Class JWindow

Implemented Interfaces:
Accessible, ImageObserver, MenuContainer, RootPaneContainer, Serializable

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.

Since:
1.2

rootPane

protected JRootPane rootPane

rootPaneCheckingEnabled

protected boolean rootPaneCheckingEnabled

Constructor Details

JWindow

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

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(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(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 Details

addImpl

protected void addImpl(Component comp,
                       Object constraints,
                       int index)
Overrides:
addImpl in interface Container

createRootPane

protected JRootPane createRootPane()

getAccessibleContext

public AccessibleContext getAccessibleContext()
If a component supports the Accessibility API then this method should not return null. Only classes which must extend an accessible class, but must not itself be accessible, may return null.
Specified by:
getAccessibleContext in interface Accessible
Overrides:
getAccessibleContext in interface Window
Returns:
the context associated with this accessible object

getContentPane

public Container getContentPane()
getContentPane
Specified by:
getContentPane in interface RootPaneContainer

getGlassPane

public Component getGlassPane()
getGlassPane
Specified by:
getGlassPane in interface RootPaneContainer

getLayeredPane

public JLayeredPane getLayeredPane()
getLayeredPane
Specified by:
getLayeredPane in interface RootPaneContainer

getPreferredSize

public Dimension getPreferredSize()
Returns the component's preferred size.
Overrides:
getPreferredSize in interface Container
Returns:
the component's preferred size

getRootPane

public JRootPane getRootPane()
getRootPane
Specified by:
getRootPane in interface RootPaneContainer

isRootPaneCheckingEnabled

protected boolean isRootPaneCheckingEnabled()

paramString

protected String paramString()
Returns a debugging string representing this component. The string may be empty but not null.
Overrides:
paramString in interface Container
Returns:
a string representing this component

processKeyEvent

protected void processKeyEvent(KeyEvent e)
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 interface Component
Parameters:
e - the KeyEvent to process
Throws:
NullPointerException - if e is null
Since:
1.1

remove

public void remove(Component comp)
Overrides:
remove in interface Container

setContentPane

public void setContentPane(Container contentPane)
setContentPane
Specified by:
setContentPane in interface RootPaneContainer
Parameters:
contentPane - TODO

setGlassPane

public void setGlassPane(Component glassPane)
setGlassPane
Specified by:
setGlassPane in interface RootPaneContainer
Parameters:
glassPane - TODO

setLayeredPane

public void setLayeredPane(JLayeredPane layeredPane)
setLayeredPane
Specified by:
setLayeredPane in interface RootPaneContainer
Parameters:
layeredPane - TODO

setLayout

public void setLayout(LayoutManager manager)
Overrides:
setLayout in interface Container

setRootPane

protected void setRootPane(JRootPane root)

setRootPaneCheckingEnabled

protected void setRootPaneCheckingEnabled(boolean enabled)

update

public void update(Graphics g)
Updates this component. This is called for heavyweight components in response to Component.repaint(). The default implementation simply forwards to Component.paint(Graphics). The coordinates of the graphics are relative to this component. Subclasses should call either super.update(g) or paint(g).
Overrides:
update in interface Container
Parameters:
g - the graphics context for this update

windowInit

protected void windowInit()
