PyQt5 QCommandLinkButton – 为其设置边框

在这篇文章中，我们将看到如何为QCommandLinkButton设置边框。命令链接按钮是一种特殊的按钮类型，它同时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边框，尽管当它被按下时我们可以看到边框，我们也可以为它设置自定义边框。下面是自定义边框的样子

PyQt5 QCommandLinkButton - 为其设置边框

为了做到这一点，我们将为它设置样式表代码，为此我们使用命令链接按钮对象的setStyleSheet方法，下面是样式表代码

QCommandLinkButton
{
border : 2px solid black;
}

以下是实施情况

# 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 style sheet
        # setting border to it
        cl_button.setStyleSheet("QCommandLinkButton"
                                "{"
                                "border : 2px solid black;"
                                "}")
  
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
