    import sys
    from PyQt4 import QtGui
    
    
    class Example(QtGui.QMainWindow):
        
        def __init__(self):
            super(Example, self).__init__()
            
            self.initUI()
            
            
        def initUI(self):               
            
            exitAction = QtGui.QAction(QtGui.QIcon('exit24.png'), 'Exit', self)
            exitAction.setShortcut('Ctrl+Q')
            exitAction.triggered.connect(QtGui.qApp.quit)
            
            self.toolbar = self.addToolBar('Exit')
            self.toolbar.addAction(exitAction)
            
            self.setGeometry(300, 300, 300, 200)
            self.setWindowTitle('Toolbar')    
            self.show()
            
            
    def main():
        
        app = QtGui.QApplication(sys.argv)
        ex = Example()
        sys.exit(app.exec_())
    
    
    if __name__ == '__main__':
        main()
    

    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.
