JWindow (Java 2 Platform SE 5.0) (original) (raw)

javax.swing

Class JWindow

java.lang.Object extended by java.awt.Component java.awt.Container java.awt.Window javax.swing.JWindow

All Implemented Interfaces:

ImageObserver, MenuContainer, Serializable, Accessible, RootPaneContainer

public class JWindow

implements Accessible, RootPaneContainer

A JWindow is a container that can be displayed anywhere on the user's desktop. It does not have the title bar, window-management buttons, or other trimmings associated with a JFrame, but it is still a "first-class citizen" of the user's desktop, and can exist anywhere on it.

The JWindow component contains a JRootPane as its only child. The contentPane should be the parent of any children of the JWindow. As a conveniance add and its variants, remove andsetLayout have been overridden to forward to thecontentPane as necessary. This means you can write:

   window.add(child);

And the child will be added to the contentPane. The contentPane will always be non-null. Attempting to set it to null will cause the JWindow to throw an exception. The default contentPane will have aBorderLayout manager set on it. Refer to RootPaneContainer for details on adding, removing and setting the LayoutManager of a JWindow.

Please see the JRootPane documentation for a complete description of the contentPane, glassPane, andlayeredPane components.

In a multi-screen environment, you can create a JWindow on a different screen device. See Window for more information.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeansTM has been added to the java.beans package. Please see XMLEncoder.

Field Detail

rootPane

protected JRootPane rootPane

The JRootPane instance that manages thecontentPane and optional menuBar for this frame, as well as the glassPane.

rootPaneCheckingEnabled

protected boolean rootPaneCheckingEnabled

If true then calls to add and setLayout will be forwarded to the contentPane. This is initially false, but is set to true when the JWindow is constructed.

accessibleContext

protected AccessibleContext accessibleContext

The accessible context property.

Constructor Detail

JWindow

public JWindow()

Creates a window with no specified owner. This window will not be focusable.

This constructor sets the component's locale property to the value returned by JComponent.getDefaultLocale.

Throws:

[HeadlessException](../../java/awt/HeadlessException.html "class in java.awt") - ifGraphicsEnvironment.isHeadless() returns true.

JWindow

public JWindow(GraphicsConfiguration gc)

Creates a window with the specified GraphicsConfiguration of a screen device. This window will not be focusable.

This constructor sets the component's locale property to the value returned by JComponent.getDefaultLocale.

Parameters:

gc - the GraphicsConfiguration that is used to construct the new window with; if gc is null, the system default GraphicsConfiguration is assumed

Throws:

[HeadlessException](../../java/awt/HeadlessException.html "class in java.awt") - IfGraphicsEnvironment.isHeadless() returns true.

[IllegalArgumentException](../../java/lang/IllegalArgumentException.html "class in java.lang") - if gc is not from a screen device.

Since:

1.3

JWindow

public JWindow(Frame owner)

Creates a window with the specified owner frame. If owner is null, the shared owner will be used and this window will not be focusable. Also, this window will not be focusable unless its owner is showing on the screen.

This constructor sets the component's locale property to the value returned by JComponent.getDefaultLocale.

Parameters:

owner - the frame from which the window is displayed

Throws:

[HeadlessException](../../java/awt/HeadlessException.html "class in java.awt") - if GraphicsEnvironment.isHeadless() returns true.

JWindow

public JWindow(Window owner)

Creates a window with the specified owner window. This window will not be focusable unless its owner is showing on the screen. If owner is null, the shared owner will be used and this window will not be focusable.

This constructor sets the component's locale property to the value returned by JComponent.getDefaultLocale.

Parameters:

owner - the window from which the window is displayed

Throws:

[HeadlessException](../../java/awt/HeadlessException.html "class in java.awt") - ifGraphicsEnvironment.isHeadless() returns true.

JWindow

public JWindow(Window owner, GraphicsConfiguration gc)

Creates a window with the specified owner window andGraphicsConfiguration of a screen device. Ifowner is null, the shared owner will be used and this window will not be focusable.

This constructor sets the component's locale property to the value returned by JComponent.getDefaultLocale.

Parameters:

owner - the window from which the window is displayed

gc - the GraphicsConfiguration that is used to construct the new window with; if gc is null, the system default GraphicsConfiguration is assumed, unless owner is also null, in which case the GraphicsConfiguration from the shared owner frame will be used.

Throws:

[HeadlessException](../../java/awt/HeadlessException.html "class in java.awt") - ifGraphicsEnvironment.isHeadless() returns true.

[IllegalArgumentException](../../java/lang/IllegalArgumentException.html "class in java.lang") - if gc is not from a screen device.

Since:

1.3

Method Detail

windowInit

protected void windowInit()

Called by the constructors to init the JWindow properly.

createRootPane

protected JRootPane createRootPane()

Called by the constructor methods to create the defaultrootPane.

isRootPaneCheckingEnabled

protected boolean isRootPaneCheckingEnabled()

Returns whether calls to add and setLayout are forwarded to the contentPane.

Returns:

true if add and setLayout are fowarded; false otherwise

update

public void update(Graphics g)

Calls paint(g). This method was overridden to prevent an unnecessary call to clear the background.

Parameters:

g - the Graphics context in which to paint

Parameters:

enabled - true if add and setLayout are forwarded, false if they should operate directly on theJWindow.

See Also:

addImpl

protected void addImpl(Component comp, Object constraints, int index)

Adds the specified child Component. This method is overridden to conditionally forwad calls to thecontentPane. By default, children are added to the contentPane instead of the frame, refer to RootPaneContainer for details.

Overrides:

[addImpl](../../java/awt/Container.html#addImpl%28java.awt.Component, java.lang.Object, int%29) in class [Container](../../java/awt/Container.html "class in java.awt")
