Tree view of class structure

Can I view my Class structure as a hierarchy in a tree view.

I am prototyping my applications by creating the Class structure first, then adding properties and then concentrating on the methods.

Viewing this as a structure or (better) exporting to something like MindMap or Freeplane (preferred) would be an absolute hoot.

maybe save the project as text format (for version control) and open the files.
with Introspection you could see this class at runtime.
something useful is adding notes to the project, i use it as clipboard or memory.

A while back I made a demo app for drawing trees graphically. You’ll need to adapt it, introspection would be a way to automate this, depending on what you want to do.

The project and a description of the method per below.
