In this case, regrettably i'm using Qt4, and there are no longer these
event-classes, i for one doesn't see them.
I found some examples, but they all use the customevent stuff.
So I have to dig deeper in the qt4-bibs.
So you have not another hint because of that you does not use
the qt4 port ?

Oh yes, in this case I know that. I'll try several general possibilties
to get the overall
understanding.
So back to to the drawing table...

cheers.
