[Fxruby-users] tree list navigation

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

I'm thinking of using a couple of function keys to move items
up/down in a tree list.

This seems an order of magnitude easier to me than drag/drop.
Am I wrong? Easier to code, not to use, I mean.

So anyway:

It would be nice if there were some concept of "next" and
"previous" that was independent of the actual tree structure,
but dependent on the current collapsed/expanded state of the
tree.

For example: Suppose I have a new entry NEW, and I have F8
mapped to a "move down" command.

Here I'm representing collapsed and expanded nodes by + and -
respectively. Use a monospaced font to look at this. :)

Given this tree:

    - NEW
    + Stooges
    + Dwarves
    + Fates
    + Muses

Suppose I select NEW and press F8 three times -- I'd expect
this as a result:

    + Stooges
    + Dwarves
    + Fates
    - NEW
    + Muses

On the other hand, suppose I start with this tree:

    - NEW
    - Stooges
      - Larry
      - Curly
      - Moe
    + Dwarves
    + Fates
    + Muses

and again select NEW and press F8 three times. I'd then expect:

    - Stooges
      - Larry
      - Curly
      - NEW
      - Moe
    + Dwarves
    + Fates
    + Muses

In other words, traverse the tree "as is" -- is this doable??

Obviously I'd like to be able to move not just single items but
entire subtrees.

Thanks for any insight...
