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( "GeeksforGeeks" , 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 ())
