PyQt5 – 标签的双边框

在本文中，我们将看到如何为标签制作双边框。默认情况下，标签本身没有任何边框，尽管我们可以为标签添加边框。下面是单边框与双边框的样子。

为此，我们将使用setStyleSheet方法。

Syntax : label.setStyleSheet(“border : 7px black; border-style : double;”)

Argument : It takes string as argument.

Action performed : It will add double border to the label.

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, 600, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
    # method for widgets
    def UiComponents(self):
  
        # creating a label
        label = QLabel("Geeks", self)
  
        # setting geometry of label
        label.setGeometry(200, 150, 100, 40)
  
        # creating double border to the label
        label.setStyleSheet("border : 7px black; border-style : double;")
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
