super(part);
// TODO Auto-generated constructor stub
}

if (clipboard == null) {
return null;
}
return clipboard;
}

protected void init() {
setId(ActionFactory.COPY.getId());
setText("Copy");
setToolTipText("Copy");
ISharedImages sharedImages =
PlatformUI.getWorkbench().getSharedImages();
setImageDescriptor(sharedImages.getImageDescriptor(
ISharedImages.IMG_TOOL_COPY));
setDisabledImageDescriptor(sharedImages.

ISharedImages.IMG_TOOL_COPY_DISABLED));

getClipboard().setContents(selectionList);
}

/* (non-Javadoc)

You can find working Copy and Paste code in the GMT/UMLX evolution of EDiagram,
but ... there the selection is consistently in model objects not EditParts
so that non-GEF selections can join in. See org.eclipse.gmt.umlx.editor.actions.CopyAction etc.
