Hi,
Starting from an instance of papyrusmultidiagrameditor, I would like to select a given diagram, to select a list of elements in this diagram and to reveal them.

Is there an API for this ? If not, how can I achieve it ?
I want to select SysML elements existing in the model and make them appear programmatically in a diagram .

Sami.

Hi!

I can list the existing diagrams with the following function

public List<Diagram> getDiagrams(){
		try{
			Resource notationResource;
			notationResource = NotationUtils.getNotationModel(this.editor.getServicesRegistry().getService(ModelSet.class)).getResource();
			@SuppressWarnings("unchecked")
			List<Diagram> list = (List<Diagram>)(List<?>) notationResource.getContents();
			return list;
		}catch(ServiceException e){
			throw new RuntimeException(e);
		}
	}

Here the editor is your IMultiDiagramEditor instance.

Hi, András,

A bit of care is needed, here. The notation resource can also have as roots:

* tables, instances of the NattablePackage.Literals.TABLE class
* embedded stylesheets, instances of the
StylesheetsPackage.Literals.STYLESHEET class

and possibly other things (I think I've seen other objects, but I
forget what). In any case, some judicious filtering of the resource's
contents is recommended.

Coming in the M6 milestone of the Neon release will be a new API of the
IEMFModel interface (which the NotationModel implements): the
getRootElements() operation provides an iteration of all the logical
roots of the model, which in this case is notations. That includes
both diagrams and tables, but not other things like stylesheets. So,
some filtering still needed, but perhaps your use case does actually
need to account for tables, too (I don't know).

Cheers,

Christian

Hi,

The OpenElementService (Used to open e.g. Search Results in Papyrus) can help here. If you give it either a Semantic element (UML) or graphical element (Notation), it will:

- Find representations of this element (This step can be skipped if you use a graphical element directly)
- Open or focus the proper editor for this representation (Usually a Diagram editor)
- Select and Focus the representation (Ensuring it is visible on screen, moving the scrollbars as necessary)

The code looks like:

IMultiDiagramEditor editor;
OpenElementService openService = editor.getServicesRegistry().getService(OpenElementService.class);
openService.openElement(viewElement); //If you already have the representation (notation::View)
openService.openSemanticElement(semanticElement); //If you only know the semantic (UML) element

HTH,
Camille
