CClassView : public CMFCToolBar, the propetary of the CTreeCtrl object, is a
member of the

class CMainFrame : public CFrameWndEx

To show in the CTreeCtrl the document data, CClassView must have a reference
of the CDocument object or is there a better way?

Ravnock:

You should not refer to an object that is not derived from CView as a view, nor
give it a name like CClassView.

One (not very good OOP way) would be to do, in your 3D render view:

CMainFrame* pMainFrame = (CMainFrame*)AfxGetMainWnd();

Now you can call any method on the main window, and have the main window update
the tree view (which is the grand-child of the main window, if I am
understanding you).

A slightly better way (does not require casting) is to send a custom message to
the main window, to accomplish the same purpose. CWnd::SendMessage() acts like a
"universal virtual function" for any CWnd-derived class.
