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("neveropen", 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()) |
Output :
