okay, this wasn't clear to me. 
I first assumed that it would have been enough to simply initialise
the tile with some pixmap (gdk_gc_set_tile()). I didn't know
that an explicit (gdk_gc_set_fill()) was required. Many thanks.

The previous method worked fine for me. But just curiosity, 'cause
I didn't find the exact documentation of how to set backgrounds,
could you give me an example perhaps? 
How to set an image as background image on a drawingboard?

Learning all the time,
