Example text

Therefore, no matter what concrete type each component actually is, the generic type is still the same. With that scheme, we can treat each of them uniformly when we use them. If the component is just a single dot, then it will be rendered as a filled circle to represent a “dot” onscreen. But if it’s a series of dots (vertices) with which they are supposed to be connected together as a group of entities, then they will be plotted as a connected line (stroke). That is the distinction between them.

But before we dive into a design phase, we should make sure we have the look-and-feel of it so we can get a pretty good idea about what the app should look like. Let’s summarize our first-ever requirements for our wonderful drawing app: A drawing pad allows scribbling with the user’s finger. It allows the user to change stroke colors and sizes. It allows the user to save a scribble. It allows the user to open a saved scribble. CHAPTER 2: A Case Study: Designing an App It allows the user to delete the current scribble.

I do hope that this chapter has been a good warm-up for the real flesh in the upcoming chapters. 19 Chapter 2 A Case Study: Designing an App Just like the next top-paid app in the app store, we need some good ideas to start with. The good idea we are going to use for this book example is a drawing app. We call it TouchPainter. It is simple yet comprehensive enough to showcase many design patterns and best practices. We will go through several design phases, and during each process we will come up with some requirements, use cases, and problems related to our design.
