Hmm, I had never heard of this class before. Had to look it up when I saw
this post. You should be able to use this class. If GEF is consuming the
keystrokes, you might want to take a look at what's going on. Set a
breakpoint in DomainEventDispatcher.dispatchKeyPressed(). However, you
should realize that ActionDelegates are only updated when selection changes,
and so you won't be able to update them at other incidents (such as command
stack change).
I guess the general rule is that stick with the tried and true methods
whenever you can. BTW, you can use key bindings to register actions (or
commands, it seems). That's how GEF registers Ctrl + =/- with the zoom
actions. Look at GEF plugin's plugin.xml.
