image mapping in java!!

[qb828]

Hi Guys!

I am a little lost and don't know where to start.
My client need a little applet which will map an image.

I know how to map an image in html. But i can't draw a picture of this applet.

Can you help me and kinda tell me what i need to do.

I have a small country map image. How this should work is when i hover around and click over certain region, it should take you to that web site.

It sounds very simple. But I haven't done coding java for a while. I consider myself as little more than beginner.

<img src=&quot;#&quot;myimage.jpg&quot;><map><area shape=&quot;&quot; coords=&quot;> will give me what I need. But i Need to do this in applet.

i also included the image in applet, by getImage(). what it does is it created two images.

Don't I upload the image in java code too or not?

What I want to do is , when i move my mouse over the certain region, i have display certain stats.

can you help me?? thanks.

I guess it is called &quot;hotspot&quot;.
I know that is some certain editors you can use.
I just need to do it with a simple java.

This sounds correct, as you have one image in the HTML, and one in the applet ... remove the one in HTML.

This is a little trickier than just adding an image map in HTML and javascript.

Remember that an applet is a Java program running inside a browser, and really has nothing to do with HTML apart from the <applet> tag used to embed the applet. To achive your desired results you will need to employ AWT and maybe some Swing, using classes like MouseMotionListener to detect when a user has the mouse over a certain part of the applet frame. These events will then need to be captured, and then manipulate the captured MouseEvent to determine your desired action (ie displaying data).
