  • Last Updated : 07 Jul, 2020

In this article we will see how we can get date time changed signal of the QDateEdit. Unlike normal like date we can set date time to it with the help of setDateTime method. But also we can set only time as well without changing the date with the help of setTime method. This signal is emitted whenever the date time of date edit is changed.

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

Syntax : date.dateTimeChanged.connect(method)

Argument : It takes method as argument

Return : It returns None

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, 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 time change signal
        date.dateTimeChanged.connect(lambda: method())
  
        # method called when signal emitted
        def method():
  
            # setting text to the label
            label.setText("Date Time Changed Signal")
  
  
        # date time
        time = QDateTime(2020, 10, 10, 9, 30)
  
        # setting time
        date.setDateTime(time)
  
  
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
