[Qt-interest] Problem with QParallelAnimationGroup

[Bo Elmgreen]

Hi,

I have a problem with QParallelAnimationGroup that I hope that someone 
can help me with. I am using a slightly modified version of this example:
http://www.developer.nokia.com/Community/Wiki/Code_Example_for_SlidingStackedWidget_class_in_Qt
to make sliding animations between pages in my application (using Qt 
4.6.3 on Symbian 3rd Ed FP2, i.e. a C5). Normally it works fine and the 
performance is ok, but if for some reason the animation is interrupted, 
I cannot get it to work again. If the animation is interrupted, I never 
receive the finished() signal and it appears as though the animation is 
running forever. Even if I try to delete the old animation group and 
create a new one and start it, it appears to start but it is not running 
(it never emits the finished() signal)??? A clip from my traces follows 
below.

Any ideas as to how I can solve this problem would be highly appreciated!

Best Regards,
Bo Elmgreen
