PyQt5 – 为按钮设置边框

在本文中，我们将了解如何为 Push Button 添加边框。虽然按钮已经有一个边框，但该边框是默认的。 PyQt5 允许我们使用setStyleSheet方法来改变按钮的边框。

下面是带有默认边框和自定义边框的按钮示例。

Syntax : button.setStyleSheet(“border :3px solid green”)

Argument : It takes string as argument

Action performed : It changes the border of the button

代码 ：

# importing libraries
from PyQt5.QtWidgets import * 
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, 600, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
    # method for widgets
    def UiComponents(self):
  
        # creating a push button
        button = QPushButton("CLICK", self)
  
        # setting geometry of button
        button.setGeometry(200, 150, 100, 40)
  
        # adding border to button
        button.setStyleSheet("border :3px solid green")
  
        # adding action to a button
        button.clicked.connect(self.clickme)
  
  
    # action method
    def clickme(self):
  
  
        # printing pressed
        print("pressed")
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
