The progress bars are for situations where the percentage completed can be
|
||
|
|
determined. They give users a quick sense of how much longer an operation
|
||
|
|
will take.
|
||
|
|
|
||
|
|
There is also a secondary progress which is useful for displaying intermediate
|
||
|
|
progress, such as the buffer level during a streaming playback progress bar.
