I have write a application in which user can add QToolButtoninto the UI dynamic. But there is something wrong seriously with my application.
It often crashes!!
The following is what I get from the DOS output:

H:/QTprojects/testdynamic/debug/testdynamic.exe exited with code 1073807364
in which testdynamic.exe is the application I write.
Do some guys know the reason?
Thanks a lot!
