GtkWindow and XShape

["Alexandre Moreira" <alexandream gmail com>]

Hey there, guys.

Is there a way to put a shape mask on a GtkWindow  (I'm trying to
achieve rounded corners on a window that has no WM decoration) ? I've
been trying to test it with gdk_window_shape_combine_mask but I had no
success so far...

If it is possible, is there any doc I can read ? Or can anyone give me
a few hints on how to get started on this ?

Thanks,
Alexandre Moreira.
