By the way, despite the occasional inquiry here, I've never seen an explanation
of the point of all this floating TEView business in the first place (as
opposed to having TEditText simply be a subclass of TTEView). The memory
savings per instantiation are small, but the increased code complexity is VERY
high.

Is an answer from a MacApp support engineer OK? Based on my recollection
talking with the originators of the floating view, there were talks about
deleting the floating TEView construct from MacApp 3.0, but due to time
limits the operation was never done. I agree, the complexity behind 
the floating view is a support/port/maintenance nightmare, a good example
when a splendid idea does not automatically imply a splendid end result.

Cheers,
Kent

Pre-3.0, TEditText could only be used with TDialogView, which was essentially
an objectized version of the toolbox Dialog Manager. So the short answer to
your question is "because that's how the dialog manager did it." As to why
the *dialog manager* used a floating TextEdit record, I suspect the 64k RAM
of the original Macintosh had everything to do with it.
