When I use segmentEditor paint I find LeftButtonPressEvent is not triggered.  
How do I get LeftButtonPressEvent when I use segmentEditor paint.  
Think you!

Probably the segment editor consumes the event. If you want to intercept the event before the segment editor gets it, you can add an observer with a higher priority.
