PropertyEditorSupport is returned.public void setSource(Object source)
The source bean is used as the source of events for the property changes. This source should be used for information purposes only and should not be modified by the PropertyEditor.

setValue in interface PropertyEditorvalue - The new target object to be edited. Note that this
object should not be modified by the PropertyEditor, rather
the PropertyEditor should create a new object to hold any
modified value.public Object getValue()

If the PropertyEditor doesn't honor paint requests (see isPaintable) this method should be a silent noop.

Example results are "2", "new Color(127,127,34)", "Color.orange", etc.
getJavaInitializationString in interface PropertyEditorpublic String getAsText()
getAsText in interface PropertyEditorReturns null if the value can't be expressed as a string.
If a non-null value is returned, then the PropertyEditor should be prepared to parse that string back in setAsText().

PropertyChangeEvent
on all registered PropertyChangeListeners,
specifying the null value for the property name.
If the source property is set,
it should be used as the source of the event.
The same listener object may be added more than once,
and will be called as many times as it is added.
If listener is null,
no exception is thrown and no action is taken.

If the same listener was added more than once,
it will be notified one less time after being removed.
If listener is null, or was never added,
no exception is thrown and no action is taken.
