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 ()) |
