PyQt5 QDateEdit – Date Changed Signal

In this article we will see how we can get date changed signal of the QDateEdit. Date change signal occurs when date of the date-edit gets changed, user can change the date with the help of cursor or the keyboard also we can programmatically set date to it with the help of setDate method.

In order to do this we use dateChanged method with the QDateEdit object

Syntax : date.dateChanged.connect(method)

Argument : It takes method as argument

Return : It returns None

Below is the implementation

# importing libraries

from PyQt5 import QtCore, QtGui

import sys


class Window(QMainWindow):

    def __init__(self):
        super().__init__()

        # setting title
        self.setWindowTitle("Python ")

        # setting geometry
        self.setGeometry(100, 100, 500, 400)

        # calling method
        self.UiComponents()

        # showing all the widgets
        self.show()

    # method for components
    def UiComponents(self):

        # creating a QDateEdit widget
        date = QDateEdit(self)

        # setting geometry of the date edit
        date.setGeometry(100, 100, 150, 40)

        # creating a label
        label = QLabel("GeeksforGeeks", self)

        # setting geometry
        label.setGeometry(100, 150, 200, 60)

        # making label multiline
        label.setWordWrap(True)

        # date  change signal
        date.dateChanged.connect(lambda: method())

        # method called when signal emitted
        def method():

            # setting text to the label
            label.setText("Date  Changed Signal")



# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :
