1 - What is the QMainWindow Class ?

The QMainWindow class has been specially designed to manage the main window of your application when it is complex. Among the features offered to us by the QMainWindow class, we find in particular the menus, the toolbar and the status bar. The QMainWindow class inherits directly from QWidget. It is a widget that is generally used once per program and is only used to create the main window of the application.

Note:

Simple pyqt applications won't need to use the QMainWindow class, they just use the QWidget class.

If Condition
---  Run this part ---
Else
--- Perform this other part ---
End if
