[Qt-interest] tooltips

[phil prentice]

After further investigation I realised that I was getting setStatusTip() 
confused with setToolTip().  Sorry for wasting peoples time.  I also realised 
that if wanted to display the tooltips in a different widget rather then as a 
balloon that I could I assume use an eventfilter() to achieve this by using 
the event filter to catch the helpEvents and redisplaying them in the widget.  
At the moment I will see how I get on with the balloons.

Thanks
Phil
