Once an object is based on a property class, you can modify the definition of the object or its property class by doing any of the following:
Properties that inherit their value from a property class are displayed with an arrow symbol in front of the property name. Once an object is based on a class, you can override the setting of any inherited property to make that property variant. Variant properties and properties for which there is no corresponding property in the class are displayed normally, without the arrow symbol.
