hi all,
i'm trying to monitor user deletions. using
OpenMaya.MNodeMessage.addNodeAboutToDeleteCallback()
I'm trying to protect afew nodes from deletion, if somthing down the
line in a chain is selected for deletion.
problem is because maya deletes from child to selected node i can never
get to say unparent the children so they dont delete. and then allow
maya to run its course and delete only selected nodes.
is there a way of muting or destorying a deletion callback before it
happens? it seems maya is commited once cmds.delete() or "doDelete;" is
called. even if i say try to lockNode or anything like that.
i though i might be able to use
OpenMaya.MCommandMessage.addCommandCallback("delete", myfunction()) but
it seems to bug out for me. so i cant test this option. just get alot of
warning. anyone used this option before.
i want to try some changes befor maya commits to deleting nodes.
not sure what my option might be here. can i perhaps undo on say a
MDGModifier or something?
i guess the only other option which id rather not do it to overwrite the
"doDelete;" mel function but then that dosent account for cmds.delete().
anyway insights would be great.
john
