PyQt5 - 进度条的虚线边框

在本文中，我们将看到如何为进度条添加虚线边框。下面是进度条的正常边框与虚线边框的表示。

为此，我们必须更改 CSS 样式表中的边框样式，下面是样式表代码。

QProgressBar
{
border : 1px solid black;
}
QProgressBar
{
border : 3px red;
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 border to progress bar
        # and setting dotted border to the bar and color
        bar.setStyleSheet("QProgressBar "
                          "{"
                          "border : 1px solid black;"
                          "}"
                          "QProgressBar::chunk"
                          "{"
                          "background-color : yellow;"
                          "border :3px red;"
                          "border-style : dotted"
                          "}"
                          )
  
  
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
