Tips for lames

I'm lame GMF user and I find those tips useful:

Creating new Elements and corresponding Views

DeviceEditPart selectedElement = ...;

String compartemntsSemanticHint = NetworkVisualIDRegistry.getType(tests.mindmap.network.diagram.edit.parts.Device_ModulesCompartmentEditPart.VISUAL_ID);
Device_ModulesCompartmentEditPart modulesCompartment = (Device_ModulesCompartmentEditPart)selectedElement.getChildBySemanticHint(compartemntsSemanticHint);

IElementType type = NetworkElementTypes.Module_3001;

ViewAndElementDescriptor viewDescriptor = new ViewAndElementDescriptor(
	new CreateElementRequestAdapter(new CreateElementRequest(type)),
	Node.class,
	((IHintedType) type).getSemanticHint(), 
	selectedElement.getDiagramPreferencesHint());

CreateViewAndElementRequest req = new CreateViewAndElementRequest(viewDescriptor);

CompoundCommand cmd = new CompoundCommand("Tworzenie dziesięciu modułów");
for (int i=0; i<1; i++) {
	cmd.add(modulesCompartment.getCommand(req));
}

selectedElement.getDiagramEditDomain().getDiagramCommandStack().execute(cmd);
Collection results = DiagramCommandStack.getReturnValues(cmd);
for (Object res: results) {
	if (res instanceof IAdaptable) {
		IAdaptable adapter = (IAdaptable) res;
		View view = (View) adapter.getAdapter(View.class);
		if (view != null) {
			Module newMod = (Module)view.getElement();
			SetRequest reqSet = new SetRequest(selectedElement.getEditingDomain(),
				newMod, NetworkPackage.eINSTANCE.getNamedElement_Name(),
				"ModX");
			SetValueCommand operation = new SetValueCommand(reqSet);
			selectedElement.getDiagramEditDomain().getDiagramCommandStack().execute(new 
				EtoolsProxyCommand(operation));
		}
	}
}

more will be soon.
