PyQt5 QCommandLinkButton – 获取自动重复属性

在本文中，我们将了解如何获取 QCommandLinkButton 的自动重复属性。如果启用了自动重复属性，则当命令链接按钮关闭时，将定期发出pressed 、 released和clicked信号。自动重复属性默认关闭。初始延迟和重复间隔由autoRepeatDelay和autoRepeatInterval方法以毫秒为单位定义。可以借助setAutoRepeat方法将此属性设置为命令链接按钮。

为了做到这一点，我们使用带有命令链接按钮对象的autoRepeat方法

Syntax : button.autoRepeat()

Argument : It takes no argument

Return : It return bool

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)
  
        # creating label
        label = QLabel("GeeksforGeeks", self)
  
        # setting label geometry
        label.setGeometry(100, 100, 200, 40)
  
        # getting auto repeat property
        value = cl_button.autoRepeat()
  
        # setting text to the label
        label.setText("Auto Repeat : " + 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())
