Even when the tree is built-up lazily?

What we do in the wx GUI is to tell the wx tree that some node has  
children or not based on the list of pointers to children that the node's  
item carries around. Only when the tree item is opened, we start actually  
resolving the pointers (one level deep, there the process repeats).
