Using visual annotations with JDT text editor [message #635715]

Hello,

I'd like to highlight certain regions of a JDT text editior (e.g. variables). I think this can be done with annotations and markers and I've started by adding code:

IAnnotationModel annotationModel = editor.getDocumentProvider().getAnnotationModel(editor.getEditorInput());
	    			
Annotation annotation = new Annotation("type", true, "text");
annotationModel.addAnnotation(annotation, new Position(textSelected.getOffset(), textSelected.getLength()));

I'm not sure what "type" and "text" should be. Also, how Markers fit. I guess I could use a standard marker and associate that with those areas of text I would like to highlight but it would be better if I could highlight with squiggly colored lines or similar.

Any pointers to a tutorial or cookbook code to do this would be helpful

Chris
