Hi
Does anyone know if there's a way to test for interface inheritance?
For example
IFirstDescendant = interface(IInterface);
ISecondDescendant = interface(IFirstDescendant);
TNewClass = class(TInterfacedObject,ISecondDescendant);
NewObject = TNewClass.Create;
is there a way to see whether NewObject supports the interface
"IFirstDescendant"
NewObject.GetInterface(IFirstDescendant,Descendant)
returns a nil pointer for Descendant.
I'm thinking the VTable entry for the ISecondDescendant interface, might
link back to IFirstDescendant somehow.
Todd.
