[Qt-interest] Handling mouse events in soft-realtime case

[Oliver Demetz]

Well,
your right, as long as you are still in your paint event, no new event 
can be taken into account.
But then the point to tune your app is your paint event, which has to 
become faster. Think about which parts of your painting can be cached 
st. they dont cost computation time in every event.

Regards,
Oliver
