In this article we will see how we can get signal when only date 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 date will not affect the time of the QDateTimeEdit, it can be set with the help of setDate method.
In order to do this we will use dateChanged method with the QDateTimeEdit object.
Syntax : datetimeedit.dateChanged.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) # setting date time to it datetimeedit.setDateTime(QDateTime(2020, 10, 10, 11, 30)) # date date = QDate(2020, 1, 1) # setting only date datetimeedit.setDate(date) # 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) # getting current date value = datetimeedit.date() # setting text to the label label.setText("Date : " + str(value)) # getting date change signal datetimeedit.dateChanged.connect(lambda: label.setText( "Date Change signal Emitted")) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
