In this chapter, we're going to create custom editors and views in plug-ins. Plug-in development is a huge topic by itself, and it can take dozens of files to create a commercial plug-in. Fortunately, the Eclipse PDE comes with a number of wizards that will write up the plug-in's code framework for you, saving significant time. We'll see how to use those wizards in this chapter, rewriting the code they generate to make the plug-in do what we want.
