontal or a vertical scrollbar. Use either the HORIZONTAL or the VERTICAL constant defined by the SwingConstants interface. unitIncrement specifies the amount by which the scrollbar thumb should move when the user clicks on the arrows at either end of the scrollbar. The default is 1. The blockIncrement property specifies the amount that the scrollbar should move when the user scrolls a block at a time (how this is accomplished varies in different look-and-feels).
JScrollBar fires a java.awt.event.AdjustmentEvent when one of the value, minimum, maximum, visibleAmount, or valueIsAdjusting properties changes. Some programs may prefer to instead handle the javax.swing.event.ChangeEvent events generated by the model of the JScrollBar. In either case, if the valueIsAdjusting property of the JScrollBar or its model is true, the change is one in a series of changes. Listeners that prefer not to track these transient changes can ignore events when valueIsAdjusting is true.

| JScrollPane | Java 1.2 | |
|
||
| javax.swing | serializable accessible swing component bean container | |
This class is a container that allows a child component to be scrolled horizontally and vertically. The component to be scrolled is not a direct child of the JScrollPane, so it must not be added directly with the add() method. Instead, it is a child of a JViewport contained within the JScrollPane. You specify the component to be scrolled by passing it to the JScrollPane() constructor or to the setViewportView() method. Any type of component can be used within a JScrollPane, but components that implement the Scrollable interface work best. The horizontalScrollBarPolicy and verticalScrollBarPolicy properties control the policy for displaying scrollbars. The legal values are the various ALWAYS, AS_NEEDED, and NEVER constants defined by the ScrollPaneConstants interface. Another useful property is viewportBorder, which allows you to specify a border to appear around the JViewport that contains the component being scrolled.
In addition to the main scrolled component, JScrollPane supports column header and row header components. The column header appears above the main scrolling component and scrolls horizontally, but not vertically, so that it is always visible at the top of the JScrollPane. Similarly, the row header component scrolls vertically but not horizontally, so it is always visible at the left of the JScrollPane. Specify the row and column header components with setColumnHeaderView() and setRowHeaderView(). The JScrollPane can also display arbitrary components in each of its four corners. Use setCorner() to specify a component for a corner. The ScrollPaneConstants interface defines constants that specify which corner a component should appear in. Note that the space available in the corners of a JScrollPane is determined by the width of the scrollbars and the widths of the column and row headers, if any. The layout management of the scrollable JViewport, the scrollbars, the column and row headers, and the corners is provided by the ScrollPaneLayout class, a specialized java.awt.LayoutManager.
See also the JScrollBar and JViewport components, the ScrollPaneLayout layout manager, and the Scrollable and ScrollPaneConstants interfaces.

This protected inner class is a trivial subclass of JScrollBar that is used for the scrollbars of a JScrollPane. This subclass exists for two simple reasons: to implement the javax.swing.plaf.UIResource interface and to make the scrollbars work with the Scrollable interface.

| javax.swing | serializable accessible swing component | |
This simple component draws a horizontal or vertical line that is as wide or as tall as the component itself. The orientation property is the only property of interest. It should be SwingConstants.HORIZONTAL or SwingConstants.VERTICAL. There are no properties controlling the thickness, color, or other attributes of the JSeparator. Separator objects are commonly used in JPopupMenu and JToolBar components. Note, however, that these components define addSeparator() methods and implement custom subclasses of JSeparator. These custom subclasses have their own UI delegate subclasses, which allows them to provide a visual appearance precisely tailored for menus and toolbars.

