This code example creates a skeleton of a classic GUI application with a menubar, toolbar, and a statusbar.
textEdit = QtGui.QTextEdit() self.setCentralWidget(textEdit)
Here we create a text edit widget. We set it to be the central widget of the QtGui.QMainWindow
. The central widget occupies all space that is left.
