Hi,
I found a way around it by trial and error....
It turned out to be the operation len(<list>) , where the <list> was a
list of graphics items caused the problem when used in mouseReleaseEvent .
In this case it was possible to change the code achieving the same result
but not using the len() method.
Not sure if this helps in finding the problem.

Hi,
I have been expanding my code with new features after which I experience
an error
NotImplementedError: QGraphicsItem.boundingRect() is abstract and must be
overridden
when using the rubber band. The procedure has been working before, but
obviously I disturbed the devil.
Any suggestions on what to change or do to get rid of the problem
Cheers, Heinz
Can you produce a test case that demonstrates the problem?
