Apologies for the double post but I thought this was relevant.

Hi Renato,

It seems to me that using non-rectangular widgets is one possible technique
for creating a Winamp-style (Winamp 3, by the way, not Winamp 2!) skinning
engine. The other possibility that comes to mind is partial window
transparency. Perhaps there are others.

Thanks for the hint. I think I recall reading something about the compose
method, so I'll go back and read it more closely. I have been having trouble
with the classes Gtk::Pixmap, Gdk::Pixbuf and Gtk::Bitmap. I'm sure there's
a way to load a background image, load a mask image, combine the two and
store the result in a Gdk::Window, but I haven't found the right API calls
yet.

Cairo could make some interesting "art deco" type widgets, buttons and the
like. Isn't it just for vector drawing, though? I want to load and mask
raster images.

Regards,
Adam J Richardson
