Yes, it is bad to inherit from more than one UI. You had a QDialog andf a QMainWindow. They have to different event handlers, etc... So it is not ok .Also, you were always adding items to the same tree widget.

I modified a little bit your code and attached it.

You always must pass the tree widget which handled the context menu event.
Hey, didn't you said you have three tree widgets? I only saw one in the ui's...

Hey, I got it working!

Yes, but I only wanted to get a working example of it. Now I have implemented it in my project

So.. thanks marcel, you rule! This has been a nice welcome to the qtcentre forums for me. See you.
