How gtk say to DirectFB that > the image is over the video? I guess that your code creates a GtkWidget derived from GtkDrawingArea and uses an IDirectFBVideoProvider to draw on the widget's window's DirectFB surface. Is that right? To draw on the video, you'd have to draw the image to the video surface in the callback just before you do the flip. You can use DirectFB draw methods on the surface or access the widget->window by means of GDK functions. A GtkImage is not well suited for this task since it has it's own window and drawing routines. You probably want to use a GdkPixbuf or a GdkImage instead. Salut, Sven -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe directfb-users" as subject.
