In this article, we will see how we can check if the QCalendarWidget is an active window. An active window is a visible top-level window that has the keyboard input focus. Making it an active window will set the top-level widget containing this calendar to be the active window. We can make it an active window with the help of activateWindow method.
Note: This method should be called outside the main window class else it will always return false
In order to do this we will use isActivateWindow method with the QCalendarWidget object.
Syntax : calendar.isActivateWindow()
Argument : It takes no argument
Action Performed : It return bool
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 , 600 , 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 calendar
self .calendar.setGeometry( 10 , 10 , 400 , 250 )
# setting name
self .calendar.setAccessibleName( "Geek Calendar" )
# making it an active window
self .calendar.activateWindow()
# creating a label
label = QLabel( self )
# setting geometry to the label
label.setGeometry( 100 , 280 , 250 , 60 )
# making label multi line
label.setWordWrap( True )
# checking active window
value = self .calendar.isActiveWindow()
# setting text to the label
label.setText( "Active Window(Checking inside the class) " + str (value))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# checking if active window # outside the class check = window.calendar.isActiveWindow()
print ( "Active window : " + str (check))
# start the app sys.exit(App. exec ())

Output :
Active window : True
