PyQt5 – 如何获得进度条的百分比？

在本文中，我们将看到如何获取进度条的百分比值，我们可以使用setValue方法设置进度条的百分比。为了获得百分比值，我们使用text方法返回表示百分比的整数。

Syntax : bar.text()

Argument : It takes no argument.

Return : It return integer.

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 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)
  
        # getting percentage value
        p_value = bar.text()
  
        # creating label to print percentage
        label = QLabel("percentage = " + str(p_value), self)
  
        # moving the label
        label.move(200, 200)
  
        # setting alignment to centre
        bar.setAlignment(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 ：
