Most PropertyEditors will only need to support a subset of the different options available in this API. <P> Simple PropertyEditors may only support the getAsText and setAsText methods and need not support (say) paintValue or getCustomEditor. More complex types may be unable to support getAsText and setAsText but will instead support paintValue and getCustomEditor. <p> Every propertyEditor must support one or more of the three simple display styles. Thus it can either (1) support isPaintable or (2) both return a non-null String[] from getTags() and return a non-null value from getAsText or (3) simply return a non-null String from getAsText(). <p> Every property editor must support a call on setValue when the argument object is of the type for which this is the corresponding propertyEditor. In addition, each property editor must either support a custom editor, or support setAsText. <p> Each PropertyEditor should have a null constructor.<P><HR><P><!-- ======== INNER CLASS SUMMARY ========
