Java xeyes - Follow the mouse cursor location outside a JFrame

A Java xeyes solution - I started working on my Java speech recognition app again today, and in the process I saw some source code I thought I should post here. When I was developing this app, I thought it would fun to put a GUI on it, and when I thought about what sort of GUI it should have, I thought of the old X-Windows xeyes app. I looked around to see if anyone had written a "Java xeyes" application, but from what I've seen, nobody has.

Java - Getting the mouse cursor location (current mouse position)

Java mouse cursor location FAQ: How do I get the location of the mouse (mouse cursor) in Java?

A custom Java mouse cursor that displays the mouse XY coordinates

Java/Swing FAQ: How do I center a JDialog?

Answer: The answer here really depends on what you mean by "center". If you really want to center a JDialog on screen, you can use code like this:

// center a jdialog on screen

By calling setLocationRelativeTo with null, the JDialog will be centered.

How to center a JFrame on screen

I always center my initial JFrame on screen using the setLocationRelativeTo method, and pass it a null reference. As the Javadoc for setLocationRelativeTo method states:

How to move iPhone application (app) icons around

iPhone apps FAQ: How do I move iPhone apps or app icons? (Related: How do I move iPod or iPad app icons?)

I'm a relatively new owner of an Apple iPhone 3G, and last night, quite by accident, I learned how to move iPhone apps (applications) from one place to another on the iPhone screen. The technique to move an iPhone app is a bit of fun; here's how you do it.
