Okay, now I understand the problem. But are you really sure that nothing at all is displayed? Not even a tiny empty rectangle (the actual menu with no items in it)? And I mean really small, like a few pixels in height... this would indicate that the changes you did in Qt Creator - adding the menu items - are not reflected in either the *.ui file (you did not save) or the generated files (they are not re-generated or compiled/linked).

Also, are you sure you are not mixing up your debug/release binaries? Maybe you are building in release mode, but are starting the (outdated) debug binary?

Anyway, I still assume that after you did your changes in Qt Creator that the resulting files are not properly auto-generated. Are you using qmake? I strongly assume so (since you mentioned Qt Creator). Make sure that in your *.pro file the UI files are proplery declared:

FORMS += YourMainWindow.ui

qmake then takes care of the necessary steps (uic'ing, moc'ing). Do a 'make clean' (or in Qt Creator: right-click on the project(s) and "Clean") and see if that makes a difference...

Cheers, Oliver
