SOLVED Using maxon::BaseList with a TreeView?

Is this possible or should I simply maintain my own class double-links?

Hi @Kuroyume0161, first of all, welcome back in the plugincafe community, I'm glad to see you here!

Unfortunately, this is not possible to use directly a BaseList with a TreeView and as you already figured it out, you have to maintain this list yourself.

While it's very nice that a TreeView offer this abstraction level, and allows to make a list from any kind of data, it has the overhead to builds this TreeView layer.
