thanks for all advice. As mentioned before in this list by another smart one, 
a conveniend way was this: 
in designer i generate a custom widget with class QHBox and policy 'expanding' 
and then use it as a placeholder. My final signal/event catching widget is 
constructed 'by hand' as child of this placeholder. This works out fine for 

Been three days to this list and got two problems solved - really great!
