PyQt5 QCommandLinkButton – 下载属性

在本文中,我们将了解如何获取 QCommandLinkButton 的属性。 Down 属性保存命令链接按钮是否被按下。如果此属性为 true,则按下按钮。如果我们将此属性设置为 true,则不会发出pressedclicked的信号。默认情况下,此属性为 false。我们可以在setDown方法的帮助下设置这个属性。

为了做到这一点,我们使用isDown方法和命令链接按钮对象

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 down property
        cl_button.setDown(True)
          
        # creating label
        label = QLabel("GeeksforGeeks", self)
  
        # setting label geometry
        label.setGeometry(50, 100, 200, 40)
  
        # getting down property
        value = cl_button.isDown()
        # setting text to the label
        label.setText("Down : " + str(value))
  
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 :
