How to do animation with JTextArea?

[juliekcf]

Animation is usually done using images. If what I want to move is
actually a JTextArea, how can I move it? There are no initial x- and
y-coordinates for the JTextArea. In my case, there are more than 10
JTextArea in the screen displayed using BoxLayout.

Can anyone help me, please?

Thanks in advance.

You can not do this if you keep the layout manager, it would be fighting it.
If you must set a null layout - Container.setLayout(null); then you have x &
y positioning through Component.setLocation().
Sounds like a bad idea to me though.

Not necessarily, depends on the layout manager.

It is. Even for this situation, it is best to create
a custom layout that suits your needs.

I developed a 'ScrollLayout' for my PhySci
project*. The layout can be seen in action
if you install my PhySci app and open one
of the six progs.
The messages scroll across the top.

You can download the jar itself (contains full source)
at http://www.physci.org/PhySci.jar

* Important note - this was _after_ I had tried
exactly what you suggested, setting the layout
to null and using setLocation (..so I am guilty myself)
