User-defined slots for menu pyqt4

According to what I know, Qt Designer is unable to work with signal/slot handling(a slot defined by me). Do you have documentation for user-defined slots for menus?

  1. I use PyQt
  2. Other widgets are able to define user-defined slots

Question: How can I define my own slot for a menu?

Solution

  • If you are asking how to make user-defined slots for menus in Qt, something like this should work:

    Add a QAction to the menu item, and connect the action's triggered signal to a slot.

    class Example(QtGui.QMainWindow):

    def __init__(self):
        super(Example, self).__init__()

        self.initUI()

    def initUI(self):
        testAction = QtGui.QAction(QtGui.QIcon('test.png'), '&Exit', self)
        testAction.triggered.connect(self.runExample)
        menubar = self.menuBar()
        testMenu = menubar.addMenu('&Test')
        testMenu.addAction(testAction)

    def runExample(self):
        print "Running example."
