You are correct on both counts. In fact a detailed discussion is
currently taking place on the developers list with regards to the
TInterfaceBase object and how we plan on continuing with the actual
interface between the LCL and the widget set code.

<snip TInterfaceBase and interfaces.pp stuff>

We have been in a slow transition with regards to how the interface is
designed. One is the older method of the connection and one is the newer
method. Some components and features use the old method and some use the
new. Again that is part of the developers discussion right not. We
realize this needs to be cleaned up and we are talking about how we go
about doing it. Both for the purpose of making the code more
understandable but also making it easier for other interfaces to be
written such as the Win32 that is being worked on.

No. It is actually TdggDataSet.

You are correct on this one. It was a typo. (fixed)

Actually there already exists the beginnings of a class diagram. It
currently shows the FCL and stops at the TControl section. MVC did all
of the FCL stuff and I need to add the LCL stuff. Of course I haven't
gotten around to it yet.   :-\

Here is the URL to this diagram.

This is a DHTML file so it might not work correctly in some browsers if
you do have problem you can also get a PDF version of this chart here.

I'm not sure when MVC updated this chart last so it might needs some
additions from him as well.
