Menus and toolbar

Question

I am new in programming and I have created a simple application with one class in Python and PySide which manipulates phone bill csv files. Now I want an option for mobile too.

How can I add a menubar, when my class inherits from QWidget? Should I write another class which inherits from QMainWindow and then make an instance of my first class as a central widget? Is this the right way to do this?

class MyWidget(QtGui.QWidget):

    def __init__(self, parent=None):
        super(MyWidget, self).__init__(parent)
        ....


class MyWindow(QtGui.QMainWindow):

    def __init__(self, parent=None):
        super(MyWindow, self).__init__(parent)

        widget = MyWidget()
        self.setCentralWidget(widget)
        ...

There's no need for a QMainWindow, you can simply create a QMenuBar in your widget.

class MyWidget(QtGui.QWidget):
    def __init__(self, parent=None):
        super(MyWidget, self).__init__(parent)
        self.menu=QtGui.QMenuBar()
        self.menu.addAction("do something")
        layout=QtGui.QVBoxLayout()
        layout.addWidget(self.menu)

A QMainWindow is basically a widget which already has a layout with a menu bar, a toolbar, a status bar, etc. If you don't need all of those functionality, you can use a simple QWidget and add only what you want.
