PyQt5 QCalendarWidget – Setting Mouse Release Event

In this article we will see how we can implement the mouse release event for the QCalendarWidget. This event handler, for event, can be reimplemented in a subclass to receive mouse release events for the calendar.

Below is the Calendar class code

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

    # overriding the mouseReleaseEvent method
    def mouseReleaseEvent(self, event):
        print("Mouse Release Event")

Implementation steps:
1. Create a Calendar class that inherits the QCalendarWidget
2. Inside the Calendar class override the mouseReleaseEvent and inside the event print the text
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

Python3

# 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):

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

    # overriding the mousePressEvent method
    def mousePressEvent(self, event):
        print("Mouse Press Event")

    # overriding the mousePressEvent method
    def mouseReleaseEvent(self, event):
        print("Mouse Release Event")





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 calendar
        self.calendar.setGeometry(50, 10, 400, 250)

        # setting cursor
        self.calendar.setCursor(Qt.PointingHandCursor)



# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :

Mouse Press Event
Mouse Release Event
Mouse Press Event
Mouse Release Event
Mouse Press Event
Mouse Release Event
