## contrib.ch.randelshofer.quaqua.colorchooser
Class ColorSliderModel

    java.lang.Object
      contrib.ch.randelshofer.quaqua.colorchooser.ColorSliderModel

Direct Known Subclasses:
  GrayColorSliderModel, HSBColorSliderModel, ICC_CMYKColorSliderModel, NominalCMYKColorSliderModel, RGBColorSliderModel

    public abstract class ColorSliderModel

extends java.lang.Object

Abstract super class for ColorModels which can be used in conjunction with ColorSliderUI user interface delegates.

Colors are represented as arrays of color components represented as BoundedRangeModel's. Each BoundedRangeModel can be visualized using a JSlider having a ColorSliderUI.

Field Summary
`protected javax.swing.DefaultBoundedRangeModel[]` | `components` Components of the color model.
`protected int[]` | `values` Speed optimization.

Constructor Summary
`protected` | `ColorSliderModel(javax.swing.DefaultBoundedRangeModel[] components)` Creates a new ColorSliderModel with an array of BoundedRangeModel's for the color components.

Method Summary

`int` | `getComponentCount()` Returns the number of components of this color component model.
`int` | `getInterpolatedRGB(int component, float ratio)` Returns an interpolated RGB value by using the values of the color components of this ColorSliderModel except for the component specified as an argument.
`abstract int` | `getRGB()`
`int` | `getValue(int component)` Returns the value of the specified color component.
`void` | `removeChangeListener(javax.swing.event.ChangeListener l)`

Field Detail

### components

    protected javax.swing.DefaultBoundedRangeModel[] components

  Components of the color model.

### values

    protected int[] values

  Speed optimization. This way, we do not need to create a new array for each invocation of method getInterpolatedRGB(). Note: This variable must not use in reentrant methods.

Constructor Detail

### ColorSliderModel

    protected ColorSliderModel(javax.swing.DefaultBoundedRangeModel[] components)

  Creates a new ColorSliderModel with an array of BoundedRangeModel's for the color components.

Method Detail

### configureColorSlider

    public void configureColorSlider(int component,
                                     javax.swing.JSlider slider)

  Configures a JSlider for this ColorSliderModel. If the JSlider is already configured for another ColorSliderModel, it is unconfigured first.

### unconfigureColorSlider

    public void unconfigureColorSlider(javax.swing.JSlider slider)

  Unconfigures a JSlider from this ColorSliderModel.

### getComponentCount

    public int getComponentCount()

  Returns the number of components of this color component model.

### getBoundedRangeModel

    public javax.swing.DefaultBoundedRangeModel getBoundedRangeModel(int component)

  Returns the bounded range model of the specified color component.

### getValue

    public int getValue(int component)

  Returns the value of the specified color component.

### setValue

    public void setValue(int component,
                         int value)

  Sets the value of the specified color component.

### getInterpolatedRGB

    public int getInterpolatedRGB(int component,
                                  float ratio)

  Returns an interpolated RGB value by using the values of the color components of this ColorSliderModel except for the component specified as an argument. For this component the ratio between zero and the maximum of its BoundedRangeModel is used.

### addColorSlider

    protected void addColorSlider(javax.swing.JSlider slider)

### removeColorSlider

    protected void removeColorSlider(javax.swing.JSlider slider)

### addChangeListener

    public void addChangeListener(javax.swing.event.ChangeListener l)

### removeChangeListener

    public void removeChangeListener(javax.swing.event.ChangeListener l)

### fireColorChanged

    protected void fireColorChanged(int componentIndex)

### fireStateChanged

    public void fireStateChanged()

### getColor

    public java.awt.Color getColor()

### setColor

    public void setColor(java.awt.Color color)

### setRGB

    public abstract void setRGB(int rgb)

### getRGB

    public abstract int getRGB()

### toRGB

    public abstract int toRGB(int[] values)
