Hi,
How does the JDT draw the box (the blue box in the attached image)
around the text area? I would greatly appreciate it if someone points
me the JDT code that does this.
please see attached image.
Thanks

Thanks very much, Tom, for the tips! I would prefer to use the jface
text framework because my editor is already using ISourceViewer, etc.

Sorry...One more question...I look at the documentation, and it says to
use SourceViewerDecorationSupport class which has all kinds of
strategies, including drawing the box around the text, the squiggly
line, etc.
my question is: How and/or under what conditions I kick start these
strategies? That is, what do I have to do to cause the drawing to start
and to reset the drawing?

This is automatically done if you add or remove your annotations.

Oh, boy...I am still quite lost. I've been reading documentation and
that I can create a SourceViewerDecorationSupport and associate it to my
source viewer.
All I want to do is to draw a red box around a text range. I see that
SourceViewerDecorationSupport has the box strategy to draw the box
around a text range.
(1) How do I create the box annotation? I look at the Annotation class
and I can't find the annotation type id (a string) that represents the
box drawing strategy. Do I have to define extension points?
(2) where to I add and remove the annotation?
Thanks.

Yep, see org.eclipse.ui.editors.annotationTypes and
org.eclipse.ui.editors.markerAnnotationSpecification extension points.
There you can specify BOX text style.

On the annotation model (which you get from your document provider).

thanks again for the response...My scenerio is that I don't use the
documentation provider at all. I "embed" my source viewer (editable) in
a layout, just like how the JDT shows when you do
"Preferences->Java-Editor->Syntax Coloring".
Can I simply create the IAnnotationModel (that is, AnnotationModel
class) and connect it to my IDocument? But the question is: What is
the relationship with the annotation model and the source view and/or
the source viewer configuration? When I do
IAnnotationModel.addAnnotation(...), how would the source viewer to told
to do the box?
Thanks so much for your help so far.

I see ISourceViewer#setDocument(IDocument, IAnnotationModel, int, int).
I can set my own annotation model, even though the annotation model
in the org.eclipse.jface.text.source.SourceViewer, which my source
viewer derives off, says that it is for the ruler annotation. Sounds
like the right usage?
thanks.
