[news.eclipse.platform.rcp] Re: Problem using Swing from org.eclipse.cor

[hgm1@xxxxxxxxxxx (Harold Mills)]

Thank you for the suggestion. I have tried using both invokeLater and
invokeAndWait to construct and show my JFrame and it makes no difference.
The call to setVisible still returns immediately.

The only explanation I can think of for this is that my program might have
already created and shown another Swing component. But I believe that the
only other code that should have run by the time my IPlatformRunnable is
called is from the Eclipse runtime, which presumably does nothing with
Swing. So I'm afraid I still don't see what's wrong.
