Title: business
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.
Cheers, Heinz

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
