Hey

I have a TitleAreaDialog containing a TableViewer. Not too different from the basic snippet example:
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.jface.s nippets/Eclipse%20JFace%20Snippets/org/eclipse/jface/snippet s/viewers/Snippet001TableViewer.java?view=markup

Now, the contents of the table are something that will take some time to calculate, so I want to do this in a background job in a separate thread and have the table show the contents as they are done.

What is the best way to handle the communication between the background job and the Table?

Take a look at
http://wiki.eclipse.org/JFaceSnippets#Snippet047WizardWithLo ngRunningOperation
which does something similar with a wizard.

Thanks!

I did not get that code example to work ("Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/core/runtime/IStatus"), but it helped me forward. The key seems to be the asyncExec method call.
