[wiki:gmf:gmf <back]

  1. Create new view with a normal TreeViewer (for example)
  1. Use {{{AdapterFactoryContentProvider}}} as content provider and {{{AdapterFactoryLabelProvider}}} as label provider. It should be something like that:[[BR]]
{{{
#!cpp
AdapterFactory adapterFactory = ExhibitionDiagramEditorPlugin
	.getInstance().getItemProvidersAdapterFactory();
viewer.setContentProvider(new AdapterFactoryContentProvider(adapterFactory));
viewer.setLabelProvider(new AdapterFactoryLabelProvider(adapterFactory));
}}}
  1. Set the input of the viewer like that: (Maybe there is a better way, but I didn't found it yet...)[[BR]]
{{{
IEditorPart edp = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().getActiveEditor();
viewer.setInput(((DiagramDocumentEditor)edp).getEditingDomain().getResourceSet());
}}} 
  1. You can inherit from the content and label provider to customize them for your needs.
  1. Notice: the viewer will only update the objects that it contains. If you for example omit the top-level node, the viewer will not notice if you add or remove a childnode of the top-level node.

If you want the properties view to listen to selection changes of the viewer do the following:
  1. The view must implement {{{ITabbedPropertySheetPageContributor}}}
  2. The method {{{getContributorId()}}} must return the ID that is returned by {{{getContributorId()}}} of your XXXDiagramEditor class.
  3. Implement the method {{{getAdapter}}} similar to the following:
{{{
public Object getAdapter(Class type) {
    if (type == IPropertySheetPage.class) {
       return new PropertiesBrowserPage(this);
    }
    return super.getAdapter(type);
}
}}}
  1. In {{{createPartControl}}} add {{{getSite().setSelectionProvider(viewer);}}} where {{{viewer}}} is your TreeViewer.
  1. Probably you have to add something like {{{<input type="org.eclipse.emf.ecore.EObject"/>}}} to the plugin.xml for the extension point {{{org.eclipse.ui.views.properties.tabbed.propertySections}}}.
