I’m new-ish to Interfaces in Delphi, but not new to Delphi, having used it since the heady days of Delphi 1!

I am trying to implement the Builder design pattern in Delphi using records. My goal is to allow chaining of methods, similar to how it’s done in Kotlin, Java, or Swift. For example:

I was previously using Delphi 7 and it had the normal codebar and QRcode, when I used Delphi 11 VCL and wanted to print a report using FastReport, I found only the normal codebar, I could not find the QRCode in the obCatBarcode field inside the report.
Do you have any idea how I can display QRCode in a report, without using external libraries?
