Many thanks for your reply. This makes sense, although
it does make it rather more complicated for
subclassers. :) It would be nice if there was a
documented method that did this stripping (eg.
-pastableAttributedString or some such) that
subclasses could use to stay consistent with current
and future releases...
Could you possibly give me a clue on where I would
start to emulate the default behaviour in my subclass?
As I understand it, I will have to check for the
paragraph style attribute across the range and then
look for text blocks within the paragraph style (using
-textBlocks?), although I am still unsure from the
docs about how I check whether the text block is a
table and whether it is represents a different table
across the range...
Thanks again,
Keith
