Is displaying part of GMF model possible? [message #902089]

Is this even possible?

I am working on a project with GMF models. I have a whole Diagram object, that represents my *.ecorediag" file. But I do not want to display the whole diagram. Rather I want to display only One Node and it's persistent Children.

Currently I am doing:

	private DiagramGraphicalViewer viewer;
	protected final void displayDiagram(final Diagram diag) {

		if (diag == null) {
			return;
		}

		currentDiag = diag;
		
		// be sure the viewer will be correctly refreshed ( connections )
		viewer.getEditPartRegistry().clear();
		final DiagramRootEditPart rootEditPart = new DiagramRootEditPart(
				diag.getMeasurementUnit());
		viewer.setRootEditPart(rootEditPart);
		viewer.setContents(diag);

		enableEditMode((DiagramEditPart) viewer.getContents());
		rootEditPart.getZoomManager().setZoomAnimationStyle(
				ZoomManager.ANIMATE_NEVER);
		rootEditPart.getZoomManager().setZoom(ZOOM_FACTOR);
}

If so how can I do diag.getPersistantChildren().get(0), and view only those children?

Hi,

is it a solution for you to set all other views to invisible in notation model?

How do I set other views to invisible?

I try to edit the

Diagram diag

object, to make some of the elements hidden. I get the error "Cannot modify resource set without a write transaction."

Is there a way to display a model in a view?
A minimalist way?

Hi,

you should try to use EMF Commands and execute them. Try SetCommand.create() http://download.eclipse.org/modeling/emf/emf/javadoc/2.4.2/org/eclipse/emf/edit/command/SetCommand.html#create(org.eclipse.emf.edit.domain.EditingDomain, java.lang.Object, java.lang.Object, java.lang.Object, int) to create an instance of the command. Execute this on the editdomain of the resource of the notation model. If you need further assistance let me know. It would be helpful to know where you want to execute the code.

I am trying to execute the command after I run the constructor and create a tab new tab. Here is my constructor:

	public DiagramViewerTab(Composite parent, int side,
			GMFContentMergeTabFolder parentFolder) {

		contentMergeTabFolderParent = parentFolder;
		partSide = side;
		editDomain = new DiagramEditDomain(null);
		editDomain.setCommandStack(new DiagramCommandStack(editDomain));

		createDiagramGraphicalViewer(parent);

	}

	private void createDiagramGraphicalViewer(Composite composite) {
		viewer = new DiagramGraphicalViewer();
		viewer.createControl(composite);
		viewer.setEditDomain(editDomain);
		viewer.setEditPartFactory(EditPartService.getInstance());
		viewer.getControl().setBackground(ColorConstants.listBackground);
		viewer.setProperty(MouseWheelHandler.KeyGenerator.getKey(SWT.CTRL),
				MouseWheelZoomHandler.SINGLETON);
	}

Then after I load my Diagram into memory. I call displayDiagram(Diagram diag).

Thanks for the help!
