Removing divider between menubar and rest of main window

Im using Qt 4.4.3 on windows.. My ui was built in designer.. How do I remove the divider thats between the menubar and the rest of the main window?

I attached an image and circled in red what I want to remove..

Thats default behaviour I guess... it appears everywhere in menus

I have examples of other programs(not sure what language they are written in) that do not have this divider in them..

So modify the style your application uses and make sure the bevel is not drawn. As far as I know and remember that's what menu bars used to look like on "old" windows installations.

Hi,

You may play with the border properties of the menubar. It could also be useful.