| JSlider | Java 1.2 | |
|
||
| javax.swing | serializable accessible(value) swing component | |
This class implements a component that allows the user to drag a knob, or pointer, in order to graphically adjust an integer value. The minimum and maximum properties specify the range of the slider, and the value property specifies the current value. extent specifies the width of the knob and also an adjustment increment. The values of these properties are maintained by a BoundedRangeModel object. By default, JSlider uses a DefaultBoundedRangeModel object. orientation specifies the orientation of the slider; it should be one of the SwingConstants values HORIZONTAL or VERTICAL. If the inverted property is true, the range is inverted to run from right to left or from top to bottom.
A JSlider can display optional tick marks and labels along its length. The paintTicks and paintLabels properties specify whether they should be displayed. majorTickSpacing and minorTickSpacing specify the spacing of long and short tick marks. Note that these spacings are measured in the coordinate space defined by the JSlider minimum and maximum value; they are not pixel spacings. If the snapToTicks property is set true, the user can only adjust the value property to a value at which a tick mark appears. If you set paintLabels and majorTickSpacing, the JSlider automatically displays a numeric label for each major tick mark. You can call createStandardLabels() to force this behavior, even when tick marks are not displayed. You can also specify custom labels by setting the labelTable property to a java.util.Dictionary that maps Integer coordinates to JComponent labels.
A JSlider fires a javax.swing.event.ChangeEvent when one of its value, maximum, minimum, extent, or valueIsAdjusting properties changes. If valueIsAdjusting is true when an event is fired, it means that the event is one of a series of changes. Listeners that do not want to track these rapid-fire transient changes can ignore them.

| JSplitPane | Java 1.2 | |
|
||
| javax.swing | serializable accessible(value) swing component | |
This class is a container that splits itself horizontally or vertically to display two children. The orientation of the pane is specified by the orientation property, which should be set to either the HORIZONTAL_SPLIT or VERTICAL_SPLIT constant. The two children are specified by a pair of properties that depend on the orientation of the JSplitPane. If the orientation is HORIZONTAL_SPLIT, the children are specified with setLeftComponent() and setRightComponent(). For a VERTICAL_SPLITJSplitPane, the children are specified with setTopComponent() and setBottomComponent(). The position of the divider between the two panes of a JSplitPane can be set with setDividerLocation(). The argument can be an integer that specifies a pixel position or a double between 0.0 and 1.0 that specifies a percentage of the size of the JSplitPane.
JSplitPane allows the user to adjust the relative sizes of the two children by dragging the divider that appears between the children. The adjustment is constrained, however, so that a child is never made smaller than its specified minimum size. If the continuousLayout property is set to true, the children are resized continuously while the user drags the divider. If this property is false, however, the child components are not resized until the user finishes the drag. Although the divider location of a JSplitPane can be thought of in terms of the BoundedRangeModel, the JSplitPane implementation does not use a separate model object.

| JTabbedPane | Java 1.2 | |
|
||
| javax.swing | serializable accessible(selection) swing component bean container | |
JTabbedPane is a container that can contain any number of children. It displays one child at a time, but displays a tab for each child. The user can click on these tabs to adjust the currently displayed child. JTabbedPane uses a SingleSelectionModel to keep track of the currently selected and displayed child. By default, the tabs appear at the top of the JTabbedPane. You can override this default, however, with setTabPlacement(). The argument to this method should be one of the TOP, BOTTOM, LEFT, or RIGHT constants defined by the SwingConstants interface.
Although you can add children to a JTabbedPane with the standard add() methods, this does not give you much flexibility in specifying the contents of the tab for that child. Instead, JTabbedPane provides several addTab() methods that allow you to specify the child along with the String, Icon, and tooltip text to use for its tab. A corresponding insertTab() method allows you to specify a child, the contents of its tab, and the position of the tab within the list of tabs. Use setSelectedComponent() or setSelectedIndex() to specify which child is currently displayed. setEnabledAt() allows you to enable or disable a tab, specified by its position within the list of tabs. setDisabledIconAt() allows you to specify an icon to display when a tab is disabled. Various other methods whose names end with "At" allow you to alter properties of individual tabs, specified by position.

