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.
