PyQt5 QCommandLinkButton – 获取图标

在本文中，我们将了解如何获取 QCommandLinkButton 的图标。默认情况下，箭头被设置为命令链接按钮的图标，尽管我们可以随时在setIcon方法的帮助下更改它。

为了做到这一点，我们使用带有命令链接按钮对象的icon方法

Syntax : button.icon()

Argument : It takes no argument

Return : It return QIcon object

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, 150, 50)
  
        # making it checkable
        cl_button.setCheckable(True)
  
        # icon
        icon = QIcon('logo.png')
  
        # changing icon
        cl_button.setIcon(icon)
  
        # creating label
        label = QLabel("GeeksforGeeks", self)
  
        # setting label geometry
        label.setGeometry(50, 100, 200, 40)
  
        # making label multiline
        label.setWordWrap(True)
  
        # getting icon of the button
        value = cl_button.icon()
  
        # setting text to the label
        label.setText("Icon " + 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 ：
