When adding tool buttons to a toolbar I noticed a heading under Name and Super called Interfaces with a “Choose…” button. Clicking that button brings up sheet with a bunch of choices. Where can I find information on what these are for?

To understand what class interfaces are and how they work, read Section 5 of the User Guide, “Interfaces”. For details on specific class interfaces, search the Language Ref.

Which user guide? What chapter?

Sorry. Book 1, Fundamentals. You can find it in Xojo’s Help menu.

Thanks for posting :slight_smile:
