Creating a "ProgressMonitor mirror" of the status view [message #334943]

Hi,

we have a normal Job that does some refreshing ( longer running
calculation recreating a model from input file). That one basically works
fine shows progress in the common places ( bottom right/ Status view /
workbench job dialog). The problem we have now is that in some places we
need to check if the Job is running and if so wait for it to complete.
Ideally while waiting for the job to complete the user should see exactly
the kind of progressbar the statusview is showing. Or at least something
similar. After having finished reading this link
http://book.javanb.com/eclipse-rich-client-platform-designin g-coding-and-packaging-java-applications-oct-2005/ch17lev1se c8.html
it seems o me that the only way to solve that would be to implement a
Progressprovider ourself which unfortunately would kill the workbench's
current Progressprovider ( so the status view)? Can someone verify this
and maybe give some thought input on how to solve the problem. We
definetly do not want to loose the normal workbench handling for the Jobs.

Thanks
Philipp

Hi,

I think you may be able to use JobManager.join if you give your Job a
specific JobFamily. JobManager.join should show the fact that there is a
job waiting as a separate progress bar in the same places as usual.

hth,

The JobManager might be one possible way to accomplish this. However
the JobManager is typically used to manage/monitor all jobs in the
system or a job family.

As you are only concerned with one particular job, you might try
installing a JobChangeListener using the addJobChangeListener() method.
There is also a getState() method which you can use to query the state
of the job.

Here are some more links that might be useful:
http://help.eclipse.org/help32/index.jsp?topic=/org.eclipse. platform.doc.isv/guide/runtime_jobs.htm
http://www.eclipse.org/articles/Article-Concurrency/jobs-api .html

Good Luck
Jay

But would that give you access to the progress bar to indicate you are
blocking?
