`protected EventListenerList` | `listenerList`

Constructor Summary
`DefaultColorSelectionModel()` Creates a `DefaultColorSelectionModel` with the current color set to `Color.white`.
`DefaultColorSelectionModel(Color color)` Creates a `DefaultColorSelectionModel` with the current color set to `color`, which should be non-`null`.

Method Summary
`void` | `addChangeListener(ChangeListener l)` Adds a `ChangeListener` to the model.
`protected void` | `fireStateChanged()` Runs each `ChangeListener`'s `stateChanged` method.
`ChangeListener[]` | `getChangeListeners()` Returns an array of all the `ChangeListener`s added to this `DefaultColorSelectionModel` with `addChangeListener`.
`Color` | `getSelectedColor()` Returns the selected `Color` which should be non-`null`.
`void` | `removeChangeListener(ChangeListener l)` Removes a `ChangeListener` from the model.
`void` | `setSelectedColor(Color color)` Sets the selected color to `color`.

Field Detail

### changeEvent

    protected transient ChangeEvent changeEvent

  Only one `ChangeEvent` is needed per model instance since the event's only (read-only) state is the source property. The source of events generated here is always "this".

### listenerList

    protected EventListenerList listenerList

Constructor Detail

### DefaultColorSelectionModel

    public DefaultColorSelectionModel()

  Creates a `DefaultColorSelectionModel` with the current color set to `Color.white`. This is the default constructor.

### DefaultColorSelectionModel

    public DefaultColorSelectionModel(Color color)

  Creates a `DefaultColorSelectionModel` with the current color set to `color`, which should be non-`null`. Note that setting the color to `null` is undefined and may have unpredictable results.

Parameters:
  `color` - the new `Color`

Method Detail

### getSelectedColor

    public Color getSelectedColor()

  Returns the selected `Color` which should be non-`null`.

  Specified by:
    `getSelectedColor` in interface `ColorSelectionModel`
  Returns:
    the selected `Color`
  See Also:
    `ColorSelectionModel.setSelectedColor(java.awt.Color)`

### setSelectedColor

    public void setSelectedColor(Color color)

  Sets the selected color to `color`. Note that setting the color to `null` is undefined and may have unpredictable results. This method fires a state changed event if it sets the current color to a new non-`null` color; if the new color is the same as the current color, no event is fired.

  Specified by:
    `setSelectedColor` in interface `ColorSelectionModel`
  Parameters:
    `color` - the new `Color`
  See Also:
    `ColorSelectionModel.getSelectedColor()`, `ColorSelectionModel.addChangeListener(javax.swing.event.ChangeListener)`

### addChangeListener

    public void addChangeListener(ChangeListener l)

  Adds a `ChangeListener` to the model.

  Specified by:
    `addChangeListener` in interface `ColorSelectionModel`
  Parameters:
    `l` - the `ChangeListener` to be added

### removeChangeListener

    public void removeChangeListener(ChangeListener l)

  Removes a `ChangeListener` from the model.

  Specified by:
    `removeChangeListener` in interface `ColorSelectionModel`
  Parameters:
    `l` - the `ChangeListener` to be removed

### getChangeListeners

    public ChangeListener[] getChangeListeners()

  Returns an array of all the `ChangeListener`s added to this `DefaultColorSelectionModel` with `addChangeListener`.

  Returns:
    all of the `ChangeListener`s added, or an empty array if no listeners have been added
  Since:
    1.4

### fireStateChanged

    protected void fireStateChanged()

  Runs each `ChangeListener`'s `stateChanged` method.

  See Also:
    `EventListenerList`
