How to create an image map using Java Swing?

Question

I need to make an image map using Swing that displays a background image, and then when the mouse hovers over (or clicks) specific hotspots, I need to pop up a \'zoomed-in\' ima

Answer 1

To listen to the mouse clicks implement the MouseListener interface, and add it to your panel. Then when the click is recieved you can use a JPopupMenu as you suggested, or you could even use a glass pane to show the zoomed in image.

I'm guessing you want to achieve something similar to this post by Joshua Marinacci, he has also posted the source here, I would take a look at that.

Answer 2

I would probably:

• create some instance of Shape that represents each of your hotspots (could be a plain boring old Rectangle, or see GeneralPath if you need to create fancy shapes)
• register a MouseListener which iterates through each of the Shapes and calls its contains() method to see if the clicked coordinate is inside the hotspot in question
