[ECP] ECP and element links inside widgets [message #1633143]

Hello,
I am using ECP to display a set of numbered articles (where an article is just a paragraph of text) .
The articles are organized by chapters and sub chapters. And I have an ecore model that represents this. So I can navigate my text like a tree structure using ECP. (e.g. chapter 1, subchapter 2, might contain articles 5 to 10)

When I display my articles I display them with a standard text area control.
It is very common that an article might refer to another article.For example article 100 might say " for blah blah blah refer to article 200"
When I display" for blah blah blah refer to article 200" I would like to be able to have 'article 200' underlined in the text and have the equivalent of a hyperlink which will open the model element for article 200 when I click on the underlined text.
Any ideas on how this could be done with ECP (I need it to work with RAP)
Perhaps a custom control based on the swt Link widget?(e.g. http://www.java2s.com/Code/Java/SWT-JFace-Eclipse/Createalinkwidget.htm)
This is probably not a very conventional use of ECP, and might seem better suited to html, but I am interested in the links between paragraphs for navigation and also for analysis (so my ecore model will contain the crossreferences between articles).
Thanks in advance for any tips.
Neil

Hi Neil,
I would implement this as a special renderer based on the AbstractControlSWTRenderer class.
In the renderer you can then use the link widget.
This should do the trick.

Cheers,
Eugen
