PyQt5 – 如何在进度条中添加边距

在这篇文章中，我们将看到如何为进度条设置边距。为了给进度条添加边距，我们必须修改样式表代码，即进度条的内部部分（加载条）。

下面是样式表的代码。

QProgressBar::chunk 
{
background-color: pink;
margin: 5px;
}

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 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(150, 150, 200, 30)
  
        # set value to progress bar
        bar.setValue(40)
  
        # setting alignment to center
        bar.setAlignment(Qt.AlignCenter)
          
        # setting background color and margin
        bar.setStyleSheet("QProgressBar::chunk "
                          "{"
                          "background-color: pink;"
                          "margin: 5px;"
                          "}")
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
