After upgrading Ubuntu 9.10 to 10.04 I encounter some problems with
running a graphics application I built last year. It uses the mechanisms
described in the example "elasticnodes". The two application represent a
graph, which when moving the nodes also update the location of the arcs.
In both cases the arcs are not updated. In fact the example does not
show the arcs when starting it. My application does show the arcs, but
it does not update. I dug for some hours in the code, but could not find
a problem. It seems it does not get into the "itemChange" method of the
"QGraphicsItem" class. Some manipulations resulted in abortion of the
task, which when running from within Eclipse did not produce an error
message. From the terminal I got an occasional segmentation fault.
Has somebody experienced similar problems?
I should mention that I upgraded Ubuntu and did not do a clean
re-install just as yet. I guess that would be the next step.
