Transparent JDesktopPane

Show all headers | View raw

  To: comp.lang.java.gui
Hello,

I was wondering: If a JDekstopPane is made transparent
eg:
JFrame jf = new JFrame("Frame");
jf.getContentPane().add(new JDesktopPane());
AWTUtilities.setWindowOpacity(jf, 0.75f);

Is it possible to have intranparent (or less transparent) 
JInternalFrames? AWTUtilities.setWindowOpacity only applies to Windows...

Imho this could be difficult, 'cause SwingCompnents are 
lightweight-Components and a DesktopPane / InternalFrame does not have a 
corresponding awt class)

Is there a way to not draw the JDesktopPane's backround (via some paint 
(Graphics g) magic - for instance) and use an underlaying JWindow for 
the opacity-effect? Furthermore, how can I prevent painting the Pane's 
background?

Thanks in advance,
Keep smiling
yanosz
