Hi, First, thanks for your answers :) But I didn't ask the good question : in fact, I'd like to overlap a video output widget and a Mozilla gecko widget. I want to put the browser on top of the video output, so you can see the video through the brower. In a word, the browser should be transparent. I know this is possible to do such things when the video widget works with framebuffer. Some poeple did such things with DirectX already, and I'm looking for a way to do it with GTK.
