[edit] Development concepts

The fundamental concepts in Forms are:

  • A canvas is an area for “painting” the various items and labels that provide the user interface.
  • A block is often based on, and corresponds to, a database table. Forms is most useful when used to provide operations that conform to the fundamental ‘SELECT, INSERT, UPDATE, DELETE’ concepts.

Coding generally hangs off triggers based around these events, or around user events (such as pressing a button or moving to a different field).
