Hi,
I added the possibility to specify the children of a tree also based on the level at which the item resides.
An example can be found here: GLMBasicExamples>>treeWithChildrenByLevel
Stef, this solves a problem of easily showing both categories and selectors (both being represented by symbols) in the same tree :).
Cheers, Doru

Very cool indeed, I can use that.
What do I do if I have different kinds of objects per level?

You have to take care of that somehow in the children block. The level option is one possibility to distinguish between objects. Another one is a "isKindOf:", but that you can do yourself. It would be interesting to offer other means of mapping (maybe something that builds a map behind the scene), but I would not know how to do that. If you have ideas, I would be happy to hear them :).
Cheers, Doru

Aha, ok. I was quickly looking at the code but couldn't figure out how the specification of the different selectors at different levels worked :-)
It would be interesting to offer other means of mapping (maybe something that builds a map behind the scene), but I would not know how to do that. If you have ideas, I would be happy to hear them :).
I was thinking/expecting more something along a meta-model for trees.
For now I guess the current implementation is fine, I just need to implement some unique selector in all the objects that will be part of the tree that returns their children.

Yes, when you have distinct types you can just either dispatch to them, or use an isKindOf: as a shortcut. The problem comes when you do not have distinct types (for various strange reasons) but you still want to treat the objects differently.
What do you mean by a meta-model for trees? This is what the children: block does. What else would you like?
