Thanks for that, but as usual for one answer there come more questions :-)

When I install an eventfilter on the textBrowser I get many events like 
ToolTip but very few MouseMoves. In fact I get only MouseMove events 
immediately after the mouse enters or before it leaves the textBrowser. 

Funny is that I get MouseButtonDblClick events with the middle and right 
button but not with the left button.

In contrast to that, when I use a sub-class of textBrowser I think I get 
all MouseMove events, but sub-classing objects, when I use the designer is 
somewhat - hm, ugly - because you don't see it in designer.
