I donβt think you can make the menu bar appear at the bottom of the screen. However, you can:
1) use the built-in menuBar () function to get the real menu bar and customize the menu the way you need your native OS (e.g. symbian).
2) create your own menu bar by simply creating a QHBoxLayout and adding buttons to it that create a popup menu. When you are done, it will look very much like a menu bar. You most likely want to play with button layout mockups.
