PyQt5 QCalendarWidget – Releasing Grabbed Mouse Input

  • Last Updated : 09 Jun, 2020

In this article we will see how we can ungrab i.e releasing the mouse input for the QCalendarWidget. By grabbing mouse the calendar will not be affected, except that it doesn’t receive any mouse events. setFocus moves the focus as usual, but the new focus widget receives mouse events only after releaseMouse is called. We can grab the mouse with the help of grabMouse method .

In order to do this we will use releaseMouse method with the QCalendarWidget object.

Syntax : calendar.releaseMouse()

Argument : It takes no argument

Return : It return None

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
  
  
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
        self.calendar = QCalendarWidget(self)
  
        # setting geometry to the calender
        self.calendar.setGeometry(50, 10, 400, 250)
  
        # setting cursor
        self.calendar.setCursor(Qt.PointingHandCursor)
  
        # grabbing mouse input
        self.calendar.grabMouse()
  
        # releasing mouse input
        self.calendar.releaseMouse()
  
          
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

Output :
Both mouse and keyboard inputs are working
