Hello,

I am using customized labels for my Xtext grammar . I want to add clickable labels(references to already defined elements) to some other elements so that I can navigate to my declared definitions. Is this possible with xtext? I have searched LabelProvider but it only take String as parameter.

eg.

Class A;

Class B extends A;

When I hover on class B , I can see "A" in the label. However,I want to make this label as a link(cross reference) to my declaration.

Thanks in advance.

Why do you want to click in hover and not use the default open declaration mechanism
(F3 or crtl+Click)

I am using the customized labels and want to make them clickable. Is there any alternative(any region) where I can show my list of referenced elements to the user, where they can click on them and navigate to the element declaration. I have the requirement similar to the forum https://www.eclipse.org/forums/index.php/t/1091374/

Any help will be appreciated.

Thanks in advance.

Yeah, I understand you but I have one question. I can get the names for the element using the element's name feature or name attribute. This element reference(which also contains the name feature) comes from Xtext. I need to know if there exists a library in Xtext which can pass these value to other module say rcp.

i dont understand the hover is html.
you can get elements names, references, eresources, uris (and thus ifliles)
if you want to do this via label in hover and not via open declaration you need to find out:

"how do i make my hover open a link/editor inside eclipse"

=> if you are able to open myproject/a.txt then you can open b.mydsl as well
