[Fxruby-users] Thoughts on the tree list

[Hal F. <ha...@hy...>]

OK, I'm making slow and painful progress on this app of mine
(http://tycho.rubyforge.org).

Eventually I want to fix the tree list so that the items can
be re-ordered manually.

This is daunting to me. A few months ago I read about the
cut-and-paste API, which I thought would be trivially simple
and is not at all. I also read about drag-and-drop, which is
somewhat related, and it is even more painful.

The tree list itself is thorny to understand, and drag/drop
is even worse. Doing drag/drop inside a tree list sounds as
exciting as a trip to the dentist in a third world country.

Wouldn't it be nice if someone wrote a widget (probably
inheriting from the tree list) which could be rearranged in
such ways, and was smart enough to "reflect" itself in a
tree datastructure? Then we could plug in such a widget without
worrying about writing that extra 200 lines of code, no?

But I'm just dreaming there. There's probably some reason it's
not doable that way.

Anyhow, if anyone has any words of wisdom in this area, I'll be
glad to listen...


Cheers,
Hal
