Struct GraphEdit

GraphEdit is an area capable of showing various GraphNodes. It manages connection events between them.


					
			struct GraphEdit
			;

GraphEdit manages the showing of GraphNodes it contains, as well as connections and disconnections between them. Signals are sent for each of these two events. Disconnection between GraphNode slots is disabled by default. It is greatly advised to enable low-processor usage mode (see OS.lowProcessorUsageMode) when using GraphEdits.

Properties

Name	Type	Description
`rightDisconnects`[get, set]	`bool`	If `true`, enables disconnection of existing connections in the GraphEdit by dragging the right end.
`scrollOffset`[get, set]	`Vector2`	The scroll offset.
`snapDistance`[get, set]	`long`	The snapping distance in pixels.
`useSnap`[get, set]	`bool`	If `true`, enables snapping.
`zoom`[get, set]	`double`	The current zoom value.

Methods

Name	Description
`_connectionsLayerDraw`
`_graphNodeMoved`
`_graphNodeRaised`
`_guiInput`
`_scrollMoved`
`_snapToggled`
`_snapValueChanged`
`_topLayerDraw`
`_topLayerInput`
`_updateScrollOffset`
`_zoomMinus`
`_zoomPlus`
`_zoomReset`
`addValidConnectionType`	Makes possible the connection between two different slot types. The type is defined with the `GraphNode.setSlot` method.
`addValidLeftDisconnectType`	Makes possible to disconnect nodes when dragging from the slot at the left if it has the specified type.
`addValidRightDisconnectType`	Makes possible to disconnect nodes when dragging from the slot at the right if it has the specified type.
`clearConnections`	Removes all connections between nodes.
`connectNode`	Create a connection between the `from_port` slot of the `from` GraphNode and the `to_port` slot of the `to` GraphNode. If the connection already exists, no connection is created.
`disconnectNode`	Removes the connection between the `from_port` slot of the `from` GraphNode and the `to_port` slot of the `to` GraphNode. If the connection does not exist, no connection is removed.
`getConnectionList`	Returns an Array containing the list of connections. A connection consists in a structure of the form `{ from_port: 0, from: "GraphNode name 0", to_port: 1, to: "GraphNode name 1" }`.
`getScrollOfs`
`getSnap`
`getZoom`
`getZoomHbox`	Gets the `HBoxContainer` that contains the zooming and grid snap controls in the top left of the graph.
`isNodeConnected`	Returns `true` if the `from_port` slot of the `from` GraphNode is connected to the `to_port` slot of the `to` GraphNode.
`isRightDisconnectsEnabled`
`isUsingSnap`
`isValidConnectionType`	Returns whether it's possible to connect slots of the specified types.
`removeValidConnectionType`	Makes it not possible to connect between two different slot types. The type is defined with the `GraphNode.setSlot` method.
`removeValidLeftDisconnectType`	Removes the possibility to disconnect nodes when dragging from the slot at the left if it has the specified type.
`removeValidRightDisconnectType`	Removes the possibility to disconnect nodes when dragging from the slot at the right if it has the specified type.
`setConnectionActivity`	Sets the coloration of the connection between `from`'s `from_port` and `to`'s `to_port` with the color provided in the `activity` theme property.
`setRightDisconnects`
`setScrollOfs`
`setSelected`	Sets the specified `node` as the one selected.
`setSnap`
`setUseSnap`
`setZoom`
