Transparent window

[Carlos Eduardo Medaglia Dyonisio <carlos dyonisio digitro com br>]

Hi all!

I'm needing to have a transparent window, like gkrellm and mplayer, but
I'm not having success. I've found a few messages in this list about
it, but I didn't find any good answer.

What I need is a window with no borders and with rounded corners. I've
noticied that gkrellm does it, and I've looked its code, but I can't
understand how gkrellm does this.

Any help would be greatly appreciated!

Best regards,
Carlos Eduardo
