TextArea and images

Hi,

I am working on a chat applet, and I would like it to show an image
next to some text received from the server. I have looked everywhere I
can think of for a similar piece of code, but I haven't succeeded yet.

I use a TextArea for inserting the text received but I don't know how
to insert the image into the TextArea next to the text. Is there any
way to do this?
I also want some of the text and the image to be hyperlinked to other
web pages for loading upon cliking. I think I have found how to do
this, although I haven't tried it yet.

Any help specially with the first question will be appreciated.

Thank you
Miguel

AWT applets can show images, but..

java.awt.TextArea will not display images.

Yes, you could put the image on a
Canvas/Panel/Component beside the
TextArea, and render the image on it.

You could (theoretically) also use javax.swing.JEditorPane
<http://www.physci.org/api.jsp?license=OK&class=javax.swing.JEditorPane>
to display (simple) HTML formatted text,
with the chat text and image interwoven
in the HTML.

Have you used Swing yet?

JTextPanes support embedded components:

Well that isn't entirely true. You can override paintComponent and display
whatever you like. But that would be an extremely odd thing to do.

First of all, let me thank you for your replies, and apologise for
posting this twice.

My problem is that I am going to use the program in schools and it is
a very heterogeneous environment. I don't know what software nor
hardware it will be used from. So to play it safe I think AWT will be
better (correct me if I am wrong).

Anyway I will try the canvas solution and see how I go. If you have
any further comments I will appreciate them.

Miguel

True. I have to consider whether to type the entire
truth or keep it short and to the point. On c.l.j.help
I often give the abbreviated response in the expectatation
that the OP will find out at a later (relevent) stage
that my statement was not entirely correct.

OTOH, ..if you were going to do your own rendering,
is there any point in sub-classing a more complex
Object than Component? ;-)
