title: Is it possible to add a menu bar to a widget
body: <p>I would like to add a QMenuBar to a window of my program (not the QMainWindow) from QtDesigner but I do not see this widget in there and it seems the only way to do this from designer is to use a mainwindow.  Would I absolutely need to create this QMenu by hand coding it.  Is it possible/ok to instead add a QMainwindow that is actually declared inside my main QMainwindow?</p>
