GdkOffscreenWindow and texture_from_pixmap extension

[Juan Pablo Ugarte <juanpablougarte gmail com>]

Hello everyone.

I want to do some OpenGL widget compositing using GtkGLExt and
GdkOffscreenWindow.

I implemented a offscreen widget as the ones in gtk-demo to be able to
use the offscreen GdkPixmap as the source for a texture.


But I am having some problems while trying to bind the GdkPixmap to the texture

So does anyone know how to ge a Pixmap, as returned by
XcompositeNameWindowPixmap(), from a GdkOffscreenWindow in order to
use it in glxCreatePixmap()?


thanks
