Is it possible to use a progress bar in Photoshop?

Hi,

I'm developing an automation plug-in to Photoshop. It take long time to do the
work, I therefore want to start a none modal dialog with a progress bar and a
cancel button. I did not find any example of this in the SDK. Is it possible to
use any of the functions in the PIProgressSuite.h for this kind of dialog?

Regards,

When the the Progress Suite is acquired from an automation plug-in, only a
subset of its routines are available. For instance, TestAbortProc is available,
but UpdateProgress is not. I haven't tried the Progress_* routines, so I don't
know whether they're available or not. The documentation on the topic is scarce,
and there are no relevant examples in the SDK. After searching around for a
while, I decided it would be quicker to implement my own (OS-specific) progress
bar.
