Excerpt of article text...

Last spring I gave a presentation on design patterns at the Xojo Conference in London. I thought it might be nice to do a write-up in xDev on the topic.

While my initial articles will cover the patterns I talked about in my presentation, I may expand this series to additional patterns if there's interest.

Before We Begin

Before I did my presentation I knew little about design patterns. I had read about some and had a vague understanding, and I'd even used a few, but I didn't truly understand them at their core.

One surprising thing I discovered is that to really "get" patterns, you need a solid foundation of Object-Oriented Programming (OOP). That's because patterns are a key OOP feature. Also, the entire purpose of design patterns are to help you use OOP better, so if you don't know or use OOP, patterns are pointless for you.

Thus, we will begin this series with a quick refresher on Object-Oriented Programming.
