In this article we will see how we can get signal when time of the QDateTimeEdit widget changes. QDateTime is basically a combination of QDate and QTime i.e it has both date and time. And QDateTimeEdit widget is used to show or receive the QDateTime. We can set QDateTime to it with the help of setDateTime method. Setting time will not affect the date of the QDateTimeEdit, it can be set with the help of setTime method.

In order to do this we will use timeChanged method with the QDateTimeEdit object.

Syntax : datetimeedit.timeChanged.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):
        # setting title
        self.setWindowTitle("Python ")
        # setting geometry
        self.setGeometry(100, 100, 500, 400)
        # calling method
        # showing all the widgets
    # method for components
    def UiComponents(self):
        # creating a QDateTimeEdit widget
        datetimeedit = QDateTimeEdit(self)
        # setting geometry
        datetimeedit.setGeometry(100, 100, 150, 35)
        # setting date time to it
        datetimeedit.setDateTime(QDateTime(2020, 10, 10, 11, 30))
        # time
        time = QTime(21, 45)
        # setting only time
        # creating a label
        label = QLabel("GeeksforGeeks", self)
        # setting geometry to the label
        label.setGeometry(100, 160, 200, 60)
        # making label multi line
        # getting current time
        value = datetimeedit.time()
        # setting text to the label
        label.setText("Time : " + str(value))
        # getting time change signal
        datetimeedit.timeChanged.connect(lambda: label.setText("Time Change signal Emitted"))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
