Class JWindow

java.lang.Object

java.awt.Component

java.awt.Container

java.awt.Window

javax.swing.JWindow

All Implemented Interfaces:

ImageObserver, MenuContainer, Serializable, Accessible, RootPaneContainer

public class JWindow
extends Window
implements Accessible, RootPaneContainer

Unlike JComponent derivatives, JWindow inherits from java.awt.Window. But also lets a look-and-feel component to its work.

Constructor Detail

JWindow

public JWindow()

Creates a new JWindow that has a shared invisible owner frame as its parent.

JWindow

public JWindow(GraphicsConfiguration gc)

Creates a new JWindow that uses the specified graphics environment. This can be used to open a window on a different screen for example.

Parameters:

gc - the graphics environment to use

JWindow

public JWindow(Frame owner)

Creates a new JWindow that has the specified owner frame. If owner is null, then an invisible shared owner frame is installed as owner frame.

Parameters:

owner - the owner frame of this window; if null a shared invisible owner frame is used

JWindow

public JWindow(Window owner)

Creates a new JWindow that has the specified owner window. If owner is null, then an invisible shared owner frame is installed as owner frame.

Parameters:

owner - the owner window of this window; if null a shared invisible owner frame is used

JWindow

public JWindow(Window owner,
       GraphicsConfiguration gc)

Creates a new JWindow for the given graphics configuration and that has the specified owner window. If owner is null, then an invisible shared owner frame is installed as owner frame. The gc parameter can be used to open the window on a different screen for example.

Parameters:

owner - the owner window of this window; if null a shared invisible owner frame is used

gc - the graphics configuration to use

Method Detail

windowInit

protected void windowInit()

getPreferredSize

public Dimension getPreferredSize()

Description copied from class: Container

Returns the preferred size of this container.

Overrides:

getPreferredSize in class Container

Returns:

The preferred size of this container.

setLayout

public void setLayout(LayoutManager manager)

Description copied from class: Container

Sets the layout manager for this container to the specified layout manager.

Overrides:

setLayout in class Container

Parameters:

manager - The new layout manager for this container.

addImpl

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

Description copied from class: Container

This method is called by all the add() methods to perform the actual adding of the component. Subclasses who wish to perform their own processing when a component is added should override this method. Any subclass doing this must call the superclass version of this method in order to ensure proper functioning of the container.

Overrides:

addImpl in class Container

Parameters:

comp - The component to be added.

constraints - The layout constraints for this component, or null if there are no constraints.

index - The index in the component list to insert this child at, or -1 to add at the end of the list.

remove

public void remove(Component comp)

Description copied from class: Container

Removes the specified component from this container.

Overrides:

remove in class Container

Parameters:

comp - The component to remove from this container.

isRootPaneCheckingEnabled

protected boolean isRootPaneCheckingEnabled()

setRootPaneCheckingEnabled

protected void setRootPaneCheckingEnabled(boolean enabled)

update

public void update(Graphics g)

Description copied from class: Container

Updates this container. The implementation of this method in this class forwards to any lightweight components in this container. If this method is subclassed, this method should still be invoked as a superclass method so that lightweight components are properly drawn.

Overrides:

update in class Container

Parameters:

g - The graphics context for this update.

See Also:

Component.paint(Graphics), Component.repaint()

processKeyEvent

protected void processKeyEvent(KeyEvent e)

Description copied from class: Component

Called when a key event is dispatched and component events are enabled. This method passes the event along to any listeners that are attached.

Overrides:

processKeyEvent in class Component

Parameters:

e - the KeyEvent to process

See Also:

KeyListener, Component.addKeyListener(KeyListener), Component.enableEvents(long)

getAccessibleContext

public AccessibleContext getAccessibleContext()

Description copied from class: Window

Gets the AccessibleContext associated with this Window. The context is created, if necessary.

Specified by:

getAccessibleContext in interface Accessible

Overrides:

getAccessibleContext in class Window

Returns:

the associated context

paramString

protected String paramString()

Description copied from class: Container

Returns a string representing the state of this container for debugging purposes.

Overrides:

paramString in class Container

Returns:

A string representing the state of this container.
