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.

- setSelectedColor in interface ColorSelectionModel
- Parameters:
- color - the new Color

- 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 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
