Wicket Trees - presentation/diagram
I'm preparing a presentation on Trees in Wicket (core) for the
http://jweekend.com/dev/LWUGReg/ London Wicket Users Group event on
Wednesday.
Could someone (Matej maybe ;-) take a quick look over
http://jweekend.com/presentation/WicketCoreTrees.png this high level UML
class diagram (~1024x768) I have started putting together to explain the
inner-workings/key-concepts to go along with the demo-code/slides on how to
use these components?
Also let me know if you feel this sort of thing is helpful for people
learning Wicket.
Regards - Cemal

Hi,
the DefaultAbstractTree is included only for backwards compatibility
and will be most probably removed in 1.4. I agree that javadoc could
be a bit clearer on this.

Re: Wicket Trees - presentation/diagram
Posted by jweekend <jw...@cabouge.com>.
Thanks Matej. I think it's OK to go in to this level of detail because at the
AbstractTable level there's some nice design/implementation, so, it is
instructive. I will also explain the Swing side (TreeModel etc) in a bit
more detail.
Of course, the code examples and slides will demonstrate how to use these
trees on web-pages, but because of the aforementioned good-design, it is
pretty easy to use these components and won't take very much time. If we do
have time, and the audience is interested, I'll go on to show the guts and
how it all works under the covers. Either way, I personally find this a good
way to understand how things work.
While we're on the subject, what's the deal with the trees in the
extensions? I guess there is going to be some rationalisation of the
DefaultAbstractTree class in 1.4 (?); it's not really obvious whether to
subclass BaseTree (from core) or DefaultAbstractTree (from extensions) for
one's own tree implementation, by just looking quickly at the APIs, code or
the javadoc.

Hi,
the diagram looks ok, however it covers a lot of internal tree state,
which is something the users shouldn't be botherered with. Are you
sure you want to go into such details?
