PyQt5 – How to set minimum value of progress bar ?

In this article we will see how to set the minimum value of progress bar. By default the minimum value of progress bar is 0, but we can change it to our need. In order to do this we will use setMinimum method, this will change the maximum value of progress bar.

If we change the minimum value, percentage will change accordingly

percentage = ((value_passed - minimum_value)/(maximum_value - minimum_value))*100

Here maximum_value = 100, value_passed and minimum_value is set by user.

Syntax : bar.setMinimum(minimum_value)

Argument : It takes integer as argument.

Action performed : It will set the minimum value of progress bar.

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 minimum value of progress bar to 50
        bar.setMinimum(50)

        # setting value to progress bar
        bar.setValue(90)

        # 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())

Output :
