Field Details

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

The listener list.

Constructor Details

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 Details

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:

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:

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 ChangeListeners added to this DefaultColorSelectionModel with addChangeListener.

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

fireStateChanged

protected void fireStateChanged()

Runs each ChangeListener's stateChanged method.
