Responds when the VCL representation of the OLE object changes.
procedure Changed; virtual;
virtual __fastcall Changed();
Changed is called automatically so that the associated OLE object can be updated to reflect changes made to the corresponding VCL object. In TCustomAdapter, Changed calls ReleaseOleObject so that the OLE object can be re-acquired to reflect the changes in the VCL object. Descendants of TCustomAdapter override Changed to use the OLE interface to make appropriate changes.
