Eclipse RCP: Does CNF without IDE plug-in require custom ContentProvider?

In an RCP application, I'd like to create a Common Navigator Framework view, starting just with resources on the local file system.

I've done that in one project that includes the org.eclipse.ui.ide plug-in. However, that creates a UI that is over-complex and inappropriate for this application. (For example, it adds about 20 preferences panels, some associated with builds and version control.)

So now I'm trying to do it without the ~.ide plug-in -- and without the org.eclipse.ui.navigator.resources plug-in which depends on it.

In the RCP app, I've managed to create a new workspace project (I think) with the code below, in a plugin with the ~navigator.viewer extensions shown below. But nothing appears in the CNF view.

Questions:

  • Since I am excluding the org.eclipse.ui.navigator.resources plug-in, do I need to define my own content provider?
  • Is the class ResourceExtensionContentProvider in the org.eclipse.ui.navigator.resources plug-in used to implement the content binding org.eclipse.ui.navigator.resourceContent?

Code used to create a new project (included for completeness):

        Path path = new Path( sPath );
        File filePath = new File( sPath );
        String fileBaseName = filePath.getName();
        String projectName = fileBaseName; // For now

        IWorkspace workspace = ResourcesPlugin.getWorkspace();
        IProjectDescription projDescr = workspace.newProjectDescription( projectName );
        projDescr.setLocation( path );

        IWorkspaceRoot root = workspace.getRoot();
        IProject project = root.getProject( projectName );

        try {
            project.create( projDescr, null );

            if ( ! project.isOpen() ) {
                project.open( null );
            }
        } catch (CoreException e) {
             MessageDialog.openError( Display.getCurrent().getActiveShell(),
                     "New Project Error", "Could not create new project." + "\n[" + e + "]");
        }


Instead of using the CommonNavigator class, you need to extend it and then override the getInitialInput() method. There return IWorkspaceRoot
