Give notification features to any javax.swing.JFrame or javax.swing.JWindow object.
JCarrierPigeon is a small library written in Java that provides notification features to any javax.swing.JFrame or javax.swing.JWindow object. It currently supports multiple windows to be displayed at once, though it requires some fine tuning on that. In order to achieve a greater effect, it is highly recommended to remove the window border of the provided javax.swing.JFrame. You don't need to worry about removing borders if you are using javax.swing.JWindow, since it has no borders at all.
