Hi!

Im trying to open the model explorer and selecting a model element in it using the XMI-ID.

Here is the code that I have so far:

    public void showTracePoint(TracePoint tp) {
        // create editor input
        FileEditorInput fileEditorInput = createFileEditorInput(tp.getResourceID());
        // open editor
        PapyrusMultiDiagramEditor papyrusMultiDiagramEditor = null;
        try {
            papyrusMultiDiagramEditor = (PapyrusMultiDiagramEditor) PlatformUI
                    .getWorkbench().getActiveWorkbenchWindow().getActivePage()
                    .openEditor(fileEditorInput, EDITOR_ID);
        } catch (PartInitException e) {
            Activator.logError(e);
        }
        // open explorer
        ModelExplorerPageBookView modelExplorerPageBookView = null;
        try {
            modelExplorerPageBookView = (ModelExplorerPageBookView) PlatformUI
                    .getWorkbench().getActiveWorkbenchWindow().getActivePage()
                    .showView(EXPLORER_ID);
        } catch (PartInitException e) {
            Activator.logError(e);
        }
        // obtain model element
        EObject model = null;
        try {
            model = UmlUtils.getUmlModel().lookupRoot();
        } catch (NotFoundException e) {
            Activator.logError(e);
        }
        if (model != null){
            EObject element = null;
            Iterator<EObject> it = model.eAllContents();
            while(it.hasNext()) {
                EObject current = it.next();
                if(current.eResource().getURIFragment(current).equals(tp.getPositionID())) {
                    element = current;
                    break;
                }
            }
            // TODO stuck here
        }
    }


My first opinion was to obtain the corresponding ModelElementItem, create a StructuredSelection and set the selection.

If I understand it right the method ModelExplorerPageBookView.findElementForEObject(TreeViewer treeViewer, EObject eObjectToFind) should give me the ModelElementItem.

I need the TreeViewer to use this method and to set the selection.

But I can't obtain the TreeViewer. There are access restriction while doing this:

((ModelExplorerPage)modelExplorerPageBookView.getCurrentPage()).getViewer()


I tried a lot of other things without success.

Am I on the right way? If yes, how to proceed? If no, which is the best way to implement such use case?

Best regards,
guersoy

I solved it. Here is the complete code:

    public void showTracePoint(TracePoint tp) throws TracingException {
        // create editor input
        FileEditorInput fileEditorInput = createFileEditorInput(tp.getResourceID());
        // open editor
        try {
            PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage()
                    .openEditor(fileEditorInput,EDITOR_ID);
        } catch (PartInitException e) {
            throw new TracingException("Could not open model editor.", e);
        }
        // open explorer
        ModelExplorerPageBookView modelExplorerPageBookView = null;
        try {
            modelExplorerPageBookView = (ModelExplorerPageBookView) PlatformUI
                    .getWorkbench().getActiveWorkbenchWindow().getActivePage()
                    .showView(EXPLORER_ID);
        } catch (PartInitException e) {
            throw new TracingException("Could not open model explorer.", e);
        }
        // obtain model element
        EObject model = null;
        try {
            model = UmlUtils.getUmlModel().lookupRoot();
        } catch (NotFoundException e) {
            throw new TracingException("Could not obtain model root.", e);
        }
        if (model != null){
            EObject element = null;
            Iterator<EObject> it = model.eAllContents();
            while(it.hasNext()) {
                EObject current = it.next();
                if(current.eResource().getURIFragment(current).equals(tp.getPositionID())) {
                    element = current;
                    break;
                }
            }
            if (element == null)
                throw new TracingException("Element does not exist.");
            // select in view
            IPage page = modelExplorerPageBookView.getCurrentPage();
            IViewPart viewPart = (IViewPart) ((IAdaptable) page).getAdapter(IViewPart.class);
            if (viewPart instanceof ModelExplorerView) {
                ModelExplorerView modelExplorerView =  (ModelExplorerView) viewPart;
                if (element != null) {
                    CommonViewer treeViewer = modelExplorerView.getCommonViewer();
                    Object modelElementItem = modelExplorerPageBookView.findElementForEObject (treeViewer, element);
                    if (modelElementItem != null) {
                        TreePath treePath = new TreePath(new Object[] {
                                modelElementItem
                        });
                        EObject parent = element.eContainer();
                        if (parent != null) {
                            Object parentElement = modelExplorerPageBookView.findElementForEObject (treeViewer, parent);
                            treeViewer.expandToLevel(parentElement, 1);
                        }
                        treeViewer.setSelection(new TreeSelection (treePath), true);
                    }
                }
            }
        }
    }
