PyQt5 – 如何创建圆形标签?

当我们创建标签时,默认情况下它们是矩形的,我们可以使用resize()方法来改变它的宽度和高度,但它仍然是四边形的。

在本文中,我们将看到如何创建圆形即圆形标签。为此,我们将首先创建一个方形标签,然后借助setStyleSheet()方法将其边框半径更改为标签长度的一半,如下所示。

pyqt-圆形标签

代码 :

# importing the required libraries
  
from PyQt5.QtWidgets import * 
from PyQt5.QtGui import * 
from PyQt5 import QtCore
from PyQt5.QtCore import Qt
import sys
  
  
class Window(QMainWindow):
    def __init__(self):
        super().__init__()
  
  
        # set the title
        self.setWindowTitle("round label")
  
        # setting  the geometry of window
        self.setGeometry(60, 60, 600, 400)
  
        # creating a label widget
        # by default label will display at top left corner
        self.label_1 = QLabel('round label', self)
  
        # moving position
        self.label_1.move(100, 100)
  
        # making label square in size
        self.label_1.resize(80, 80)
  
        # setting up border and radius
        self.label_1.setStyleSheet("border: 3px solid blue;
                                    border-radius: 40px;")
  
        # show all the widgets
        self.show()
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 :
pyqt-circle-QLabel
