pymel.core.windows.nodeEditor¶

nodeEditor(*args, **kwargs)¶

This command creates/edits/queries a nodeEditor editor. The optional argument is the name of the control.

Flags:

Long Name / Short Name		Argument Types	Properties
activeTab / at		int
	Gets/sets the index of the tab widget’s (active) visible tab. Note: the index is zero-based.
addNewNodes / ann		bool
	New nodes should be added to the graph, default is on.
addNode / an		unicode
	Adds a specified node to the graph. Passing an empty string means the current model selection will be added to the graph.
additiveGraphingMode / agm		bool
	When enabled, the graphing will add node networks to the existing graph instead of replacing it.
allAttributes / ala		bool
	Attributes should not be filtered out of the graph, default is off.
allNodes / aln		bool
	Nodes should not be filtered out of the graph, default is off.
allowNewTabs / ant		bool
	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		bool
	Control whether or not the tabs can be torn off and floated. Defaults to true.
autoSizeNodes / asn		bool
	When enabled, default node widths will be dynamically determined by the node name length, default is on.
backToParentView / bpv		bool
beginCreateNode / bcn		bool
	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		unicode
	Begin a new interactive connection at the given attribute.
breakSelectedConnections / bsc		bool
	Break the selected attribute connections.
closeAllTabs / cat		bool
	Close all tabs on the tab widget.
closeTab / clt		int
	Closes the tab on the tab widget at the specified index. Note: using this flag on a torn-off tab will close the node editor since there can be only a single tab. In this case the index argument is ignored.
connectNodeOnCreation / cno		bool
connectOnDrop / cod		bool
connectSelectedNodes / csn		bool
	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.

contentsChangedCommand / cc		script
	Specifies a function to be called whenever the contents of the node editor changes.
control / ctl		bool
	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 NONEif no control is present.

	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 createNodeis used.
createTab / ct		int, unicode
	Create a new tab inserting it into the tab widget at the specified index. If index is out of range (such as -1), the tab is simply appended. 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.
