In this article, we will see how exactly we can set and get the description of the progress bar. The description of the progress bar is basically detailed information of the progress bar like what thing progress bar represent and what formatting and styling we have done, there is no particular format for the description it can be normal casual language.
In order to set the description of progress bar we use setAccessibleDescription method and for getting the description we use accessibleDescription, if no description is set accessibleDescription method will give results as null string.
Syntax :
bar.setAccessibleDescription(info) bar.accessibleDescription()Argument :
setAccessibleDescription takes string as argument.
accessibleDescription takes no argument.
Return :
setAccessibleDescription returns None.
accessibleDescription returns string.
Below is the implementation.
# importing libraries from PyQt5.QtWidgets 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 , 100 , 200 , 30 )
# setting the value
bar.setValue( 70 )
# setting alignment to center
bar.setAlignment(Qt.AlignCenter)
# setting the description
bar.setAccessibleDescription( "Description of progress bar" )
# getting the description
des = bar.accessibleDescription()
# creating label to display description
label = QLabel( "Description = " + des, self )
# adjusting the size of label
label.adjustSize()
# moving the label
label.move( 200 , 150 )
App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
