Return value

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

Flags

Long name (short name)	Argument types	Properties
-activeTab(-at)	int

-addNewNodes(-ann)	boolean
New nodes should be added to the graph, default is on.
-addNode(-an)	string
Adds a specified node to the graph. Passing an empty string means the current model selection will be added to the graph.
-additiveGraphingMode(-agm)	boolean
When enabled, the graphing will add node networks to the existing graph instead of replacing it.
-allAttributes(-ala)	boolean
Attributes should not be filtered out of the graph, default is off.
-allNodes(-aln)	boolean
Nodes should not be filtered out of the graph, default is off.
-allowNewTabs(-ant)
Query only. Returns whether this Node Editor is allowed to have new tabs added, either by creating a new tab or duplicating an existing one.
-allowTabTearoff(-att)	boolean
Control whether or not the tabs can be torn off and floated. Defaults to true.
-autoSizeNodes(-asn)	boolean
When enabled, default node widths will be dynamically determined by the node name length, default is on.
-beginCreateNode(-bcn)
Begin interactive node-creation at the mouse position. This will create a control which allows quick creation of a node in the editor. The actual creation is delegated to the createNodeCommand.
-beginNewConnection(-bnc)	string
Begin a new interactive connection at the given attribute.
-breakSelectedConnections(-bsc)
Break the selected attribute connections.
-closeAllTabs(-cat)
Close all tabs on the tab widget.
-closeTab(-clt)	int

-connectSelectedNodes(-csn)
Creates a connection between all selected nodes in the editor. The default output port of one node is connected to the default input port of the next node in the selection order.
-connectionMinSegment(-csm)	float
Sets the minimum segment length ratio of the connection leaving an output port. Applies to "straight", "corner" and "s-shape" connection styles. Value must be between 0.0 and 1.0.

-connectionRoundness(-csr)	float
Sets the roundness factor for each connection edges. Applies only to "s-shape" connection style. Value must be between 0.5 and 1.0.
-connectionStyle(-cs)	string
Sets how the connection between nodes are drawn. Mode values are: "bezier", "straight", "corner" and "s-shape". In query mode, returns current connection style.

When enabled, the size of the node name will consistently match the current zoom level. When disabled, the node name size will remain the same after zooming out past a certain level. Default is on.
-contentsChangedCommand(-cc)	script
Specifies a function to be called whenever the contents of the node editor changes.
-control(-ctl)
Query only. Returns the top level control for this editor. Usually used for getting a parent to attach popup menus. Caution: It is possible for an editor to exist without a control. The query will return "NONE" if no control is present.
-createInfo(-ci)	string
Creates or modifies a hyperGraphInfo network to save the state of the editor.
-createNodeCommand(-cnc)	script
Specifies a function to be used to create nodes through the editor. The function will be passed the name of the chosen node type. This is used by the tab-create workflow. By default createNode is used.
-createTab(-ct)	int [ string ]

You can optionally (Python only) specify a tab label, otherwise it will be set with a default name. In Mel using an empty string ("") for the tab label will set it with a default name. The new tab becomes the current (active) tab. Note: Only certain Node Editors are allowed to create new tabs, which can be checked by using the -allowNewTabs flag.

If another node is selected the edit mode will end automatically. To end the edit mode use an empty string for node. Takes an optional edit mode command which accepts: "hideall" (sets all the attributes to hidden), "showall" (sets all the attributes to visible), "preview" (temporarily shows only the visible attributes), "revert" (restores the visibility settings of the attributes to what they were before edit mode) and "reset" (the visible attributes are reset so that only the interesting attributes are displayed). In query mode returns the name of the node, if any, in edit mode. Note: the optional string argument is ignored in query mode.
-cycleHUD(-ch)
Change the HUD to the next state.
-defaultPinnedState(-dps)	boolean
Sets default pinned state of all nodes, 1 for pinned, 0 for unpinned. default value 0
-defineTemplate(-dt)	string

If "-" is supplied, the data is returned as a string, otherwise the size in bytes of the written file is returned. In edit mode: Sets the positions of nodes in the graph from a Graphviz output file in plain format. Only the node position, width and height information is used. If the argument starts with "graph ", it will be treated as the plain data instead of a filename. In query mode, this flag needs a value.
-downstream(-ds)

-duplicateTab(-dpt)	int [ int ]
Duplicates the tab at the specified index, placing it at the second optional (Python only) specified index. To place duplicated tab at the end use -1. The duplicated tab becomes the current (active) tab. Note: Only certain Node Editors are allowed to duplicate tabs, which can be checked by using the -allowNewTabs flag.
-enableOpenGL(-egl)	boolean
