All Implemented Interfaces:

javax.accessibility.Accessible, java.util.EventListener, java.awt.event.FocusListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.lang.Runnable, java.io.Serializable

public class VirtualWindowUI

extends java.awt.Window

implements java.lang.Runnable, java.awt.event.FocusListener

This UI part of the VirtualWindow framework is in charge of intercepting all Window events related to drawing, in order to keep the invisible facade.

There is a problem with the transparency right now. I'm investigating a solution. The final (and unwanted) solution is to capture the background behind the Window, and display that on paint( Graphics ) calls.

WARNING: if the screen size is to resize, then this will not work correctly.

Constructor Detail

VirtualWindowUI

public VirtualWindowUI(java.awt.Window owner)

Creates a disabled window with no parent.

Method Detail

setGlassEnabled

public void setGlassEnabled(boolean on)

Sets the inner state for displaying the glass pane. If the pane is enabled, then the glass pane will attempt to maximize itself and keep itself on the foreground at all costs.

This should be the only method where the inner enableGlass field is manipulated. Any inner testing against this variable needs to be synchronized.

Parameters:

on - true if the glass pane is enabled (active and intercepting events), or false if is disabled.

isGlassEnabled

public boolean isGlassEnabled()

Retrieves the current glass enabled state.

Returns:

true if the glass pane is enabled (active and intercepting events), or false if is disabled.

maximize

public void maximize()

Enlarge the window to the size of the screen.

getCoveredScreen

public java.awt.Rectangle getCoveredScreen()

Retrieve the size of the covered window.

setBackground

public void setBackground(java.awt.Image img)

Update the background image. This may set the background to null.

show

public void show()

hide

public void hide()

dispose

public void dispose()

update

public void update(java.awt.Graphics g)

paint

public void paint(java.awt.Graphics g)

run

public void run()

Thread runner to keep the window in the front.

Specified by:

run in interface java.lang.Runnable

focusGained

public void focusGained(java.awt.event.FocusEvent fe)

Specified by:

focusGained in interface java.awt.event.FocusListener

focusLost

public void focusLost(java.awt.event.FocusEvent fe)

Specified by:

focusLost in interface java.awt.event.FocusListener

finalize

protected void finalize()
                 throws java.lang.Throwable

Throws:

java.lang.Throwable - thrown if the super throws anything.
