lockNode([ignoreComponents=boolean], [lock=boolean], [lockUnpublished=boolean])
Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.
lockNode is undoable, queryable, and NOT editable.
Locks or unlocks one or more dependency nodes. A locked node is restricted
in the following ways:
- It may not be deleted.
- It may not be renamed.
- Its parenting may not be changed.
- Attributes may not be added to or removed from it.
- Locked attributes may not be unlocked.
- Unlocked attributes may not be locked.
Note that an unlocked attribute of a locked node may still have its value
set, or connections to it made or broken. For more information on attribute
locking, see the setAttr command.
If no node names are specified then the current selection list is used.
There are a few special behaviors when locking containers. Containers are
automatically expanded to their constituent objects. When a container is
locked, members of the container may not be unlocked and the container
membership may not be modified. Containers may also be set to lock unpublished
attributes. When in this state, unpublished member attributes may not have
existing connections broken, new connections cannot be made, and values on unconnected
attributes may not be modified. Parenting is allowed to change on members of locked
containers that have been published as parent or child anchors.

Properties |
lock(l)
|
boolean
|
 
|
|
|
Specifies the new lock state for the node. The default is true.
|
|
ignoreComponents(ic)
|
boolean
|
|
|
|
Normally, the presence of a component in the list of objects to be locked
will cause the command to fail with an error. But if this flag is supplied
then components will be silently ignored.
|
|
lockUnpublished(lu)
|
boolean
|
|
|
|
Used in conjunction with the lock flag. On a container, lock or unlock all
unpublished attributes on the members of the container. For non-containers,
lock or unlock unpublished attributes on the specified node.

# Unlock the sphere, then it can be deleted.
