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 :
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__()
self .setWindowTitle( "Python " )
self .setGeometry( 100 , 100 , 600 , 400 )
self .UiComponents()
self .show()
def UiComponents( self ):
bar = QProgressBar( self )
bar.setGeometry( 200 , 150 , 200 , 30 )
bar.setMinimum( 50 )
bar.setValue( 90 )
bar.setAlignment(Qt.AlignCenter)
App = QApplication(sys.argv)
window = Window()
sys.exit(App. exec ())
