PyQt5 – maximum() method for Progress Bar
  • Last Updated : 22 Apr, 2020

Progress Bar in PyQt5 allows us to set the range of value for the progress bar. maximum method is used to get the maximum value of progress bar i.e upper limit of the range. This method returns the integer value, if we don’t set the range by default it is 100.

Syntax : bar.maximum()

Argument : It takes no argument

Return : It returns integer.

Code :






# 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 200
        bar.setMaximum(200)
  
        # setting value to progress bar
        bar.setValue(100)
  
        # getting maximum value of progress bar
        value = bar.maximum()
  
        # creating label to print the value
        label = QLabel("maximum value = " + str(value), self)
  
        # adjusting the size of label
        label.adjustSize()
  
        # 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())
