Working with the Public Interface Editor
In the Composition Editor, you saw that each part is used in a similar way. Each part has attributes, events, and actions that can be connected to other parts to construct your application.
The reusable parts that you create must also have a defined interface so they can be connected easily, in the same way as other VA Smalltalk parts. The Public Interface Editor is used to define that interface.
The Public Interface Editor is a notebook made up of five key visual components: four notebook pages and the visual tool symbols in the bottom-right corner. As you probably remember from other sections, the visual tool symbols allow you to navigate between the visual tools.
Each notebook page is used to edit one aspect of your reusable part's interface. There are four pages: Attribute, Event, Action, and Promote.
In addition to editing interface features, the Public Interface Editor is also used to generate default scripts for your part's attributes, events, and actions.
