public class LED

extends javax.swing.JComponent

Multi-color LED-like widget which knows about blinking and autorepainting. LED is a round lamp of a certain color. Color can be changed. Knows furthermore about turning on and off itself, where being off results in drawing in a darker shade of the given color. Can automatically and internally perform blinking, i.e. switching from off to on and vice versa periodically. For convenience reasons, can be set into auto-repaint modus which will repaint the LED if color or on/off is changed automatically. If performance is important (e.g. a field of LEDs to be drawn), this should be turned off. Note however that blinking will always repaint automatically. You should not use internal blinking if you have a larger number of LED elements which should blink. "LED" is the abbrevation of "light emitting diode", an electronic device which emits light of a certain color.
