     extends kh.awt.Dial
{
          // Fields 1

          // Constructors 1
     public AnalogDial();

          // Methods 5
     protected Point getCenter();

This class provides round dials - you probably want HandedDial for most uses.

Summary  |  Top

   public AnalogDial() 

Default constructor

   protected Point getCenter() 

   protected int getMaxRadius() 

   protected Point getPoint(double angle, 
                            int radius) 

   protected void paintComponent(Graphics g) 

Overrides:

paintComponent in class JComponent

   public abstract void setValue(double value) 

This method is needed to support the ValueReceiver interface. A scaled dial only has bounds - it does not yet have a way of actually displaying a result. Subclasses need to implement this method.

Overrides:

setValue in class Dial
