hi,
Generally these types of error comes, when u are updating/painting gui widget
in non-gui thread. Are u updating QTreeWidget in user defined thread?????If
yes, then don't do that, it will mess...Update the widget in non-gui thread
is possible, by sending the customevent and make it in customevent slot...
Thanks and Regards,
Niranjan.

Hi,
Thanks for response
My application has only one thread. I am getting these errors when I am
trying to scroll QTreeWidget. My application also has QTableWidget and
it is not showing any such type of errors while scrolling.
Below is screen shot of my QTreeWidget.
Have any other clue?????
Thanks,
Vijay Mehta
