I am developing an Eclipse plugin that has a view with several sections in
it. In one of these sections is a list of source files with line numbers
associated with them (e.g. "SomeClass.java, line 643"). What I want to
know how to do is make it so that when a user clicks on one of these, the
editor will go to that source file and that line.
I already know how to make a list or link that has a SelectionListener
that executes a function when you click on it, but I need to know what the
command is to tell the editor to go to a particular line of a particular
source file.
Essentially, I want to do exactly the same thing that the built-in
Problems view does (i.e. open an editor for the target file, or go to it
if there already is one, and go to a particular place in that file),
except that there is not necessarily a marker at the target line.

Hi Alexander
Try something along the line of:
((ITextEditor)org.eclipse.jdt.ui.JavaUI.openInEditor(compila tionUnit)).selectAndReveal(int,
int);

Once you have the source file you can get the cu through:
org.eclipse.jdt.core.JavaCore.create(IFile)
I don't know how to obtain the file. If you have a fully qualified file
name you could use
ResourcePlugin.getWorkspace().getRoot().findMember(IPath) if you do not
have the fully qualified name then you must search the file in the
workspace. This would be slow, and of course you could have multiple
matches.
