I mean that I can add actions and menus and all is as expected.

Well, normally when I have a menu I expect to see all the items when I click 
on it. I cannot click on an item because they doesn't appear when I click on 
the menu. The signal/slots are connected from the source code (from a class) 
not in the designer.

I'm not familiar with this technology I don't think I need it at the moment. 
However, it will be a good feature...

BTW, when I construct menu with actions from the source code it works fine. 
When I create the same from the designer it doesn't.