| JTable | Java 1.2 | |
|
||
| javax.swing | serializable accessible(selection) swing component | |
JTable is a powerful and complex Swing component for displaying and editing tabular data. JTable relies on the auxiliary classes and interfaces in the javax.swing.table package. Two JTable constructors exist that make it easy to display tabular data that is stored in an Object[][] or in a Vector of rows, where each row is a Vector of cell values. These convenience constructors take an additional array or Vector of objects to be used as column headers for the table. If your data is not already in one of these pure tabular forms, you must provide a javax.swing.table.TableModel object that enables the JTable to find the value for each cell. You typically do this by subclassing javax.swing.table.AbstractTableModel.
When displaying a JTable that contains more than a few rows or columns, it is common to place the JTable within a JScrollPane. JTable components created with the convenience constructors or with a simple default subclass of AbstractTableModel are not editable. However, you can enable editing on a cell-by-cell basis by overriding the isCellEditable() and setValueAt() methods of the AbstractTableModel.
Unlike most Swing components, JTable relies on more than one associated model object. In addition to the TableModel object that contains table data, a JTable also uses a TableColumnModel object to keep track of the columns of the table and their ordering and selection state and a ListSelectionModel used to keep track of selected rows in the table.
The cell values returned by the TableModel are generic objects. By default, JTable knows how to display and edit String, Boolean, and Number values. If you want to display another type of objects, you can create a custom javax.swing.table.TableCellRenderer object and pass it to setDefaultRenderer(). If you want to allow users to edit values of this type, you can create a custom javax.swing.table.TableCellEditor and pass it to setDefaultEditor().

| JTextArea | Java 1.2 | |
|
||
| javax.swing | serializable accessible(text) swing component | |
JTextArea displays multiple lines of plain, unformatted text and allows the user to edit the text. The JTextArea API is designed to be similar to the java.awt.TextArea API.
You can specify the text to be displayed by passing a String to the JTextArea constructor or by using the setText() and getText() methods inherited from the superclass. Specify the number of rows and columns to be displayed by the JTextArea by passing these values to the constructor or by using the setRows() and setColumns() methods. The lineWrap property specifies whether long lines should wrap. The wrapStyleWord property specifies whether lines should wrap at word boundaries or at character boundaries. If you are displaying more than a few lines of text, you probably want to place your JTextArea within a JScrollPane to enable scrolling as needed.
JTextArea is a subclass of javax.swing.text.JTextComponent and inherits many features of that powerful text editor. Many of the most commonly used JTextArea methods are actually inherited from its superclass. They include the getText() and setText() methods already mentioned, as well as setEditable(), getCaretPosition(), and setCaretPosition(). Like its superclass, JTextArea uses a javax.swing.text.Document object as its model. Since a JTextArea displays only plain text, however, you can typically use a simple String object instead.

| JTextField | Java 1.2 | |
|
||
| javax.swing | serializable accessible(text) swing component | |
JTextField allows the user to enter and edit a single line of plain text. JTextField is designed to supersede java.awt.TextField, so it has a similar API. You can set and query the text with the setText() and getText() methods inherited from the superclass. Use setFont() to specify the font in which the text is displayed. Use setColumns() to set the number of characters in the field. Note that the specified number of columns is approximate unless you are using a monospaced font. Note that JTextField inherits a number of useful properties from its superclass. These include enabled, editable, caretPosition, and selectedText.
JTextField fires an ActionEvent to any registered ActionListener objects when the user types Enter. You can specify the action command text sent with the ActionEvent by calling setActionCommand().

| JTextPane | Java 1.2 | |
|
||
| javax.swing | serializable accessible(text) swing component | |
JTextPane is a component for displaying and editing multiline formatted text. When combined with a GUI that allows the user to select fonts, colors, paragraph styles, and so forth, it provides substantial word-processing functionality for any Java application. JTextPane works with documents that implement the javax.swing.text.StyledDocument interface, typically a DefaultStyledDocument. JTextPane also relies on javax.swing.text.StyledEditorKit to provide auxiliary configuration information.
JTextPane does not directly define methods for inserting styled text into the document. You must work directly with the StyledDocument to do that. JTextPane allows the user to edit text but does not provide any means for the user to specify or change the style of that text. Your application must provide additional GUI components (e.g., a menu of available styles or a dialog box for selecting a font) in order to allow the user to select styles.
Call setCharacterAttributes() to specify attributes, such as font size and style, that apply to individual characters. This method either sets the attributes of the currently selected text, or, if there is no selection, specifies attributes to be applied to text inserted in the future. The boolean replace argument indicates whether these attributes should replace the previous attributes or should augment them. setParagraphAttributes() is a similar method, but it sets attributes, such as margins and justification, that apply to entire paragraphs of text.
In addition to displaying formatted text, JTextPane can also display images and arbitrary components. JTextPane provides the insertComponent() and insertIcon() methods to make it easy to insert objects of these types without having to manipulate the StyledDocument object.

