Creating a progress bar for loading MP3 files with
ActionScript
The following example loads several songs into a SWF file. A progress bar, created using the
Drawing API, shows the loading progress. When the music starts and completes loading,
information appears in the Output panel. For information on loading MP3 files, see “Loading
an MP3 file” on page 599.
NOTE
If you test this code a second time, the image will be cached and the progress bar will
complete right away. To test multiple times, use different images and load them from
an external source. A local source might cause problems with testing your
application because the content loads too quickly.
