|
| 1. Data object created for cut , copy or dragdrop registers every node added to it
| 2. Nodes are registered in the static multimap, mapping node to the data object it belongs to.
| 3. Node destructor checks the map and triggers cleanup for all affected data objects.
| 4. Data Object cleanup is: a) unregistering its nodes,
| b) release contained data objects
| b) entering invalid state (allowing only removal of cut objects to succeed)
| c) revoking itself from clipboard if it is on the clipboard.
| It will not do any of following: a) release references to IComponents as long as is alive
| b) prevent MMCN_CUTORMOVE to be send by invoking RemoveCutItems()
