PyQt5 – Progress Bar description
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.
Python3
# 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 , 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 ()) |
