How to access the Test.Apportioning property above?

array delphi property

  • It is not clear what you want. If Teste is a variable of the type TTeste and just want to access, it would be something like Teste.Rateio[0].Agencia. Are you having any problems with this code? Which?

I think you made the mistake of putting the Tarrayofrateio type of power instead of Trecordrateio.

If you change to 

 property Rateio[AIndex : Integer] : TRecordRateio read GetRateio Write SetRateio; default;

and the respective Set and Get to receive and send a Trecordappy, you will have the registration accessible.
