In this article we will see how we can get QDateTime changed signalof the QDateTimeEdit widget. 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.
This signal is emitted when there is a change in the QDateTime
In order to do this we will use dateTimeChanged method with the QDateTimeEdit object.
Syntax : datetimeedit.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 QDateTimeEdit widget datetimeedit = QDateTimeEdit(self) # setting geometry datetimeedit.setGeometry(100, 100, 150, 35) # creating a label label = QLabel("neveropen", self) # setting geometry to the label label.setGeometry(100, 160, 200, 60) # making label multi line label.setWordWrap(True) # datetime changed signal when emitted connect to the # dt_method every time datetimeedit.dateTimeChanged.connect(lambda: dt_method()) # method called by the datetime def dt_method(): # getting current datetime value = datetimeedit.dateTime() # setting text to the label label.setText("New DateTime : " + str(value)) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
