Basically, what you are looking for is implemented as a progress bar in Windows
- I don't know which platform you are targetting.
Perhaps the Nifty Progress Bar by Don Cole (
http://www.rapideuphoria.com/progress.zip ) is all you need.

If you want still more control over the meter's appearance, the Windows API
allows it through custom draw notifications (look for this on MSDN for details).
I don't know of any Eu library that wraps this functionality at the moment, but
all major GUI libs I know definitely provide the tools to do so.
