com.intellij.progress [ #977 ]

I've just found this package; is there any example somewhere? I've tried to figure out the meaning of the different parameters (boolean, Runnable, ...) without any success.

Could you please elaborate a bit on :

com.intellij.progress.util.ProgressUtil() two runnable parameters

as well as :

com.intellij.progress.util.ProgressWindow() boolean parameters.


An example showing how the progress window of the "build project" action is implemented would be great :)

Thanks,
