Hi guys,

I need the method that pass me the element with an click event in the diagram. I cannot find it in the source code of Papyrus. Anyone an idea?

What is quite often used in Papyrus is a context menu entry that performs an action with the currently selected element. The class EMFHelper (in oep.infra.emf.utils) is used to convert a selection either in the model explorer or in a diagram to an EObject. The selection itself can be obtained via the selection service, see below.

Ansgar

IStructuredSelection selection = (IStructuredSelection) PlatformUI.getWorkbench().getActiveWorkbenchWindow().getSelectionService().getSelection();

if (selection != null) {
    selectedEObject = EMFHelper.getEObject(selection.getFirstElement());
}
