PyQt5 QCommandLinkButton – 获取自动重复间隔时间

在这篇文章中，我们将看到如何获得QCommandLinkButton的自动重复间隔时间。它定义了自动重复属性启用时自动重复间隔的长度，单位是毫秒。在自动重复属性中，当命令链接按钮下降时，按下、释放和点击的信号会以固定的时间间隔发出。自动重复属性默认是关闭的，尽管它可以在setAutoRepeat方法的帮助下被启用。间隔时间可以在setAutoRepeatDelay方法的帮助下设置。

为了做到这一点，我们在命令链接按钮对象中使用autoRepeatDelay方法。

语法： button.autoRepeatDelay()

参数： 它不需要参数

返回： 它返回整数

下面是实现方法

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(50, 100, 200, 40)
 
        # getting auto repeat interval
        value = cl_button.autoRepeatInterval()
 
        # setting text to the label
        label.setText("Auto Repeat Interval (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())
