(* rht: "20-Apr-87 20:35")
(* Select a set of note cards or a single note card, depending on SingleCardFlg. Works by interpreting all mouse
presses until a card has been chosen (if SingleCardFlg is T) or until the Done button has been pressed
(if SingleCardFlg is NIL). If the mouse press occus within a Title bar of a notecard, add that note card to the
selected list. Otherwise, if you are pointing into a note card, call the BUTTONEVENTFN for that note card.
The Selection in Progress flag has been set, so all note card BUTTONEVENTFNs should know to ignore all presses
except those that occur on link icons. Link icon presses should simply add the desination of that link to the
selected note cards list. This function should always be called from inside of an NC.CardSelectionOperation
wrapper.)
(* * rht 8/1/84: Changed second RESETSAVE call to give NC.ClearMsg a NIL argument.)
(* * rht 1/9/85: Fixed so now prints name of selected item even it's a link.)
(* * rht 2/15/85: Now can backspace over last selection chosen. Added new arg Msg so that when we reprint the list,
we can reprint the message as well.)
(* * rht 3/23/85: Added the CheckForCancelFlg arg, which if non-nil causes Cancel to be handled differently then
Done after no selections. Namely, Cancel will return the atom CANCELLED whereas Done with no selections returns
NIL. If CheckForCancelFlg is NIL then NIL is returned in both cases.)
(* * fgh 11/14/85 Updated to handle Card and NoteFile objects.)
(* * rht 11/18/85: Fixed so able to select when InstigatingNoteFile is NIL.)
(* * fgh 12/20/85 Totally rewritten for 1.3 selection mechanism. Based on COPYINSERT now rather than on takingf
over the mouse process.)
(* * fgh 1/15/86 Added call to SPAWN.MOUSE in case this is called under the mouse process)
(* * kirk 25Apr86 Changed to use SessionIcon (NC.NoteCardsIconWindow) rather than PROMPTWINDOW if no Instigating
window is supplied.)
(* * fgh 7/5/86 Added code to put CRs into printout of selected cards in order to keep prompt window from getting
infinitely wide to accomdate the printout.)
(* * rht 10/5/86: Now allows choice of cards from remote notefile.)
(* * rht 10/18/86: Give TTY process to process that originally had it if possible.)
(* * rht & pmi 11/14/86: Now checks for valid card before testing SelectionPredicate.)
(* * pmi 12/5/86 Modified prompt messages to mention SHIFT-selection.)
(* * pmi 12/12/86: Removed obsolete ReturnLinksFlg argument.)
(* * rg 3/18/87 reworked for NC.CardSelectionOperation: added NAMED-RESETSAVE forms for Card locking.)
(* * 3/23/87: Changed to call REMOVEWINDOW instead of DETACHWINDOW before deleting the attached menu.
Also changed so that menu is attached to InstigatingWindow rather than to PromptWindow. This makes it possible for
windows to "slide down" when selection ends.)
(* * rht 3/24/87: Now calls NC.CoerceToInterestedWindow)
(* * RG 4/1/87 changed CANCELLED to DON'T)
(* * rht&rg 4/20/87: Fixed bug in Undo and bug in line width calculation for prints to prompt window.)
