In this article we will see how we can set the auto repeat delay time of the QCommandLinkButton.It defines the initial delay in milliseconds before auto-repetition kicks in. In auto repeat property the pressed
, released
, and clicked
signals are emitted at regular intervals when the command link button is down. Auto repeat property is off by default although it can be enabled with the help of setAutoRepeat
method.
In order to do this we use setAutoRepeatDelay
method with the command link button object
Syntax : button.setAutoRepeatDelay(n)
Argument : It takes integer as argument
Return : It return 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 command link button
cl_button = QCommandLinkButton( "Press" , self )
# setting geometry
cl_button.setGeometry( 250 , 100 , 200 , 50 )
# setting auto repeat
cl_button.setAutoRepeat( True )
# setting delay time
cl_button.setAutoRepeatDelay( 1000 )
# creating label
label = QLabel( "GeeksforGeeks" , self )
# setting label geometry
label.setGeometry( 50 , 100 , 200 , 40 )
# counter
self .counter = 0
# adding action to the button
cl_button.clicked.connect( lambda : update_label())
# method for updating label text
def update_label():
# setting label text
label.setText( str ( self .counter))
# incrementing the counter
self .counter + = 1
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
