- Jun 23, 2006You could just iterate through thr Nodes changing the label text to the
correct value to change the appearance to being sorted.
It should be possible to write a node sorting method. Just look at
treeview.js. Each Node has an array called "children", each of which is
Every child Node has a nextSibling and previousSibling pointer. You can
sort that array as you see fit, then make a pass through updating the
sibling pointers, call refresh() on the parent Node, and that *should*
do it... YMMV!
I've done a bit of "Node shuffling" when adding drag and drop to my
DDTreeView class, so I think that should work.
