lockNode([ignoreComponents=boolean],
[lock=boolean], [lockName=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Containers may also be set to lock unpublished attributes.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this state, unpublished member attributes may not have existing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unlock all unpublished attributes on the members of the container.
For non-containers, lock or unlock unpublished attributes on the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. |
|
lockName(ln)
 |
boolean |
|
|
Specifies the new lock state for the node's name. |
