I see that in some cases the window gets hidden/shown when changing
L&Fs (like when switching from Windows to Metal), and in some
it doesn't (Windows <-> Nimbus). The exception is only thrown
in the first case.
This is because the demo disposes and re-creates the frame when
switching to a L&F which can/can't render its decorations (see
test/ribbon/BasicCheckRibbon.java):
if (canBeDecoratedByLAF == wasDecoratedByOS) {
boolean wasVisible = frame.isVisible();
frame.setVisible(false);
frame.dispose();
if (!canBeDecoratedByLAF) {
// see the java docs under the method
// JFrame.setDefaultLookAndFeelDecorated(boolean
// value) for description of these 2 lines:
frame.setUndecorated(false);
frame.getRootPane().setWindowDecorationStyle(
JRootPane.NONE);
} else {
frame.setUndecorated(true);
frame.getRootPane().setWindowDecorationStyle(
JRootPane.FRAME);
}
frame.setVisible(wasVisible);
wasDecoratedByOS = !frame.isUndecorated();
}
Nothing illegal here, so the exception is a bug, please file it.
Thanks,
Dmitri

It seems that there is a problem with d3d pipeline, because there is no such exception
when running with "-Dsun.java2d.d3d=false".
I am running on the system:
[code]
java -version
java version "1.6.0_11"
Java(TM) SE Runtime Environment (build 1.6.0_11-b03)
Java HotSpot(TM) Client VM (build 11.0-b16, mixed mode, sharing)

[/code]
And it is reproduced on my home computer with NVIDIA 7600GS also.
Is this a bug in d3d pipeline? Or there is something wrong with the flamingo
ribbon demo?
