Toolbar
Menus group all commands that we can use in an application. Toolbars provide a quick access to the most frequently used commands.

In the above example, we create a simple toolbar. The toolbar has one tool action. An exit action which terminates the application when triggered.
exitAction = QtGui.QAction(QtGui.QIcon('exit24.png'), 'Exit', self) exitAction.setShortcut('Ctrl+Q') exitAction.triggered.connect(QtGui.qApp.quit)
Similar to the menubar example above, we create an action object. The object has a label, icon and a shorcut. A quit()
method of the QtGui.QMainWindow
is connected to the triggered signal.
self.toolbar = self.addToolBar('Exit') self.toolbar.addAction(exitAction)
Here we create a toolbar and plug and action object into it.
