PyQt5 QCommandLinkButton – 获取自动重复延迟时间

在本文中，我们将了解如何获得 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， pressed 、 released和clicked信号定期发出命令链接按钮关闭时的间隔。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。可以借助setAutoRepeatDelay方法为命令链接按钮设置延迟时间。

为了做到这一点，我们使用带有命令链接按钮对象的autoRepeatDelay方法

Syntax : button.autoRepeatDelay()

Argument : It takes no argument

Return : It return integer

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)
  
        # getting auto repeat delay time
        value = cl_button.autoRepeatDelay()
  
        # setting text to the label
        label.setText("Auto Repeat Delay (ms) : " + str(value))
  
        # 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())
