JDesktopIcon problems

[Ike]

I have a class which extend JInternalFrame. Whenever this class is invoked,
it always spits out the following exception, listed below. For the life of
me, I cannot track this down.

Is anyone aware of what I may be missing here to cause this? Thanks, Ike

UIDefaults.getUI() failed: no ComponentUI class for:
javax.swing.JInternalFrame$JDesktopIcon[,0,0,0x0,invalid,hidden,alignmentX=0
..0,alignmentY=0.0,border=,flags=0,maximumSize=,minimumSize=,preferredSize=]

Hi,

Are you setting the "look and feel " yourself in your app ?

Arnaud

Yes, exactly.

So just a guess,

Maybe the L&F you're using does not provide any valid UI for
JInternalFrame$JDesktopIcon

Try to launch your app with the default L&F to check this.

Is there a workaround I could to -- override a method perhaps, with a
try-catch such that the exception would not appear? Thanks, Ike

I'm afraid that try-catching this Exception won't be enough.

You may have to do some things like :

UIManager.put(XXX, YYY);

Where XXX is the String used to identify the JInternalFrame$JDesktopIcon's
UI
and YYY the ui class for it.

e.g :

UIManager.put("DesktopIconUI", "javax.swing.plaf.basic.
BasicDesktopIconUI");


I'm no L&F expert though, so you may want to repost this problem to
comp.lang.java.gui .

Arnaud
