Provides the underlying implementation for the CanAddClass method.

Pascal
function ImplCanAddClass(AParent: TComponent; AClass: TClass): Boolean; override;
C++
virtual __fastcall Boolean ImplCanAddClass(TComponent * AParent, TClass AClass);
Description

The CanAddClass method calls ImpleCanAddClass to determine whether the TWebForm descendant can add a component of type AClass to its WebComponents property list. AParent is the TWebForm instance to which the component will be added. 

In TWebForm, ImplCanAddClass is abstract or, in C++ terminology, pure virtual. TWebForm descendants must override ImplCanAddClass to indicate what types of Web Items they can use when generating their HTML forms.
