PyQt5 QCommandLinkButton - 设置自动重复间隔时间

在本文中，我们将看到如何设置 QCommandLinkButton 的自动重复间隔时间。它定义了启用自动重复属性时自动重复间隔的长度（以毫秒为单位）。在自动重复属性中，当命令链接按钮关闭时，会定期发出按下、释放和单击信号。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

Python3

# 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 interval time 500 milliseconds
        cl_button.setAutoRepeatInterval(500)
 
        # creating label
        label = QLabel("GeeksforGeeks", 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 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())
