nodeOutliner( [string] , [addCommand=script], [addObject=name], [attrAlphaOrder=string], [connectivity=name], [currentSelection=boolean], [lastMenuChoice=string], [longNames=boolean], [menuCommand=script], [menuMultiOption=boolean], [multiSelect=boolean], [niceNames=boolean], [noConnectivity=boolean], [nodesDisplayed=boolean], [pressHighlightsUnconnected=boolean], [remove=string], [removeAll=boolean], [replace=name], [selectCommand=script], [showConnectedOnly=boolean], [showHidden=boolean], [showInputs=boolean], [showNonConnectable=boolean], [showNonKeyable=boolean], [showOutputs=boolean], [showPublished=boolean], [showReadOnly=boolean])

Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.

nodeOutliner is undoable, queryable, and editable.

The nodeOutliner command creates, edits and queries an outline control that shows dependency nodes and their attributes. Compound attributes are further expandable to show their children. Additional configure flags allow multi selection, customizable commands to issue upon selection, and showing connections (and connectability) to a single input attribute. There are also the abilities to add/remove/replace nodes through the command line interface, and drag/add.

In some configurations, dragging a connected attribute of a node will load the node at the other end of the connection.

There is a right mouse button menu and a flag to attach a command to it. The menu is used to list the specific connections of a connected attribute. Clicking over any spot but the row of a connected attribute will show an empty menu. By default, there is no command attached to the menu.

Return value


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


addCommand, addObject, attrAlphaOrder, connectivity, currentSelection, lastMenuChoice, longNames, menuCommand, menuMultiOption, multiSelect, niceNames, noConnectivity, nodesDisplayed, pressHighlightsUnconnected, remove, removeAll, replace, selectCommand, showConnectedOnly, showHidden, showInputs, showNonConnectable, showNonKeyable, showOutputs, showPublished, showReadOnly
Long name (short name) Argument types Properties
addCommand(ac) script createqueryedit
Command executed when the node outliner adds something. String commands use substitution of the term %node for whatever is added, eg, if you want to print the object added, the command should be "print(\"%node \\n\")". Callable python objects are passed the node name.
addObject(a) name edit
add the given object to the display
remove(rm) string editmultiuse
remove the given object from the display
removeAll(rma) boolean edit
remove all objects from the display
replace(rpl) name queryedit
replace what's displayed with the given objects
showInputs(si) boolean queryedit
show only UI visible attributes that can be connected to
showOutputs(so) boolean queryedit
show only UI visible attributes that can be connected from
showPublished(sp) boolean queryedit
Show only published attributes for an asset or a member of an asset. This flag is ignored on nodes not related to assets.
showReadOnly(sro) boolean queryedit
show only read only attributes attributes that can be connected from
showHidden(sh) boolean queryedit
show (true) or hide (false) UI invisible attributes that match the input/output criteria
showNonKeyable(snk) boolean queryedit
show (true) or hide (false) non keyframeable (animatable) attributes that match the input/output criteria
showNonConnectable(snc) boolean queryedit
show (true) or hide (false) non connectable attributes that match the input/output criteria
showConnectedOnly(sco) boolean queryedit
show (true) or hide (false) only attributes that are connected matching input/output criteria
connectivity(c) name queryedit
Takes an attribute argument ("nodeName.attributeName"), dims any attributes that can't connect to the given, and highlights any attributes already connected
noConnectivity(nc) boolean edit
Reset the node outliner to not show any connectivity, ie, redraw all rows normally.
multiSelect(ms) boolean queryedit
Allow multiSelect; more than one thing to be selected at a time
selectCommand(sc) script queryedit
Command issued by selecting. Different from the c flag in that this command will only be issued if something is selected.
currentSelection(cs) boolean query
Retruns a string array containing what is currently selected
nodesDisplayed(nd) boolean query
Returns a string array containing the list of nodes showing in the node Outliner
menuCommand(mc) script edit
Attaches the given command to each item in the popup menu.
lastMenuChoice(lmc) string query
Returns the text of the most recent menu selection.
menuMultiOption(mmo) boolean queryedit
Sets whether a menu option labelled "next available" will appear as the first option on any multi-attribute's right mouse button menu. Defaults to True.
pressHighlightsUnconnected(phu) boolean queryedit
Sets whether clicking on an unconnected plug will select it or not. Default is True.
longNames(ln) boolean queryedit
Controls whether long or short attribute names will be used in the interface. Note that this flag is ignored if the niceNames flag is set. Default is short names. Queried, returns a boolean.
niceNames(nn) boolean queryedit
Controls whether the attribute names will be displayed in a more user-friendly, readable way. When this is on, the longNames flag is ignored. When this is off, attribute names will be displayed either long or short, according to the longNames flag. Default is on. Queried, returns a boolean.
attrAlphaOrder(aao) string createqueryedit
Specify how attributes are to be sorted. Current recognised values are "default" for no sorting and "ascend" to sort attributes from 'a' to ''z' and "descend" to sort from 'z' to 'a'. Notes: a) this only applies to top level attributes.

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.