| JToggleButton | Java 1.2 | |
|
||
| javax.swing | serializable accessible(action,value) swing component | |
This class implements a toggle button: a button that can be selected or deselected. The user can toggle between the selected and deselected states by clicking the button. Like all Swing buttons, a JToggleButton can display text and an icon. The selection state is typically indicated by the button border and background color. You can also call setIcon() and setSelectedIcon() to specify different icons for the default and selected states. By default, JToggleButton keeps track of its selection state with a JToggleButton.ToggleButtonModel object. JToggleButton is less commonly used than its subclasses JCheckBox and JRadioButton.

| JToolBar | Java 1.2 | |
|
||
| javax.swing | serializable accessible swing component | |
JToolBar is a container that displays a row or column of children, typically JButton children, that represent application tools or actions. JToolBar has two special features that make it useful in applications. First, it has a special add() method that allows you to add an Action object, rather than a Component, to it. When you do this, an appropriate JButton is automatically created. This created button tracks the enabled state of the action, so if the action is disabled, the button becomes disabled as well. The JMenu class has this same ability to accept Action objects as children; the commonly used actions of an application frequently appear in both JMenu and JToolBar components of the application. A JToolBar can contain special separator components that serve to group related tools and separate unrelated tools. You can add a separator to a JToolBar with the special addSeparator() method.
The second special feature of JToolBar is that it is draggable. Unless this feature has been disabled with setFloatable(), a JToolBar displays a special grip that the user can use to drag the toolbar. If the user drags the toolbar out of the window in which it appears, it becomes a floating palette in a window of its own. Additionally, if the JToolBar is positioned against one edge of a container that uses a java.awt.BorderLayout layout manager and if there are no other components positioned against the edges, the user can drag the JToolBar to any other edge of the container. The conventional orientation and position for a JToolBar is a horizontal row of controls positioned just below the menubar at the top of a window. By dragging the JToolBar, however, a user can automatically convert it to a vertical toolbar positioned against the left edge of the window, for example.
JToolBar defines only a few interesting properties. As mentioned earlier, floatable specifies whether the user can drag the JToolBar. orientation specifies whether the JToolBar arranges its children into a horizontal or vertical bar. The value of this property should be one of the SwingConstants constants HORIZONTAL or VERTICAL. The default is HORIZONTAL. Finally, the margin property specifies the amount of space between the border of the toolbar and its children.

