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.
