In this article, we will see how we can set the auto-repeat interval time of the QCommandLinkButton.It defines the length of the auto-repetition interval in milliseconds when auto repeat property is enabled. 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
Python3
# importing librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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 interval time 500 milliseconds cl_button.setAutoRepeatInterval(500) # creating label label = QLabel("neveropen", self) # setting label geometry label.setGeometry(100, 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 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
