Class ColorSelectionAdapter
DefaultColorSelectionModelcom.jgoodies.binding.adapter.ColorSelectionAdapter
public final class ColorSelectionAdapter
extends DefaultColorSelectionModel
Converts ValueModels to the ColorSelectionModel interface. Useful to bind
JColorChooser and similar classes to a ValueModel.
Constraints: The subject ValueModel must be of type Color
and must allow read-access to its value. Also, it is strongly recommended
(though not required) that the underlying ValueModel provides only non-null
values. This is so because the ColorSelectionModel behavior is undefined
for
null values and it may have unpredictable results.
Examples:
// Recommended binding style using a factory
ValueModel model = presentationModel.getModel(MyBean.PROPERTYNAME_COLOR);
JColorChooser colorChooser = BasicComponentFactory.createColorChooser(model);
// Binding using the Bindings class
ValueModel model = presentationModel.getModel(MyBean.PROPERTYNAME_COLOR);
JColorChooser colorChooser = new JColorChooser();
Bindings.bind(colorChooser, model);
// Hand-made binding
ValueModel model = presentationModel.getModel(MyBean.PROPERTYNAME_COLOR);
JColorChooser colorChooser = new JColorChooser(new ColorSelectionAdapter(model));

ColorSelectionAdapter
public ColorSelectionAdapter(ValueModel subject)
Constructs a ColorSelectionAdapter on the given subject ValueModel.
subject - the subject that holds the value
ColorSelectionAdapter
public ColorSelectionAdapter(ValueModel subject,
Color defaultColor) Constructs a ColorSelectionAdapter on the given subject ValueModel.
subject - the subject that holds the valuedefaultColor - an optional default color that is used as
selected color if the subject returns null
getSelectedColor
public Color getSelectedColor()
Returns the selected Color which should be non-null.
The return value is the subject value model's value, if non-null,
otherwise the default color. Note that the latter may be null too.
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.
