setting text markers on a resource [message #151612]

Hi,
I'm posting thsi both on platform and tools.cdt because as far as I
understand it involves both.

I want to highlight a line of C code for a file being shown in a CDT
editor. Given the IFile retrieved from the workspace, I do the following:

IMarker m = file.createMaker(IMarker.TEXT);
m.setAttribute(IMarker.LINE_NUMBER, linenum);

As far as I understand if an editor is opened on file I should see line
linenum highlighted in it. CDT's CEditor seems to be a subclass of
TextEditor, so it should behave accordingly. Instead, I don't see
anything being highlighted in the editor.

Am I missing something?

Thanks,
Roberto

Yes, you need
IDE.gotoMarker(editor, marker);
(See response to your first post in CDT newsgroup above)
