I believe the only static instance of anything is the TreeModelColumnRecord-derived 
      static DLF_ModelColumns DLF_Columns;
This is how the tutorial creates it, because it's needed purely as a reference point for doing stuff. Perhaps the tutorial is misleading, and I ought to create it as a member of the class that uses the TreeView?

Anyway, I discovered I could avoid the problems by declaring my pointer as 
   Gtk::TreeModelColumn<void*>            dataitem;

This does mean that every time I use it I have to explicitly type-cast, which is ugly, but it seems to work.

Thanks,
Rob
