Hi,

I created a cross-platform GUI toolkit called fpGUI. It talks directly
to XLib and tries to have as little as possible dependencies as
possible. The toolkit is a "windowed" toolkit - every widget is a window.

For example: If I have one Form (window) with a Button and TextLabel
component, that totals three windows. One top-level window and two
embedded windows.

I would like the TextLabel or Button widgets to have transparent
backgrounds. My goal is to tile a bitmap on the Form canvas and have the
TextLabel overlay on top of that.

Is it possible to create widgets with transparent background? If so,
has anybody got some sample code (or know of another toolkit I can look
at) or a list of XLib API's I need call?

Regards,
- Graeme -

Look at XShapeCombineMask()

Also, the Xmu libraries have done this; see XmuReshapeWidget()
