Re: [udig-devel] how to start threads with monitor?

[Andrea Antonello <andrea.antonello@xxxxxxxxx>]

Thanks for your reply Zlatko,
I tried also the Job way, but I get the same Invalid Thread Access
exception:

Job job = new Job("my job ") {
     protected IStatus run(IProgressMonitor monitor) {
           domyCodeWork()
           return Status.OK_STATUS;
        }
     };

  job.schedule();


Also the code you modified below doesn't work with the same error...

I'm really confused (and I'm rather new to RCP and SWT), sinced in my
opinion it happens often that you launch a dialog and while the dialog
is there you do some work, without freezing the interface. But I can't
find working examples.

In swing there was this SwingUtilities.invokelater that worked pretty well.

I guess I 'm missing something of the deeper theory.

Isn't there in udig an Action that does something like that?
