A simple gauge with a label that is suitable for use in places like a
|
|
status bar. It can be used in either an automatic indeterminant
|
|
(pulse) mode or in determinante mode where the programmer will need to
|
|
update the position of the progress bar. The indicator can be set to
|
|
hide itself when it is not active.
