object mapping support with Delphi OVC table

Having just had a look at their documentation, I suspect you may struggle.

Looks like they are DB driven by an underlying data object of some description. I use similar Delphi grids (Tww ones though) and they are pretty complex to interact with because of the separation of visible GUI and underlying data object. Without debug information on, I can't do anything much useful with them.

So they seem very similar (in some ways at least) to the TwwDBGrid I use. But would associating your class with that work? I doubt it unfortunately.
