In this article we will see how exactly we can set and get the description of the progress bar. Sescription of 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 :
setAccessibleDescriptiontakes string as argument.accessibleDescriptiontakes no argument.Return :
setAccessibleDescriptionreturns None.accessibleDescriptionreturns string.
Below is the implementation.
