Throw away certain key events for Table? [message #459102]

I am writing my first SWT app, and don't really know how to find the
answer to my question other than to ask you guys.

I have an SWT Table in my application. This table supports keyboard
navigation in the way that I would expect, which is good.

I've added a KeyListener to this table, which I use to enable certain
special keys to perform actions.

What I would like to do is to filter out certain keys from being sent to
the Table's default key handler. For instance, if I press '=', my program
performs the special action for '=' (implemented by my keylistener) but
then jumps to any entry whose text begins with '='. After handling that
keypress, I'd like to throw it out.

I'm used to overriding some handleKey() method and then only calling the
handleKey() for the superclass when I want to pass the event on. Is there
some sort of analogous hierarchy for event handling in SWT?

Thanks a lot,

Well, I figured out one way to do it. If I set the field e.doit to false
in the event, then it is ignored. There must be a better way, though,
because this is kinda nasty... ideas?

Nope. That's the right way to do it.
