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
Python3
# importing librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# checking if active window# outside the classcheck = window.calendar.isActiveWindow()print("Active window : " + str(check))# start the appsys.exit(App.exec()) |
Output :
Active window : True
