public class DefaultColorSelectionModel extends Object implements ColorSelectionModel, Serializable
A generic implementation of ColorSelectionModel
.
Color
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".
protected EventListenerList listenerList
public DefaultColorSelectionModel()
Creates a DefaultColorSelectionModel
with the current color set to Color.white
. This is the default constructor.
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.

. 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.
