PyQt5 – 如何获取进度条的值?

在本文中,我们将看到如何获取进度条的值。进程栏的值基本上是用来设置进程栏的百分比。

注意:进度条的百分比和值是不同的东西,它们可以具有相同的值,但百分比取决于进度条的范围和进度条的值,如果进度条的范围是从 0 到 100,那么百分比值将等于值的进度条。

为了获得进程栏的值,我们将使用value方法。

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)
  
        # setting maximum value of progress bar to 1000
        bar.setMaximum(200)
  
        # setting value to progress bar
        bar.setValue(100)
  
        # getting value of progress bar
        value = bar.value()
  
        # creating label to print the value
        label = QLabel("value = " + str(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 :
