[platform-ui-dev] busyCursorWhile/ProgressMonitorDialog - what are they

[Pat McCarthy <patmc@xxxxxxxxxx>]

I've tried out the IProgressService
support for running a runnable (PlatformUI.getWorkbench().getProgressService().busyCursorWhile(irun);).

What I'm unsure of is the purpose of
the dialog that opens after a delay.  What is it meant to do for the
user (ProgressMonitorDialog).
 

When it opens it shows me a bit of info
about the active task/progress based on the monitor.  Noticed that
the cursor is busy unless over the Cancel button, but if the Running Jobs>>
button is selected the cursor looses its busy state.  

The jobs bit is the real question.  
There is no relationship between the jobs listed and the runnable task,
at least I have not found a way to create one.  

Why show the jobs?  The can't be
canceled from the dialog. The are not listed because of any dependency
or blocking that might be occurring between the job and runnable task.
  Just seems like a window on information that has no context or usefulness.
 I know the API is marked experimental, but is it intended to have
a targeted use?  If so - can you describe it?
