Zoom on graphic

I'm working on a project right now where I have to draw the Mandelbrot Set in a graphics window. The final part of the project is to "zoom in" on part of the picture and rescale the window to plot that part. I've been messing around with MouseListener, but either my math is wrong or something I'm not even sure about. Any examples would be really helpful as well.

Your best bet is to search the forum and to use Google. Best of luck, and have fun with your Mandelbrot. They can be quite beautiful if done well.
