Hi all,

How do I code

<software> Instructions for a computer in some programming
	language, often {machine language}.  The word "code" is often
	used to distinguish instructions from {data} (e.g. "The code
	is marked 'read-only'") whereas "{software}" is used in
	contrast with "{hardware}" and may consist of more than just
	code.

	(2000-04-08)

a jTextPane so that when a user click

<hardware> To press and release a {button} on a {mouse} or
	other {pointing device}.  This generates an {event}, also
	specifying the screen position, which is processed by the
	{window manager} or {application program}.  On a mouse with
	more than one button, the unqualified term usually implies
	pressing the left-most button (with the right index finger),
	other buttons would be qualified, e.g. "{right-click}".
	{Keyboard} modifiers may also be used, e.g. "shift-click",
	meaning to hold down the shift key on the keyboard while
	clicking the mouse button.

	If the mouse moves while the button is pressed then this is a
	{drag}.

	(1995-03-14)

s 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/sample

<digital signal processing> The result of measuring the
	amplitude of an analog signal at a specified time.  In
	{digital signal processing} a sample is a signed or unsigned
	number and the number of samples per second is called the
	{sample rate}.

s'd 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

<language> A {functional programming} language designed by
	R.M. Burstall, D.B. MacQueen and D.T. Sanella at {University
	of Edinburgh} in 1978.  It is a large language supporting
	user-defined {prefix}, {infix} or {distfix} operators.  Hope
	has {polymorphic} typing and allows {overloading} of operators
	which requires explicit type declarations.  Hope has {lazy
	lists} and was the first language to use {call-by-pattern}.

	It has been ported to {Unix}, {Macintosh}, and {IBM PC}.

	See also {Hope+}, {Hope+C}, {Massey Hope}, {Concurrent Massey
	Hope}.

	{(ftp://brolga.cc.uq.oz.au/pub/hope)}.

	[R.M.Burstall, D.B.MacQueen, D.T.Sanella, "HOPE: An
	experimental applicative language", Proc. 1980 Lisp conf.,
	Stanford, CA, p.136-143, Aug 1980].

	["A HOPE Tutorial", R. Bailey, BYTE Aug 1985, pp.235-258].

	["Functional Programming with Hope", R. Bailey, Ellis Horwood
	1990].

this sample (below) is
useful.

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've 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've the idea,
please tell.

Thanks for your time. :)

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