Topic: how to count child nodes and how to validate on rename() ?

Hi,

  • Is there a way to count child nodes of any given parent?

  • How can I validate the node's new name on rename()? I think I can just call rename() and restore the previous name if the validation fails, but perhaps there's already a built-in functionality for this?

Regards,

Not again. I'm answering my own question. node.recursive() works for counting the child nodes.  lol lol lol

Hi,

In case someone needs to validate on rename, just do something like:

tree.addEvent('rename', function (node, name_new, name_old) {
    // do validation here
});

where tree is an instance of Mif.Tree
