PyQt5 |如何在进度条中间设置百分比指示器？

在本文中，我们将了解如何在进度条内设置百分比指示器。当我们创建进度条时，百分比指示器默认位于进度条的右侧，即进度条之外。

以下是正常百分比指标的外观与其内部的外观。

In order to do this we will do the following :

1. Create a progress bar.
2. Set its alignment to center

为了改变进度条的对齐方式，我们将使用setAlignment方法。

# importing libraries
from PyQt5.QtWidgets import * 
from PyQt5 import QtCore
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(70)
          
        # changing the alignment of progress bar
        bar.setAlignment(QtCore.Qt.AlignCenter)
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
