In this article we will see how we can get the title changed signal from the QCalendarWidget. Title changed signal is emitted when the calendar’s title i.e caption has changed. Setting title also emit the same signal.
In order to do this we will use windowTitleChanged method with the QCalendarWidget object.
Syntax : calendar.windowTitleChanged.connect(lambda: print(“Title Changed”))
Argument : It takes no argument
Action Performed : It will print the message whenever signal get emitted
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 calendar = QCalendarWidget(self) # setting geometry to the calendar calendar.setGeometry(10, 10, 400, 250) # creating a label label = QLabel(self) # setting geometry to the label label.setGeometry(100, 280, 250, 60) # making label multi line label.setWordWrap(True) # text text = "Title Changed Signal Emitted" # getting the title changed signal and # when receives the signal printing the message calendar.windowTitleChanged.connect(lambda: label.setText(text)) # setting caption to the calendar calendar.setWindowTitle("Title")# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
