PyQt5 QCalendarWidget – Setting Leave Event
  • Last Updated : 15 Jun, 2020

In this article we will see how we can implement the leave event for the QCalendarWidget. A leave event is sent to the calendar when the mouse cursor leaves the calendar. This event handler can be reimplemented in a subclass to receive calendar leave events which are passed in the event parameter.

Below is the Calendar class code

# QCalendarWidget Class
class Calendar(QCalendarWidget):
    
    # constructor
    def __init__(self, parent=None):
        super(Calendar, self).__init__(parent)

    # overriding the leave event
    def leaveEvent(self, event):

        # setting to the text to the label
        window.label.setText("Leave Event Take place")

Implementation steps:
1. Create a Calendar class that inherits the QCalendarWidget
2. Inside the Calendar class override the leaveEvent and inside the event set the text to the label
3. Create a main window class
4. Create a Calendar object inside the main window
5. Set various properties to the calendar

Below is the implementation




# importing libraries
from PyQt5.QtWidgets import * 
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import * 
from PyQt5.QtCore import * 
import sys
  
# QCalendarWidget Class
class Calendar(QCalendarWidget):
    def __init__(self, parent = None):
        super(Calendar, self).__init__(parent)
  
    # overriding the leave event
    def leaveEvent(self, event):
  
        # setting to the text to the label
        window.label.setText("Leave Event Take place")
  
  
class Window(QMainWindow):
  
    def __init__(self):
        super().__init__()
  
        # setting title
        self.setWindowTitle("Python ")
  
        # setting geometry
        self.setGeometry(100, 100, 650, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
    # method for components
    def UiComponents(self):
  
        # creating a QCalendarWidget object
        # as Calendar class inherits QCalendarWidget
        self.calendar = Calendar(self)
  
        # setting geometry to the calender
        self.calendar.setGeometry(50, 10, 400, 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)
  
        # setting text to the label
        self.label.setText("No Event")
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
