Combo processing [message #448452]

I'm hoping for a consistent manner in which to process a Combo widget's info
without processing it too often. Initially I'd had only a selection
listener but this wouldn't get triggered if the person simply tabbed through
the control. So, I added a focus listener triggering on focusLost but I
think this will be triggered any time the dialog box loses focus (e.g., not
just the Combo field) by another application becoming active. Is there a
trick like toggling a boolean with focusGained/Lost that can be checked so
if focusLost is called multiple times in succession I wouldn't process the
listener code?

Best Regards, Nat

The normal thing that people do is do processing on SWT.Selection for
SWT.READ_ONLY combo boxes and SWT.DefaultSelection otherwise. This means
that when a combo box is editable, you need to press return in order to run
an action.
