Hi,
What does it take for a class to access a field using FieldAddress(...)?
I have tried with both typeinfo on/off ({M+}), placing the field in
private/protected/public/published
sections but to no avail.
My simple code is:
TMyObject = class
private
FRef: TMyObject;
procedure SetRef(AValue: TMyObject);
public
property Ref: TMyObject read FRef write SetRef;
end;
then i have tried to get the adress in two ways:
AMyObject.FieldAddress('FRef'); //returns nil
AMyObject.FieldAddress('Ref'); //also returns nil
If i run my code through debugger, the VMT FieldTable is empty
suggesting no information is
created. This happens in all cases of typeinfo on/off and differenc
sections...
What can i do to make the fieldadress accessible?
Regards,
Torsten.
