Detailed Description

wxDataViewTreeStore is a specialised wxDataViewModel for storing simple trees very much like wxTreeCtrl does and it offers a similar API.

This class actually stores the entire tree and the values (therefore its name) and implements all virtual methods from the base class so it can be used directly without having to derive any class from it, but it is mostly used from within wxDataViewTreeCtrl.
