PyQt5 QCommandLinkButton – 设置自动重复属性
在这篇文章中,我们将看到如何设置QCommandLinkButton的自动重复属性。如果自动重复属性被启用,那么当命令链接按钮下降时,按压、释放和点击的信号会以一定的间隔发出来。默认情况下,自动重复属性是关闭的。初始延迟和重复间隔由autoRepeatDelay和autoRepeatInterval方法以毫秒为单位定义。
为了做到这一点,我们使用命令链接按钮对象的setAutoRepeat方法。
语法: button.setAutoRepeat(True)
参数: 它以bool作为参数
返回: 它返回无。
下面是实现方法
# 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)
# 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())
