In this article we will see how to set the maximum value of progress bar. By default the maximum value of progress bar is 100, but we can change it to our need. In order to do this we will use setMaximum
method, this will change the maximum value of progress bar.
Note : When we will set the value to progress bar using setValue
method, the percentage may or may not be equal to the value passed in it, it depends on the range of progress bar.
percentage = ((value_passed - minimum_value)/(maximum_value - minimum_value))*100
Here, minimum_value = 0, value_passed and maximum_value is set by user.
Syntax : bar.setMaximum(maximum_value)
Argument : It takes argument.
Action performed : It will change the maximum value of progress bar.
Below is the implementation.
# 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( 1000 ) # setting value to progress bar bar.setValue( 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 ()) |
