PyQt5 QCommandLinkButton – 获取自动重复间隔时间
在本文中,我们将了解如何获取 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。可以借助 setAutoRepeatDelay 方法设置间隔时间。
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
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(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())
