All Implemented Interfaces:

java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.accessibility.Accessible, ProgressBar

public class ProgressSlider
extends java.awt.Canvas
implements ProgressBar

ProgressSlider for StandardControlPanel.

A simple slider, mostly stolen from JSlider code. This is a bare bones implementation. JSlider can't be used as is. It will make media choppy dealing with all the timer update events generated by control panel.
