PyQt5 QCommandLinkButton – 设置自动重复延迟时间

在本文中，我们将看到如何设置 QCommandLinkButton 的自动重复延迟时间。它定义了在自动重复开始之前的初始延迟（以毫秒为单位）。在自动重复属性中，以固定间隔发出pressed 、 released和clicked信号当命令链接按钮关闭时。自动重复属性默认是关闭的，尽管它可以在setAutoRepeat方法的帮助下启用。

为了做到这一点，我们使用setAutoRepeatDelay方法和命令链接按钮对象

Syntax : button.setAutoRepeatDelay(n)

Argument : It takes integer as argument

Return : It return None

下面是实现

# 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())
