Hover when code isn't selected [message #1816137]

Hi,

In the Java Editor if I put my cursor over a class name I get a hover (if that's the right word?) like the one in the attached screen clipping.

The developer docs have an example for hover such as this:

https://help.eclipse.org/kepler/topic/org.eclipse.platform.doc.isv/guide/editors_hover.htm

But it requires the text to be selected first, rather than simply placing your mouse over the word.

In a plugin I'm writing, what do I need to do in order to replicate that behaviour (ie. the triggering of the hover by placing the mouse in a certain position - I understand I'll need to work what will be displayed when the cursor is in a particular position..).

Thanks,
Andrew.

Probably it's good to look in the source code of some other thing that already does what you want. This tutorial describes how to get all the sources for the whole platform SDK in your workspace.

Likely you'll only really need the JDT parts to see how the Java editor implements this.
