Syntax : bar.maximum()

Argument : It takes no argument

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())
