Synopsis

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:

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 Containers may also be set to lock unpublished attributes. When in this state, unpublished member attributes may not have existing connections broken, new connections cannot be made, and values on unconnected attributes may not be modified.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.

Return value

boolean[]For query execution.

In query mode, return type is based on queried flag.

Flags

ignoreComponents, lock, lockUnpublished
Long name (short name) Argument types Properties
lock(l) boolean createquery
Specifies the new lock state for the node. The default is true.
ignoreComponents(ic) boolean createquery
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 createquery
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 On a container, lock or unlock all unpublished attributes on the members of the container. For non-containers, lock or unlock unpublished attributes on the specified node.

Flag can appear in Create mode of command Flag can appear in Edit mode of command
Flag can appear in Query mode of command Flag can have multiple arguments, passed either as a tuple or a list.

Python examples

import maya.cmds as cmds

# create a sphere, lock it, then try to delete it.
cmds.sphere( n='sphere1' )
cmds.lockNode( 'sphere1' )
cmds.delete( 'sphere1' )
# Error: Cannot delete locked nodes.
# Unlock the sphere, then it can be deleted.
cmds.lockNode( 'sphere1', lock=False )
cmds.delete( 'sphere1' )
