Methods Documentation

GvNodeMaster.__init__(self, host)¶

Parameters: host (BaseList2D) – Attaches a GvNodeMaster to a BaseList2D object.

GvNodeMaster.AllocNode(self, id)¶

Allocates a node without inserting it.

Parameters: id (int) – The id. See Graph View Node Types.
Return type: c4d.modules.graphview.GvNode
Returns: The new node.

GvNodeMaster.CreateNode(self, parent, id, insert=None, x=- 1, y=- 1)¶

Creates a node and inserts it.

Parameters

parent (c4d.modules.graphview.GvNode) – Parent node, can be GetRoot().
id (int) – The id. See Graph View Node Types.
insert (Optional[c4d.modules.graphview.GvNode]) – The insertion point.
x (int) – X position
y (int) – Y position.

Return type

c4d.modules.graphview.GvNode

Returns

The created node.

GvNodeMaster.GetRoot(self)¶

Retrieves the root node.

Return type: Optional[c4d.modules.graphview.GvNode]
Returns: The root node or None.

GvNodeMaster.GetOwner(self)¶

Retrieves the owner.

Return type: c4d.BaseList2D
Returns: The owner of the GvNodeMaster

GvNodeMaster.InsertFirst(self, parent, node)¶

Inserts a node first in the node list of an Xgroup.

Note

Equivalent to GeListNode.InsertUnder(), but with additional checks that parent is a group node, and that node is removed.

Parameters

parent (c4d.modules.graphview.GvNode) – Parent node. Must be in the same node master.
node (c4d.modules.graphview.GvNode) – Node to insert.

Return type

bool

Returns

True if the node was inserted, otherwise False.

GvNodeMaster.InsertLast(self, parent, node)¶

Inserts a node last in the node list of an Xgroup.

Note

Equivalent to GeListNode.InsertUnderLast(), but with additional checks that parent is a group node, and that node is removed.

Parameters

parent (c4d.modules.graphview.GvNode) – Parent node. Must be in the same node master.
node (c4d.modules.graphview.GvNode) – Node to insert.

Return type

bool

Returns

True if the node was inserted, otherwise False.

GvNodeMaster.SetHierarchy(self, insert, node, mode=GV_INSERT_AFTER)¶

Perform a hierarchy operation. Pass the arguments as a dictionary.

Parameters

insert (c4d.modules.graphview.GvNode) – Insertion point.
node (c4d.modules.graphview.GvNode) – The node to perform the operation on.
mode (int) –
The insertion mode:

GV_INSERT_UNDER

Input port.

GV_INSERT_UNDER_LAST

Insert under as last item.

GV_INSERT_BEFORE

Insert before.

GV_INSERT_AFTER

Insert after.

GV_INSERT_NONE

Not used.

Return type

bool

Returns

True if the hierarchy was set, otherwise False.

GvNodeMaster.IsEnabled(self)¶

Checks if the node master is enabled.

Return type: c4d.modules.graphview.GvNodeMaster
Returns: True if the node master is enabled.

GvNodeMaster.GetPrefs(self)¶

Returns the settings container.

Return type: c4d.BaseContainer
Returns: A copy of the settings container.

GvNodeMaster.SetPrefs(self, bc)¶

Set the settings container.

Parameters: bc (c4d.BaseContainer) – The settings container.

GvNodeMaster.AddUndo(self)¶

Call this function if you manipulated something with a node master, and you want it to be undoable.

Return type: bool
Returns: True if successful, otherwise False.

GvNodeMaster.Execute(self, thread=None)¶

Calculates the GvNodeMaster.

Changed in version S22.
