completion (Eclipse 3.1.1)?
Can anyone give me some direction? I'm pretty new to the source code and am
trying to work through the jdt packages, but there is a lot there.
Any help is appreciated.

Greg,
In your editor's main class, the one that extends the TextEditor class,
override the method getContentAssistant, which returns the
IContentAssistant, your content assistant that implements the
IContentAssistant. So, the code would be something like the below.
public IContentAssistant getContentAssistant()
{
return
this.getSourceViewerConfiguration().getContentAssistant(this .getSourceViewer());
}
This is only half of the battle. As you can see, you will have first to
create your own source viewer configuration. Your source viewer can
simply extend the Eclipse class SourceViewerConfiguration and override
the method SourceViewerConfiguration.getContentAssistant() to return
YOUR content assistant for your editor. In this getContentAssistant()
method, you can simply create and return a ContentAssistant or
ContentAssistant2 instance, all of which implements the
IContentAssistant. Make sure to set the completion processor for the
assistant object you created. It's best to have your content assistant
as a data member of your source configuration class so that you won't be
creating new content assistant instances, as the getContentAssistant()
does get called a lot! Explore the ContentAssist api calls.
The next thing is to implement your completion processor. You basically
have a clas that implements IContentAssistProcessor. The most important
methods to implement are the getCompletionAutoActivationCharacters() and
computeCompletionProposals that returns an array of
ICompletionProposal for Eclipse display in the list!
Good luck!
