A Simple jTextPane Problem

Hi all,

How do I code a jTextPane so that when a user clicks on (let say the
content of the jTextPane is "How are you?") the word "How" (only), that
word will appear in another jTextPane?

Any helps/samples would be greatly appreciated.

Thanks for your time.

Hi MM,

Stop the hate (from your blog) - right on! I put a little quote on my
gmail profile that I you might enjoy. Hope this sample (below) is
useful.

Cheers,

Hi Dan,

Courage Dan..and yes, it's indeed not too late to build a better
world..:)

Thank you for the sample. Appreciate it. But I think I have missed
something in the first post though. You did answer my question anyway.
Here they are:

1. Let say the content of the jTextPane is "Click Me" (like in your
sample). Now when we click at the word Click only (instead of the whole
pane like the sample), the word Click will appear in the other
jTextPane.
-It may have something to do with hyperlink, I guess.

2. The word Click that we click wont disappear, instead both jTextPanes
will have the word Click.

I'm currently modifying the sample you gave, but if you have the idea,
please tell.

Thanks for your time. :)

Have a look at the getCaret(). On a click you will likely want to see
if "dot" changed and is in the middle of a word.
