Copy a node

GoJS
#1

Dear Sir,

I was experimenting with gojs, especially with Uml Class example, and wanted to know if there is a way to block the copy of a selected node (or what happens with ctrl + c and ctrl + v),
can you tell if exist a way to stop that?

Thanks a lot

Either set Diagram.allowCopy to false or set Part.copyable to false. Read more at GoJS User Permissions -- Northwoods Software.
