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 ())
