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("neveropen", 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()) |
Output :
