That is true. The order of the events when the drawing area is displayed
the first time, is 'configure_event' and then 'realize'.
The simple.c example shows the same behavior so i think it's not my
fault.

The problem is solved. After working on it for some hours i got it. 
now i have the simple.c in my code and working :-) juhu
Even a zoom ability (mouse wheel) is already implemented.
