Excerpt of article text...

Lately I've been covering some fairly advanced beginner topics, so I've decided to take a moment to cover the obvious. Often the most simple things are not well documented or publicly explained and present awkward obstacles for those just starting out.

As one simple example, I remember when I first used REALbasic being puzzled about how to group radio buttons together. If I just had one group on a window it worked fine, but two or more groups didn't as they still acted like one group. It was a while before I realized I had to group the radio buttons inside a GroupBox for them to work in sync.

So today we're going to begin an exploration of some of the most basic of REALbasic controls. Much of this may be obvious to you, but hopefully you'll find at least one or two nuggets of new information.

Shared Basics

We'll begin by covering the most basic aspects of basic controls. In the past we've talked about the object-oriented principle of inheritance -- that's how you're able to create custom subclasses of existing controls, for instance. If you look through most controls you'll see they're all based on a generic object called RectControl.
