I know SWT has a Link class to create HTML a href style links as widgets, but I wast trying to find a way to make certain text in a StyledText control appear and function as a link.
I feel like Eclipse does this in their code editor if you hold down control and hover over a method name, but I know the Eclipse java editor is much more complicated than a StyledText control.
Since JFace 3.5, there is a special style for links:
This makes it much more simple to identify a link and you can store the URL in the style. As for automatically finding links, just look for the pattern
http://[^ ](blanks are not allowed in links) in the lines you get and add the style.
