In this article we will see how we can get 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 time of date edit is changed.
In order to do this we use timeChanged
method with the QDateEdit object
Syntax : date.timeChanged.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( "GeeksforGeeks" , self )
# setting geometry
label.setGeometry( 100 , 150 , 200 , 60 )
# making label multiline
label.setWordWrap( True )
# time change signal
date.timeChanged.connect( lambda : method())
# method called when signal emitted
def method():
# setting text to the label
label.setText( "Time Changed Signal" )
# date time
time = QTime( 11 , 20 , 0 )
# setting time
date.setTime(time)
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
