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( "GeeksforGeeks" , 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 ())
