Hi again...

I'm sorry but I didn't understand your answer.

I know that. My question is if the GtkDrawingArea will raster
images on the server side when using GdkPixMaps.

I'm sorry if i messed things up here a bit. I should have asked
"If the DrawingArea uses only a GdkWindow I guess..." not GdkScreen.

The question here was:

Is the GtkDrawingArea using a GdkWindow internaly or is it using
a client side image representation for some implementation reasons?

Where by client side image I refer to a GdkRGB or maybe GdkPixBuf.
