Update on Interfaces in Delphi

Posted by Kirby Turner on May 4, 2005

After taking a break from the laptop I was able to get a much better handle on interfaces in Delphi. And I was able to implement the design I wanted. It’s not as slick as in C# but it works. And the code is readable, which is important to me.

I was returning a TObject when I should have been returning IInterface. After seeing the code it makes sense to me why my use of TObject was causing problems, and why I was trying to cast an interface from an object, which now I see was not needed.
