 104  * Classes derived from this know how to map from whatever widget they
 105  * find themselves paired with, to the wxProperty and vice versa.
 106  * Should the widget pointer be stored with the validator, or
 107  * the wxProperty? If with the property, we don't have to supply
 108  * a validator for every property. Otherwise, there ALWAYS needs
 109  * to be a validator. On the other hand, not storing a wxWindow pointer
 110  * in the wxProperty is more elegant. Perhaps.
 111  * I think on balance, should put wxWindow pointer into wxProperty.
 112  * After all, wxProperty will often be used to represent the data
 113  * assocated with a window. It's that kinda thing.
