Is the mouse tracking and paintEvent catching and the like needed at all?
I think that a simple call to item's setToolTip that your are indeed calling 
should suffice:


I think that the problem is that you are using column 1 instead of 0 that is 
the visible one. Note that column 1 is hidden and is used to store the actual 
key of the processing.