| JTree | Java 1.2 | |
|
||
| javax.swing | serializable accessible(selection) swing component | |
JTree is a powerful Swing component for displaying hierarchical, tree-structured data in outline form. The user can expand and collapse the outline to show or hide the children of any node in the tree. The user can also select and optionally edit the values displayed in the tree.
JTree relies on the classes and interfaces in the javax.swing.tree package. Most importantly, it uses a TreeModel object to encapsulate the tree data it displays. If your data already has a hierarchical structure, you should implement a TreeModel class to serve as an intermediary between your data structures and the JTree component. If your data is not implicitly hierarchical, you can arrange it into a hierarchy by implementing the TreeNode or MutableTreeNode interface or by encapsulating your objects within DefaultMutableTreeNode objects that implement these interfaces for you. Once you have done this, you can rely on the default JTree model, DefaultTreeModel.
JTree also defines constructors that accept tree data in the form of an Object[], a Vector, or a Hashtable. If your data is relatively simple and you can express it in one of these forms, it is easy to use one of these constructors to display your data. If you specify a vector or object array, the elements of the vector or array become the nodes of the tree. If any of those elements are a vector, array, or hashtable, the contents of that element become the children of that node. If you specify a Hashtable, the keys of the hashtable become the nodes of the tree and the values of the hashtable become the children of those nodes. This is particularly useful, of course, if the hashtable values are arrays or vectors.
By default, tree nodes are not editable. You can change this, however, with the setEditable() method. The selection state and selection mode of a JTree is maintained by a javax.swing.tree.TreeSelectionModel object. By default, JTree uses a DefaultTreeSelectionModel object. You can set your own object with setSelectionModel(). Use the setSelectionMode() method of the TreeSelectionModel to specify the type of selection that is supported by the JTree. To disable selection in a JTree altogether, pass null to setSelectionModel().
JTree defines a number of methods for setting and querying the current selection state of the tree. It also defines methods for collapsing and expanding nodes and for querying nodes to determine whether they are expanded. These methods use two different techniques for referring to a particular node in the tree. One technique is to specify the integer row number at which the item appears. While this is a convenient way to refer to an item that the user has selected, for example, it does not map naturally to an item in the TreeModel. The other way to refer to an item in a JTree is with a javax.swing.tree.TreePath object. A TreePath is essentially an array of objects that contains the node itself and all of its ancestors up to the root of the tree. The first element in the array is the root, and the last element is the tree node that is being referred to. The methods getPathForRow() and getRowForPath() allow you to convert from one node representation to another. Related methods convert between X, Y coordinates (such as the coordinates contained in a MouseEvent) and the nearest TreePath or tree row.
JTree displays its nodes using a javax.swing.tree.TreeCellRenderer object. By default, it uses DefaultTreeCellRenderer, which displays any object in the tree in text form by calling its toString() method. If you want to display custom objects in a tree, you can implement your own TreeCellRenderer and pass an instance to setCellRenderer(). JTree does not allow its nodes to be edited by default, but when editing is enabled, it is done with a TreeCellEditor object. The DefaultTreeCellEditor allows editing of String and Boolean nodes. You can implement your own TreeCellEditor if you want to allow the user to edit other node types.
JTree defines quite a few methods for querying and setting the state of the tree. The purpose of most of these methods is fairly obvious. One thing to note is that different methods use the word "visible" to mean different things. The methods isVisible() and makeVisible() use "visible" to refer to a node that is displayed under an expanded parent. Under this definition, a node may be visible even if it is currently scrolled off the screen. All other methods, such as scrollPathToVisible(), use "visible" to mean that a node is actually on the screen and currently visible to the user.
JTree implements the Scrollable interface, and, unless you are displaying a very small, fixed-size tree, you should almost always place a JTree within a JScrollPane container. If you are using JTree to view a large amount of data, if all the nodes are of the same type, and if the TreeModel has an efficient implementation, you may get better performance by passing true to setLargeModel().

| JWindow | Java 1.2 | |
|
||
| javax.swing | serializable accessible swing component bean container | |
This class is the Swing analog of the java.awt.Window class. It is a basic heavyweight top-level window with no titlebar or other frame decorations. Most applications use JFrame and JDialog in preference to JWindow. Like JFrame and JDialog, JWindow is a RootPaneContainer, which means that it has an automatically created JRootPane as its single child. You are not allowed to add children or set a layout manager on the JWindow itself. Instead, you must use the container returned by the getContentPane().

