'Declaration Public Interface IButtonFactoryPlugIn
public interface IButtonFactoryPlugIn
If your application subclasses TBarButton and adds instances of this subclass to UltraWebToolbar, then you should provide an implementation of this interface to the containing UltraWebToolbar. This permits the Control to create instances of your subclass when necessary to provide serialization and design-time support without having to know explicit details of that subclass (such as its namespace, fully-qualified type, or assembly).
Typically, your implementation of the methods in this interface must only call the constructor of your subclass, and return a new object reference.
