using callbacks to stop a node from being deleted

[suck]

this is way hacky, but you could force an undo.

[f97ao]

fn FW_ToolsUndoDelete theNode=
(

if theNode==FW_MotherObject and FW_DetailMode then
(
qDelete=queryBox "Are you sure you want to delete the Detail Area?\nThis cannot be undone." title:"PolySpeed Warning"
--qDelete=false
if not(qDelete) then
(
newNode=FW_ToolsTrueCopy theNode
FW_MotherObject=newNode
)
else
callbacks.removeScripts id:#DetailDeleteProtection

)


FW_UpdateRunning #on
)

fn FW_ToolsTrueCopy theNode =
(
--theNode =$
if IsValidNode theNode do
(
startName=theNode.name
startWireColor=theNode.wirecolor

theNode.name+="_copyTemp"
newNode=copy theNode

newNode.name=startName
newNode.wirecolor=startWirecolor
select newNode
newNode
)
)


This is cut and pasted from PolySpeed. This is the way I make sure that the user don't delete stuff they shouldn't delete. Basically I just copy the object and transfer the name and wirecolor to it.

Hope that helps.

Thanks Andreas, that works great! I just needed to add a getUserProp and setUserProp in the copy function to retain some extra data, but that was it.

Glad it worked. If you find any better ways of doing it please tell. I just added it so haven't tested it that much. It seems to work fine though.
