Loaded and removing methods
Your application includes a special class that always has the same name as the application itself. For example, MyRunSamplePartsApp contains a class called MyRunSamplePartsApp, and MyEditSamplePartsApp contains a class called MyEditSamplePartsApp. These classes include special methods that run when the application is loaded or removed from a VA Smalltalk image. These methods are named loaded and removing. The loaded method is a good place to do things like the following: 
•Add your parts to the Composition Editor's parts palette. 
•Load any message files that your parts use. 
•Initialize class variables. 
The removing method is a good place to do things like: 
•Remove your parts from the Composition Editor's parts palette. 
•Unregister any message files you loaded. 
You will be working primarily with your edit-time application to accomplish these tasks. In the Organizer, select MyEditSamplePartsApp and then open the MyEditSamplePartsApp part. 
Now, let's look at some examples.