| KeyStroke | Java 1.2 | |
|
||
| javax.swing | serializable | |
This class represents a single keystroke, specified either as a character or, more flexibly, as a keycode plus a set of keyboard modifiers. KeyStroke objects are immutable, and the KeyStroke class maintains a cache of the objects. There is no public KeyStroke constructor. Instead, call one of the static getKeyStroke() methods to obtain a reference to a KeyStroke object that represents the desired keystroke. Note that some versions of getKeyStroke() take a boolean argument that specifies whether the KeyStroke represents a key release event instead of a key press event. The keyCode argument to getKeyStroke() should be one of the VK_ virtual key constants defined by java.awt.event.KeyEvent. The modifiers argument should be a bitmask composed of the ALT_MASK, CTRL_MASK, META_MASK, and SHIFT_MASK constants defined by java.awt.Event.
See also the registerKeyboardAction() method of JComponent, the setAccelerator() method of JMenuItem, and javax.awt.swing.text.Keymap.

| ListCellRenderer | Java 1.2 | |
|
||
| javax.swing | ||
This interface defines the method that must be implemented by any object that wants to be able to render items in a JList component. Most applications can rely on the default behavior of JList (to use a DefaultListCellRenderer) and never need to implement or use this interface. getListCellRendererComponent() is passed information about the list item that is to be rendered; it should return a lightweight java.awt.Component capable of rendering the list item. The JList object first positions this component at the desired location by calling its setBounds() method and then asks the component to draw itself by calling paint(). Note, however, that the component is never actually added to the component hierarchy.

| ListModel | Java 1.2 | |
|
||
| javax.swing | model | |
This interface defines the methods that must be implemented by any object that wants to maintain a list of values for display in a JList or similar component. A ListModel must be able to return the size of the list, return any numbered element of the list, and fire a ListDataEvent event to any registered ListDataListener objects whenever the contents of the list changes. ListModel implementations that represent immutable lists can provide dummy no-op implementations of the event registration methods. Most applications do not need to implement this interface; they can work with JList directly or use the DefaultListModel class.

| LookAndFeel | Java 1.2 | |
|
||
| javax.swing | ||
This abstract class defines the methods that a pluggable look-and-feel must implement. It also defines some useful static convenience methods. Application programmers should never have to use or subclass this class. If you are implementing a look-and-feel, you have to subclass this class and define the abstract methods, of course. You probably also want to override the default no-op initialize() and getDefaults() methods. Finally, you have to provide implementations of all the abstract classes in javax.swing.plaf.

||
| javax.swing | ||
This interface defines methods that all menu components must implement. The methods allow menu navigation and event handling to be performed in a standard way. Application programmers should never have to implement this interface or use the methods it defines, unless they want to place components other than JMenuItem and its subclasses into menus. See also MenuSelectionManager.

|
||
| javax.swing | ||
This class defines methods that manipulate hierarchies of menus. Application programmers do not need to use this class. There is only one instance of MenuSelectionManager, returned by the static defaultManager() method. Menu items rely on MenuSelectionManager for implementations of MenuElement methods, and MenuSelectionManager relies on the methods of the MenuElement interface to allow it to traverse menu hierarchies.

| OverlayLayout | Java 1.2 | |
|
||
| javax.swing | serializable layout manager | |
This layout manager arranges the children of the container it manages so that the alignment points (specified with the setAlignmentX() and setAlignmentY() methods of JComponent) are on top of each other. This usually means that the children overlap. AbstractButton relies on this layout manager, but applications rarely use it.

Hierarchy: Object-->OverlayLayout(java.awt.LayoutManager2(java.awt.LayoutManager),Serializable)
| ProgressMonitor | Java 1.2 | |
|
||
| javax.swing | ||
This class implements a progress monitor. After creating a ProgressMonitor, a program periodically calls setProgress() to indicate its progress toward the completion of a task. Unless progress is quite rapid, the ProgressMonitor displays a dialog box that uses a JProgressBar to display progress to the user. Call setNote() to set the text to display in the dialog box. You can also specify a permanent title or heading for the dialog box with the second argument to the constructor. The ProgressMonitor dialog box automatically closes when the progress property reaches the value of the maximum property. If you want to close it before the task completes, call close().
ProgressMonitor suffers from an important flaw: if the user clicks the Cancel buttons in the dialog box, the dialog is dismissed. Unfortunately, the dialog does not fire any event to indicate that this has happened, so your program must call isCancelled() each time it calls setProgress(), to determine whether the user has requested that the operation be cancelled. A related flaw is that the dialog box contains an extraneous Okay button that behaves just like the Cancel button.

