[Advanced-java] Java Swing question.

[nikolaos@xxxxxxxxx (Nikolaos Giannopoulos)]

Are you sure this behaves like this.  What is the code snippet that you are
using and what component are you dealing with e.g. JTextPane, JEditorPane.

I'll guess that its not getCaretPosition() that is your problem but how you
are then using that position to index into your document.  Post the code
(including the portion that inserts it into your document) and possibly I
can help.

Personally I don't think you should have to resort to a buffer or any sort
of token substitution mechanism.

Think about it if you have a document with say just 5 newlines does it make
any sense that you would only be able to insert into it at only the
beginning or the end (assuming as you put it getCaretPosition() ignores
newlines in providing a position)- I don't think so.

Have you tried SUNs notepad example (last time I saw it it was as a JWS demo
app but I'm sure you can find a tutorial on the SUN site - I can't imagine
that it behaves in this way but I guess the proof would be in the pudding).
If not SUNs and you use any commercial IDE they typically come with a
notepad example (at least JB does).  It would take you all of 30 seconds to
prove/disprove your theory (assuming you can get it).
