Maybe problem is for 'typGraphics *g' in expose_Event(..) but for generic
'gpointer g' I have not solution...

Yes, it looks like that ('g' or 'g->pixmap' is/are probably the source of your problem). From the sample you've posted it's unclear how you allocate and fill a 'typGraphics' structures. You have to do this in "configure-event" callback.
