PyQt5 QCalendarWidget – Setting Mouse Move Event

  • Last Updated : 17 Jun, 2020

In this article we will see how we can implement the mouse move event for the QCalendarWidget. This event handler, for event event, can be reimplemented in a subclass to receive mouse move events for the widget. If mouse tracking is switched off, mouse move events only occur if a mouse button is pressed while the mouse is being moved. If mouse tracking is switched on, mouse move events occur even if no mouse button is pressed.

Implementation steps:
1. Create a Calendar class that inherits the QCalendarWidget
2. Create alabel to show the updates
3. Override the mouseMoveEvent and set the position to the label
4. Create a Calendar object inside the main window
5. Set various properties to the calendar

        # creating a QCalendarWidget object
        # as Calendar class inherits QCalendarWidget
        self.calendar = Calendar(self)
  
        # turing on the mouse tracking
        self.setMouseTracking(True)
  
        # setting geometry to the calender
        self.calendar.setGeometry(50, 10, 250, 250)
  
        # setting cursor
        self.calendar.setCursor(Qt.PointingHandCursor)
  
        # creating label to show the properties
        self.label = QLabel(self)
  
        # setting geometry to the label
        self.label.setGeometry(100, 280, 250, 60)
  
        # making label multi line
        self.label.setWordWrap(True)
  
    def mouseMoveEvent(self, event):
        self.label.setText('coords: ( % d : % d )' % (event.x(), event.y()))
  
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
