How do I get a menu item to refresh? [message #777183]

I have an ArmListener on a menu item so I can update the menu item text (or it's enabled state) when it's about to be shown.
The problem is that it displays with it's "old" text/state - until the mouse rolls over it. THEN it updates to the state/text I set.

So, how do I get it to immediately update?

SWT.Arm is fired on the menu item when the mouse rolls over it. Sounds like that it what it is doing, just not what you want?

The containing Menu will get an SWT.Show even just before it opens, and that's what code like the MenuManager uses to update its contained MenuItems just before a menu appears. Is that what you want?

Very likely! Thanks.
None of the examples I found showed that, and the javadocs tend to be rather terse.

For a similar example see
