PyQt5 - 带虚线边框的进度条

在本文中，我们将了解如何为进度条创建虚线边框。默认情况下，进度条的边框是连续的。下面是普通边框进度条与虚线边框进度条的表示。

为此，我们必须更改 CSS 样式表，下面是可与setStyleSheet方法一起使用的样式表代码。

QProgressBar
{
border : 3px black;
border-style : dotted;
}

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 background color to window
        # self.setStyleSheet("background-color : yellow")
  
        # 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 progress bar
        bar = QProgressBar(self)
  
        # setting geometry to progress bar
        bar.setGeometry(200, 100, 200, 30)
  
        # setting the value
        value = 70
        bar.setValue(value)
  
        # setting alignment to center
        bar.setAlignment(Qt.AlignCenter)
  
        # setting dotted border
        bar.setStyleSheet("QProgressBar "
                          "{"
                          "border : 3px black;"
                          "border-style :dotted"
                          "}"
                          )
  
  
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
