Some menubar items can not be clicked

[richardander]

Thank you so much for the prompt help!

I did it and same problem exists. Attached is the screenshot.

BTW, in the existing code , the mainwindow and menu were designed in designer and compiled with UIC. But I tried the in your way by using addMenu of menubar. The same probelms happend only to the first three menu items. After the first three, everything is OK.

Can you guess what the gray bar in the Qt3.3 implementation is? Or give me some clue what are the ways to create it so that I can search the code.

Thank you again!