| ProgressMonitorInputStream | Java 1.2 | |
|
||
| javax.swing | ||
This class combines a java.io.InputStream with a ProgressMonitor to display a program's progress in reading a stream. It is useful when reading a long file or when doing time-consuming processing on data from a shorter file. If the user clicks the Cancel button in the dialog, the next call to read data from the stream results in an InterruptedIOException. A ProgressMonitorInputStream can only be wrapped around a stream whose available() method returns the total remaining number of bytes in the stream, such as a java.io.FileInputStream. It does not work with java.io.PipedInputStream, for example.

| Renderer | Java 1.2 | |
|
||
| javax.swing | ||
This interface defines the basic methods that must be implemented by any class that wants to render a value of some specified type on behalf of a general-purpose component, such as a JList. In practice, the setValue() method defined by this interface is under-constrained, and this interface is unused in the Swing API. Three interfaces, with more specialized methods, are used in its place: ListCellRenderer, javax.swing.table.TableCellRenderer and javax.swing.tree.TreeCellRenderer.

| RepaintManager | Java 1.2 | |
|
||
| javax.swing | ||
This class manages the repaint and relayout process for all Swing components in an application. It also provides a shared off-screen image for Swing components that perform double-buffering. RepaintManager is an integral part of the Swing GUI framework and is used extensively by JComponent internals. Applications rarely need to use it directly. If yours does, you can obtain the current RepaintManager with the static currentManager() method.

| RootPaneContainer | Java 1.2 | |
|
||
| javax.swing | ||
This interface is implemented by all Swing window and applet classes that have a JRootPane as their single child. It defines getRootPane() to return that JRootPane. It also defines other methods to return the various children of the JRootPane. getContentPane() is the most frequently used method of this interface: it returns the container to which children are added.

|
||
| javax.swing | ||
This class defines a variety of static methods that are useful in Swing applications. Highlights include:
Place the specified Runnable object on the event queue, so that its run() method is invoked (later) from the event dispatch thread. invokeLater() returns immediately; invokeAndWait() blocks until the run() method has run. Since Swing is not generally thread safe, these methods are useful when you need to update the GUI from a thread that is not the event dispatch thread.
Determines whether the current thread is the event dispatch thread.
Traverses the entire component tree rooted at the specified component and asks each component to update its UI delegate. This method is useful after you have changed the pluggable look-and-feel of a running application.
Determine whether a specified MouseEvent involves the left, middle, or right mouse button. For portability reasons, this information is encoded in the modifiers property that the MouseEvent inherits. These methods simplify access to it.
Given a component and a component class, this method searches the ancestors of the component until it finds one of the specified class. getRoot(), getRootPane(), windowForComponent(), and getAncestorNamed() are related methods.

Optionally, it may continue to fire action events at specified time intervals. This class is useful for triggering delayed or repeated actions, such as animations. After creating a Timer object, adding one or more ActionListener objects, and setting any necessary properties, call start() to make the Timer object start timing and firing events. If you have configured the Timer to fire events repeatedly, use the stop() method when you want the events to stop.
The initialDelay property specifies the time in milliseconds between the invocation of the start() method and the firing of the first ActionEvent. The repeats property specifies whether the Timer fires events repeatedly. If repeats is true, the delay property specifies the interval (in milliseconds) between repeated events. If the delay property is set to a short interval or if the ActionEvent triggers a complex action, the Timer may sometimes get behind and develop a backlog of events. Set the coalesce property to true if the Timer is allowed to coalesce multiple pending events into a single ActionEvent in this situation. The Timer constructor sets the repeats and coalesce properties to true, so be sure to change these properties if you don't want that behavior. The constructor also sets both the delay and initialDelay properties to the specified interval. The static setLogTimers() method is useful when debugging code that uses the Timer class. Passing true to this method causes Timer to print a debugging message to standard output each time it fires an event.

