Menubar position and orientation

It would be nice if QMainWindow had something like this:

class QMainWindow {
...

enum MenuBarPosition

;

void setMenuBarPosition(MenuBarPosition mp);
MenuBarPosition menuBarPosition() const;
};

and

class QMenuBar {
...
Qt::Orientation orientation() const;
void setOrientation(Qt::Orientation o);
};

As an example you might want to have a look at Microsoft Office 2003. (i.e.Word 2002).
The menu behaves like a dockwindow. It can be placed top/bottom/left or right. If left or right, it also rotates the text.
