You'll need to understand the clipsamp app and the chapter in [Concepts]
"Clipboard" , in addition:
GWNT_SELECT_STATE_CHANGE, GWNT_UNDO_STATE_CHANGE, refer to the Geoworks
Notification Type that is sent by General Change Notification lists to
objects that register with them, which is what you'll need to do to receive
and handle the messages/data that are sent out by the GCNList mechanism.
Which means you need to check out the chapter in [Concepts] about "GCN".
