c4d.modules.graphview.GvNode¶

class c4d.modules.graphview.GvNode¶: Use GvNodeMaster.CreateNode() to create nodes.

The GvNode is a double BaseList2D node.

Warning

This type cannot be instantiated.

Note

Please use GvNode.GetOperatorContainer() to access most parameters.

A GvNode is a node which is stored in a GvNodeMaster.

A node contains ports represented by GvPort.

Checks if the node is a group node.

Return type: bool
Parameters: mask – True if the node is a group node, otherwise False.

GvNode.SetPortType(self, port, id)¶

Changes the type of a port of this node.

Parameters

port (c4d.modules.graphview.GvPort) – A port of this node.
id (int) – The new port ID.

GvNode.ResetPortType(self, id)¶

Changes the type of the port. Used to manage dynamic data ports.

Parameters: id (int) – The type.

GvNode.RemoveUnusedPorts(self, message=True)¶

Removes all unused ports - Sends a message to the node.

Parameters: message (bool) – If this is True, the operator receives a message when the ports are removed.

GvNode.RemoveConnections(self)¶: Removes all connections of the node.

GvNode.RemovePort(self, port, message=False)¶

Removes a port from this node.

Parameters

port (c4d.modules.graphview.GvPort) – A port of this node to remove.
message (bool) – If this is True the operator receives a message when the port is removed.

GvNode.RemovePortIsOK(self, port)¶

Checks if it is OK to remove a port from this node.

Note

Used to check if a call to GvNode.RemovePort() would succeed.

Parameters: port (c4d.modules.graphview.GvPort) – A port of this node to remove.
Return type: bool
Returns: True if this port can be remove.

GvNode.GetPort(self, sub_id)¶

Retrieves a port by sub ID.

Parameters: sub_id (int) – Port sub ID.
Return type: c4d.modules.graphview.GvPort
Returns: The retrieved port, or None.

GvNode.GetPortIndex(self, id)¶

Gets the index of a port by sub ID.

Parameters: id (int) – Port sub ID.
Return type: int
Returns: Port index.

GvNode.GetOutPorts(self, type=- 1)¶

Retrieves all outports of a node.

Parameters

type (int) –

If type is set, just the ports with the given type will be returned.

Each port has its own type ID’s for the ports so check the C-header files of the node.

Return type

list of GvPort

Returns

The GvPorts or None if no port was found.

GvNode.GetInPorts(self, type=- 1)¶

Retrieves all inports of a node.

Parameters

type (int) –

If type is set, just the ports with the given type will be returned.

Each port has its own type ID’s for the ports so check the C-header files of the node.

Return type

list of GvPort

Returns

The GvPorts or None if no port was found.

GvNode.GetInPort(self, id)¶

Retrieves an inport by index.

Parameters: id (int) – the index
Return type: c4d.modules.graphview.GvPort
