I am newbie with Eclipse e4 and to build an 100% e4 aplication. I can doa lot but on Property I have a problem:

I have an EMF Model , I generated the Java classes of my model the edit and editor plugins.
In my application I have an explorer, and when I select an object in the explorere I can for example do a graphic represenntaion of it (). But I can't sett it in a "Property Page". I mmust recognize that I havee diffculties to understand the generated code in .editor.

My part Propety is build with 2 columns "Property" and"Value" bu thhe items when Ii selct an object in the explorer, I don't unbeecauauss Igo through

myProperty.handleEntrySelection(ExplorerPart.getTreeViewer().getSelection()); avec la bon objet.

Here is my code:


import galera.supports.provider.SupportsItemProviderAdapterFactory;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Vector;

import javax.annotation.PostConstruct;
import javax.inject.Inject;
import javax.inject.Named;

import org.eclipse.e4.core.di.annotations.Optional;
import org.eclipse.e4.ui.di.Focus;
import org.eclipse.emf.common.command.BasicCommandStack;
import org.eclipse.emf.ecore.resource.Resource;
import org.eclipse.emf.edit.domain.AdapterFactoryEditingDomain;
import org.eclipse.emf.edit.provider.ComposedAdapterFactory;
import org.eclipse.emf.edit.provider.ReflectiveItemProviderAdapterFactory;
import org.eclipse.emf.edit.provider.resource.ResourceItemProviderAdapterFactory;
import org.eclipse.emf.edit.ui.provider.AdapterFactoryContentProvider;
import org.eclipse.emf.edit.ui.view.ExtendedPropertySheetPage;
import org.eclipse.jface.viewers.ISelection;
import org.eclipse.jface.viewers.IStructuredSelection;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.ui.IActionBars;

public class PropertiesEditorPart {

ExtendedPropertySheetPage myProperty;
private AdapterFactoryEditingDomain editingDomain;
ComposedAdapterFactory adapterFactory;
List<PropertySheetPage> propertySheetPages = new ArrayList<PropertySheetPage>();

public void createComposite(Composite parent) {
ComposedAdapterFactory adapterFactory = new ComposedAdapterFactory(ComposedAdapterFactory.Descriptor.Registry.INSTANCE);

adapterFactory.addAdapterFactory(new ResourceItemProviderAdapterFactory());
adapterFactory.addAdapterFactory(new SupportsItemProviderAdapterFactory());
adapterFactory.addAdapterFactory(new ReflectiveItemProviderAdapterFactory());

// Create the command stack that will notify this editor as commands are executed.
BasicCommandStack commandStack = new BasicCommandStack();

// Create the editing domain with a special command stack.
editingDomain = new AdapterFactoryEditingDomain(adapterFactory, commandStack, new HashMap<Resource, Boolean>());
parent.setLayout(new FillLayout());
myProperty = new ExtendedPropertySheetPage(editingDomain){
public void setSelectionToViewer(List<?> selection) {

public void setActionBars(IActionBars actionBars) {

public void handleEntrySelection(ISelection selection)
if (!selection.isEmpty() && selection instanceof IStructuredSelection) {
IStructuredSelection structuredSelection = (IStructuredSelection)selection;

if (structuredSelection.size() == 1)
Vector<ISelection> v = new Vector<ISelection>();
Object object = structuredSelection.getFirstElement();


IPropertySourceProvider provider = new AdapterFactoryContentProvider(adapterFactory);


public boolean setFocus() {
if(myProperty != null) return myProperty.getControl().setFocus();
return false;

public void receiveSelection(@Optional @Named(IServiceConstants.ACTIVE_SELECTION) Object o) {
if(o != null) {
if(myProperty != null) {

Can you please clarify what is exactly your problem?

FYI, a pure E4 application can't use anything in org.eclipse.ui.*.

My part Propety is build with 2 columns "Property" and"Value", I create it in Application.e4xmi.

My Explorer work fine, If select an item in it, I go through the method "receiveSelection". In this method I call myProperty.handleEntrySelection(ExplorerPart.getTreeViewer().getSelection()); with the select item. Has I have set SupportsItemProviderAdapterFactory() in my editingDomain. I was thinking that the propertyPage will set all object (attributs, ....) has they are part of SupportsItem. But in my property page I have nothing.

In reality my problem is to try to reuse the .edit features in my application. And I must recognize that this is not clear for me.

Thanks for your help
