Summary  |  Top

   public Dial() 

Default constructor

   public DoubleRange[] getAdvisoryRanges() 

Returns the range of values which should be colored yellow. or empty for no yellow ranges

   public JComponent getComponent() 

Implements:

getComponent in interface AwtValueReceiver

   public Dimension getPreferredSize() 

Overrides:

getPreferredSize in class JComponent

   public DoubleRange[] getWarningRanges() 

Returns the range of values which should be colored red or empty for no red ranges

   public void setAdvisoryRanges(DoubleRange[] array) 

Sets the range of values which should be colored yellow. or empty for no yellow ranges

   public void setMaxValue(double value) 

   public void setMinValue(double value) 

   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.

   public void setWarningRanges(DoubleRange[] array) 

Sets the range of values which should be colored red or empty for no red ranges
