In this article we will see how we can check if the QCalendarWidget is visible to its ancestor. In order to do this we use isVisibleTo method. This method returns true if the calendar would become visible if ancestor is shown; otherwise returns false. The true case occurs if neither the calendar itself nor any parent up to but excluding ancestor has been explicitly hidden.
In order to do this we will use
isVisibleTomethod with the QCalendarWidget object.Syntax : calendar.isVisibleTo(parent)
Argument : It takes QWidget object as argument
Return : It return bool
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 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 calendar 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) # checking if the calendar is visible to main window value = self.calendar.isVisibleTo(self) # setting text to the label self.label.setText("Visible to main window : " + str(value)) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output:
