Excerpt of article text...

One of the new interface elements that has emerged over the past half-decade or so is the auto-completing EditField, which analyzes what is being typed and, if it matches the first portion of an item from a list, completes the typing for the user.

These gadgets first became popular in web browsers, where they allow users to just type the first portion of a URL that they had recently visited. Apple uses this type of EditField in many programs, most visibly iTunes and Mail.

This is the type of thing that's screaming to be a subclass in REALbasic: an extension of an existing control that provides some extra features. We can subclass REALbasic's EditField class pretty easily -- the process will involve adding an array of strings to serve as the list, and the coding to make it do lookups and autocompletions.
