Yes, I tried that, but the problem was that a lot of the functionality
has to go to the beginning of the ::editXY ::edit ::metrics functions
that are all inherited from Inset (?). Besides, the code in InsetPreview
had to call other Inset members which wasn't possible anymore.
Anyway..
Why not making a real Inset InsetPreview (:public InsetText) that
previews what is inside. This can then be a mixture of ERTs, normal text
and maybe graphics..
In that way, you can use it for psfrag and stuff like that:
\begin InsetPreview
\begin ERT
\psfrag{a}{b}
\end ERT
\begin InsetGraphics
\file a.eps
\end InsetGraphics
\end InsetPreview
Switching between a previewed ERT and normal ERT is then moving it in or
out of the InsetPreview.
