Hi
i want to drag and drop some items out of a list into the model viewer.
I already can do so but the node is always created at the top left of the viewer and i don't know how to create the node at the dropped location.

Here is the function that creates the node (x and y are the coordinates of the droplocation)

private View addNode(Node node, View deploymentView) {
		
		// use the view service to create the types. This is a bit cleaner than
		// using the sequence-diagram view provider directlys
		final String nodeType = UMLVisualIDRegistry
				.getType(org.eclipse.papyrus.uml.diagram.deployment.edit.parts.NodeEditPart.VISUAL_ID);
		org.eclipse.gmf.runtime.notation.Node nodeView = ViewService.createNode(deploymentView.getDiagram(), node,
				nodeType, UMLDiagramEditorPlugin.DIAGRAM_PREFERENCES_HINT);
		Bounds location = NotationFactory.eINSTANCE.createBounds();

		System.out.println("Dropped at x: "+ (int)this.x + " y: "+ (int)this.y);
		location.setX((int)this.x);
		location.setY((int)this.y);
		return nodeView;
	}

Okay I fixed it.

private View addNode(Node node, View deploymentView) {
		final String nodeType = UMLVisualIDRegistry
				.getType(org.eclipse.papyrus.uml.diagram.deployment.edit.parts.NodeEditPart.VISUAL_ID);
		org.eclipse.gmf.runtime.notation.Node nodeView = ViewService.createNode(deploymentView.getDiagram(), node,
				nodeType, UMLDiagramEditorPlugin.DIAGRAM_PREFERENCES_HINT);
		

		System.out.println("Dropped at x: "+ (int)this.x + " y: "+ (int)this.y);
		
		
		nodeView.setLayoutConstraint(NotationFactory.eINSTANCE
				.createLocation());
		Location location = (Location) nodeView.getLayoutConstraint();
		location.setX((int)this.x);
		location.setY((int)this.y);
		return nodeView;
	}
