 102  * Should the widget pointer be stored with the validator, or
 103  * the wxProperty? If with the property, we don't have to supply
 104  * a validator for every property. Otherwise, there ALWAYS needs
 105  * to be a validator. On the other hand, not storing a wxWindow pointer
 106  * in the wxProperty is more elegant. Perhaps.
 107  * I think on balance, should put wxWindow pointer into wxProperty.
 108  * After all, wxProperty will often be used to represent the data
 109  * assocated with a window. It's that kinda thing.
