PyQt5 QCommandLinkButton – 获取自动重复的延迟时间
在这篇文章中,我们将看到如何获得QCommandLinkButton的自动重复延迟时间。它定义了自动重复启动前的初始延迟,单位是毫秒。在自动重复属性中,当命令链接按钮下降时,按压、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。在setAutoRepeatDelay方法的帮助下,可以为命令链接按钮设置延迟时间。
为了做到这一点,我们使用命令链接按钮对象的autoRepeatDelay方法。
语法 : button.autoRepeatDelay()
参数: 它不需要参数
返回: 返回整数
下面是实现方法

class Window(QMainWindow):
def __init__(self):
super().__init__()

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())