| ToolTipManager | Java 1.2 | |
|
||
| javax.swing | ||
This class manages tooltips for a Swing application. There is only one ToolTipManager per application; you can obtain a reference to it with the static sharedInstance() method. Any Swing component that has a tooltip set on it (with setToolTipText()) is automatically registered with the ToolTipManager, so applications do not usually have to work with this class explicitly. If you want to explicitly register or unregister a component without setting its tooltip text, you can do so with registerComponent() and unregisterComponent(), respectively.
To disable all tooltips in an application (at the request of an advanced user, for example), set the enabled property to false. The other ToolTipManager properties are various delays that affect the behavior of tooltips. These values are user preferences, and an application should not modify them except in response to an explicit user request made through some kind of preferences dialog or control panel.

| UIDefaults | Java 1.2 | |
|
||
| javax.swing | cloneable serializable collection | |
UIDefaults is a Hashtable subclass used to maintain a table of named resources for use by a look-and-feel implementation. Like any hashtable, UIDefaults defines a get() and a put() method. In addition, it defines numerous more specific getXXX() methods that are used to look up resources of specific types. Unless you are defining a custom look-and-feel, you probably do not have to use this class explicitly.
The generic get() method and all the more specific methods that use it have a special behavior if the returned resource value implements either of the inner interfaces defined by UIDefaults. If the returned object is a UIDefaults.ActiveValue, the value returned by the get() method is computed by calling the createValue() method of the ActiveValue object. Similarly, if the returned value is a LazyValue, the final return value of the get() method is computed by calling the createValue() method of the LazyValue object. Once this computation is done the first time, however, the LazyValue is replaced in the UIDefaults table with the computed value it yielded. This is a useful technique for resources such as icons that have to be read in from external files. It prevents them from being created unless they are actually needed.

| javax.swing | ||
This interface defines a special kind of resource that can be stored in a UIDefaults hashtable. When the get() method of UIDefaults finds a ActiveValue in the table, it does not return the ActiveValue object. Instead, it invokes its createValue() method and returns the object returned by that method.

This interface defines a special kind of resource that can be stored in a UIDefaults hashtable. When the get() method of UIDefaults finds an LazyValue in the table, it does not return the LazyValue object. Instead, it invokes its createValue() method.

| UIManager | Java 1.2 | |
|
||
| javax.swing | serializable | |
The static methods of this class perform a number of look-and-feel related functions. setLookAndFeel() is the most important. It takes a LookAndFeel object or the class name of the desired look-and-feel and makes it the current look-and-feel. getLookAndFeel() returns the LookAndFeel object that represents the current look-and-feel. getCrossPlatformLookAndFeelClassName() and getSystemLookAndFeelClassName() return class names for the default Java look-and-feel and for the look-and-feel that mimics the native platform look-and-feel, if one exists. getInstalledLookAndFeels() returns information about all look-and-feels that are installed on the system.
The UIManager also manages user interface defaults specified both by the current look-and-feel and by the application. The get() method looks up a value for the named key, checking the table of application defaults first and then checking the defaults specified by the look-and-feel. The put() method inserts a new key/value binding into the application defaults table; it does not modify the look-and-feel defaults. UIManager defines various other type-specific getXXX() methods that can be used to look up default UI resources of various types.
Although all the methods of UIManager are static, they are implemented in such a way that each separate application context can independently set its own look-and-feel defaults. This means, for example, that multiple applets running in the same Java VM can install and use different look-and-feel implementations.

| WindowConstants | Java 1.2 | |
|
||
| javax.swing | ||
This interface defines three constants that describe possible actions that can be taken when the user requests that a window be closed. These three constants are the legal arguments to the setDefaultCloseOperation() methods of JFrame, JInternalFrame, and JDialog. Note that setDefaultCloseOperation() specifies only the default action when the user tries to close the window. An application that registers a WindowListener object can augment this default operation with one of its own.
