public class FrameBlinker

extends javax.swing.Timer

implements java.awt.event.ActionListener

A special-purpose Timer which can be used to make a Frame blink on and off at a regular interval. A distinct FrameBlinker is needed for every Frame you wish to blink. A number of experiments indicated that the original version of this class, which called the Frame's hide() and show() methods, interacted poorly with the enclosing window-managing environment. For instance, CTWM flashed the window, but first moved it to virtual screen 1, and minimized it. After some thought, I decided that blinking the title was the best option.
