public class ScaleControl

extends javax.swing.JPanel

implements javax.swing.SwingConstants

ScaleControl is a class that displays a GUI component for displaying a value with two sliders and a text field. One slider sets the coarse resolution of the control. The second slider is a continuous control and allows setting of the value. The text field allows the user to set the value directly and read the value as it is being adjusted.
