You should be aware that there is a considerably different API
in the new library: the architecture is completely different
and most notably internals are no longer exposed to public view.
public class ProgressBar
The ProgressBar is typically used to display the progress of a long running operation. It provides a visual clue that processing is underway. The ProgressBar can be used in two different modes: percentage mode and activity mode.
When an application can determine how much work needs to take place (e.g.
read a fixed number of bytes from a file) and can monitor its progress, it
can use the ProgressBar in percentage mode and the user sees a growing bar
indicating the percentage of the work that has been completed. In this mode,
the application is required to call setFraction(double)
periodically
to update the progress bar.
When an application has no accurate way of knowing the amount of work to do,
it can use the ProgressBar in activity mode, which shows activity by a block
moving back and forth within the progress area. In this mode, the application
is required to call pulse()
periodically to update the progress bar.
There is quite a bit of flexibility provided to control the appearance of the ProgressBar. Functions are provided to control the orientation of the bar, optional text can be displayed along with the bar, and the step size used in activity mode can be set.
