PyQt5 – 在进度条上添加点状边框

在这篇文章中，我们将看到如何在进度条的条上添加点状边框。下面是进度条的正常边框与进度条的点状边框的对比。
PyQt5 - 在进度条上添加点状边框

为了做到这一点，我们必须改变CSS样式表中的边框样式，下面是样式表的代码。

QProgressBar
{
border : 1px solid black;
}
QProgressBar
{
border : 3px red;
border-style : dotted;
}

以下是实施情况。

# 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())
