for a tree of nodes, I'd like to select not only a node but also its
outbound connections and their endpoint nodes, and so on. Obviously
need to detect cycles. I have found no example of this. Any ideas?
Thanks

List<?> objectToCycle = new ArrayList<?>;
List<ShapeNodeEditPart> editParts = (List<ShapeNodeEditPart>) diagramEditPart.getChildren();
editorPart = (DiagramDocumentEditor) PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().getActiveEditor();
diagramWorkbenchPart = (IDiagramWorkbenchPart) editorPart;
for (ShapeNodeEditPart part : editParts) {
if(((View) part.getModel()).getElement() == objectToCycle ){
diagramWorkbenchPart.getDiagramGraphicalViewer().appendSelection(part);
}
}
HTH, bye
Giovanni
