PyQt5 – 如何创建标签的虚线边框？

在本文中，我们将了解如何在 PyQt5 应用程序中创建标签的虚线边框。一般来说，当我们创建一个带边框的标签时，边框是连续的，但我们也可以制作一个虚线边框。下面显示了正常和虚线边框的不同之处。

为了做到这一点，我们将使用setStyleSheet()方法。

Syntax : label.setStyleSheet(“border :3px black; border-style : dashed”)

Argument : It takes string as argument

Action performed : It makes the border dashed.

代码 ：

# importing the required libraries
  
from PyQt5.QtCore import * 
from PyQt5.QtGui import * 
from PyQt5.QtWidgets import * 
import sys
  
  
class Window(QMainWindow):
    def __init__(self):
        super().__init__()
  
  
        # set the title
        self.setWindowTitle("Python")
  
        # setting  the geometry of window
        self.setGeometry(60, 60, 600, 400)
  
  
        # creating a label widget
        self.label_1 = QLabel("Normal border", self)
  
        # moving position
        self.label_1.move(100, 100)
  
        # setting up the border and padding
        self.label_1.setStyleSheet("border :3px solid black;")
  
        # resizing label
        self.label_1.resize(100, 80)
  
        # creating a label widget
        self.label_2 = QLabel("Dashed border", self)
  
        # setting up the dashed border
        self.label_2.setStyleSheet("border :3px solid black;
                                    border-style : dashed")
  
        # moving position
        self.label_2.move(230, 200)
  
        # resizing the label
        self.label_2.resize(100, 80)
  
        # 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())
