PyQt5 – 不同大小的填充进度条

在这篇文章中，我们将看到如何为进度条的不同面设置不同的填充尺寸，下面是正常填充的进度条和不同尺寸的填充进度条的对比。

为了做到这一点，我们必须改变进度条的CSS样式表，下面是样式表的代码。

QProgressBar
{
border : 1px solid black;
padding-top : 10px;
padding-left: 20px;
padding-right:10;
padding-bottom : 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(200, 150, 200, 30)
  
        # set value to progress bar
        bar.setValue(100)
  
        # setting alignment to center
        bar.setAlignment(Qt.AlignCenter)
  
        # setting different padding size
        # and border to progress bar
        bar.setStyleSheet("QProgressBar"
                          "{"
                          "border : 1px solid black;"
                          "padding-top : 10px;"
                          "padding-left: 20px;"
                          "padding-right:10;"
                          "padding-bottom : 5px;"
                          "}")
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 :
