[news.eclipse.tools.gef] Re: Add new resource to navigator

["Pratik Shah" <none@xxxxxxxxxxx>]

You don't create the resource "in the navigator view."  The navigator view
shows whatever resources are in the workspace, and you just create a
resource in the workspace.

Here's an example from one of our tests that might prove helpful to you:

 // Create the logic file if it doesn't exist
 IWorkspaceRoot root = ResourcesPlugin.getWorkspace().getRoot();
 IProject project = root.getProject(prjName);
 if (!project.exists())
  project.create(null);
 if (!project.isOpen())
  project.open(null);
 file = project.getFile(fileName);
 if (!file.exists()) {
  LogicDiagram diagram = createLogicDiagram();
  ByteArrayOutputStream out = new ByteArrayOutputStream();
  ObjectOutputStream oos = new ObjectOutputStream(out);
  oos.writeObject(diagram);
  oos.close();
  file.create(new ByteArrayInputStream(out.toByteArray()), false, null);
  out.close();
 }

If you're still having problems, I suggest you post on the platform
newsgroup with more details (about what happens when you execute your code
and such), since this is not GEF's domain.
