Hello

I have a problem.
I have a program that it makes a transparent windows (whit java) I can execute whit eclipse, good.

I have a plug-in too, and I want to join both.
In my plug in I added a buton in the toolbar.
The butons's handler is a class that it's makes a transparent windows, but this isn't transparent, before this windows (YES) was trasnparent (when i execute her).

If before ths windos was transparent, why isn't it when i add it at plugin??

is This for SWT???????

Help me PLEASE.
Thanks a lot



I edit:

Yes i can do it.

Hi,

Your snippet does not contain any swt. Am I missing something? Are you
saying that you have an AWT/Swing window that is transparent when shown from
a stand-alone application but is not transparent when shown from an eclipse
plug-in?
