PyQt5 QCommandLinkButton – 为其设置背景颜色

在本文中，我们将了解如何为 QCommandLinkButton 设置背景颜色。命令链接按钮是一种特殊类型的按钮，它具有按钮和单选按钮的特性。默认情况下，命令链接按钮没有额外的背景颜色，尽管我们可以为其设置自定义背景颜色。下面是自定义背景颜色的样子

为此，我们将为它设置样式表代码，因为我们使用setStyleSheet方法和命令链接按钮对象，下面是样式表代码

QCommandLinkButton
{
background-color : lightgreen;
}

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)
  
        # making it chekable
        # cl_button.setCheckable(True)
  
        # setting geometry
        cl_button.setGeometry(150, 100, 200, 50)
  
        # setting style sheet
        # setting background color
        cl_button.setStyleSheet("QCommandLinkButton"
                                "{"
                                "border : 1px solid black;"
                                "background-color : lightgreen;"
                                "}")
  
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
