Re: [eclipse-incubator-e4-dev] Modelled UI change notification - live mo

[Eric Moffatt <emoffatt@xxxxxxxxxx>]

Tom, in one word "sweet!!' I'd
been working on wiring up the listeners but I'm just not a databinding
guru. I've just taken a look at how you are wiring up the controls/model
and love it...this is a pattern we can make great use of. 

I'm switching over to using it but I
can'tfind SWT text observables for 'Items' (i.e. MenuItem, ToolbarItem,
CTabItem). I'll make a quick patch that adds them (a quick look a 'observeText'
shows that this is fairly trivial).

Nice one,
Eric

I'd certainly like to see this. In particular, when we have talked publically
about how e4 would be more dynamic/responsive to develop for, this was
the kind of thing we had in mind.

I'd argue that it's worth thinking about it soon, since there are potentially
interesting issues w.r.t. state management, SWT widget lifecycle, etc.

... and if we end up with a "destroy and recreate" model, we
need to do a better job of maintaining state than we currently do (e.g.
it's not ok for the tree to be recreated with all the nodes collapsed,
etc.)
