on second thoughts, I'm not sure I follow the design here.
Greg, how is TextAreaContentListener meant to be used?
I would have thought that it would expose events for changes to the
content of a paragraph as well as changes in the Sequence<Paragraph>
collection.
Or am I missing something?

That's a valid bug. Please log a JIRA issue for that.

Hi,
I'm trying to get information about text removed from TextArea
component. In the ParagraphListener, which I used for text changes
tracking, there are two methods:
- void textInserted(Paragraph paragraph, int index, int count) - this
one is perfect for me, I can retrieve inserted text from the
paragraph's CharSequence (using getCharacters() method), I have all I
need: index and count
- void textRemoved(Paragraph paragraph, int index, int count) - here
my problem begins, paragraph received as parameter has no text I'm
looking for because is has been already removed.
Of course I can make a deep copy of paragraph's characters (every
time it changed) and search for my removed text using previously
created copy, but is it really the only way I can do that? It's quite
expensive.
I checked the source and in the TextArea.Paragraph class in the
method void removeText(int index, int count) there is a line where
real text removal operation takes place: characters.delete(index,
index + count), but removed text is not stored or passed to any of
the listeners.
Thanks,
Rafal
