◆ StateType

enum vtkMRMLScene::StateType

The state of the scene reflects what the scene is doing. The scene is in BatchProcessState when nodes are either inserted or removed contiguously. The methods Connect, Import and Clear automatically set the scene in specific states. It is possible to manually set the scene in a specific state using StartState() and EndState(). When the scene is in BatchProcessState mode, observers can ignore the events NodeAddedEvent and NodeRemovedEvent to only synchronize with the scene when the scene is no longer in BatchProcessState (EndBatchProcessEvent being fired).

The call scene->Connect("myScene.mrml"); that closes and import a scene will fire the events:

Member Function Documentation

◆ AddDefaultNode()

void vtkMRMLScene::AddDefaultNode ( vtkMRMLNode * node )

Set a default node for node creation and reset. One default node can be specified for each node class. It is useful for overriding default values that are set in a node's constructor.

◆ AddNewNodeByClass()

vtkMRMLNode* vtkMRMLScene::AddNewNodeByClass	(	std::string	className,
		std::string	nodeBaseName = `""`
	)

Instantiate and add a node to the scene.

This is the preferred way to create and add a new node to the scene. It ensures that the new node properties are initialized considering its default nodes.

The method calls CreateNodeByClass(), vtkMRMLNode::SetName() and AddNode().

Note: Instead of calling SetName() after creating the node, prefer passing nodeBaseName, indeed the method AddNode() ensures that the final node name is unique in the scene by appending a suffix if needed.

See also: CreateNodeByClass(), vtkMRMLNode::SetName(), AddNode(); AddDefaultNode(); GenerateUniqueName()

◆ AddNode()

vtkMRMLNode* vtkMRMLScene::AddNode ( vtkMRMLNode * nodeToAdd )

Add a node to the scene and send vtkMRMLScene::NodeAboutToBeAddedEvent, vtkMRMLScene::NodeAddedEvent and vtkMRMLScene::SceneModified events.

A unique ID (e.g. "vtkMRMLModeNode1", "vtkMRMLScalarVolumeNode4") is generated and set to the node. If the node has no name (i.e. vtkMRMLNode::GetName() == 0), a unique name is given to the node (e.g. "Model" if it's the first model node added into the scene, "Model_1" if it's the second, etc. If node is a singleton, and a node of the same class with the same singleton tag already exists in the scene, nodeToAdd is NOT added but its properties are copied (c.f. vtkMRMLNode::CopyWithScene()) into the already existing singleton node. That node is then returned.

◆ AddNodeID()

void vtkMRMLScene::AddNodeID ( vtkMRMLNode * node )

protected

Add node to NodeIDs map used to speedup GetByID() method.

◆ AddNodeNoNotify()

vtkMRMLNode* vtkMRMLScene::AddNodeNoNotify ( vtkMRMLNode * n )

protected

Add a node to the scene without invoking a vtkMRMLScene::NodeAddedEvent event.

Warning: Use with extreme caution as it might unsynchronize observer.

◆ AddReferencedNodeID()

void vtkMRMLScene::AddReferencedNodeID	(	const char *	id,
		vtkMRMLNode *	refrencingNode
	)

The Scene maintains a map (NodeReferences) to keep track of the relationship between node IDs and the nodes referencing those IDs. Each node can use the call AddReferencedNodeID() to tell the scene that is 'has an interest' in the given ID so that the scene can notify that node when the ID has been remapped. It does this notification through the UpdateNodeReferences() call.

◆ AddReferencedNodes()

void vtkMRMLScene::AddReferencedNodes	(	vtkMRMLNode *	node,
		vtkCollection *	refNodes,
		bool	recursive = `true`
	)

protected

Get referenced nodes

Parameters

recursive All referenced nodes recursively if true, only directly referenced nodes if false. Default is true.

◆ AddReservedID()

void vtkMRMLScene::AddReservedID ( const char * id )

◆ AddURIHandler()

void vtkMRMLScene::AddURIHandler ( vtkURIHandler * handler )

Add a uri handler to the collection.

◆ BuildID()

std::string vtkMRMLScene::BuildID	(	const std::string &	baseID,
		int	idIndex
	)		const

protected

◆ BuildName()

std::string vtkMRMLScene::BuildName	(	const std::string &	baseName,
		int	nameIndex
	)		const

protected

Combine a basename and an index to produce a full name.

◆ Clear()

void vtkMRMLScene::Clear ( int removeSingletons = 0 )

Remove nodes and clear undo/redo stacks.

Parameters

removeSingletons If set to true then it removes all singleton nodes (interaction, color, view nodes etc.) from the scene. If it is set to false then it just resets singleton nodes to their default state.

◆ ClearNodeIDs()

void vtkMRMLScene::ClearNodeIDs ( )

protected

Clear NodeIDs map used to speedup GetByID() method.

◆ ClearRedoStack()

void vtkMRMLScene::ClearRedoStack ( )

clear Redo stack, delete redo history

◆ ClearUndoStack()

void vtkMRMLScene::ClearUndoStack ( )

clear Undo stack, delete undo history

◆ Commit()

int vtkMRMLScene::Commit ( const char * url = NULL )

Save scene into URL Returns nonzero on success

◆ Connect()

int vtkMRMLScene::Connect ( )

Create new scene from URL.

Returns nonzero on success.

◆ CopyDefaultNodesToScene()

void vtkMRMLScene::CopyDefaultNodesToScene ( vtkMRMLScene * scene )

Copies all default nodes into the parameter scene. Does not remove existing default nodes.

◆ CopyNode()

vtkMRMLNode* vtkMRMLScene::CopyNode ( vtkMRMLNode * n )

Add a copy of a node to the scene.

◆ CopyNodeChangedIDs()

void vtkMRMLScene::CopyNodeChangedIDs ( vtkMRMLScene * scene )

◆ CopyNodeInRedoStack()

void vtkMRMLScene::CopyNodeInRedoStack ( vtkMRMLNode * node )

protected

◆ CopyNodeInUndoStack()

void vtkMRMLScene::CopyNodeInUndoStack ( vtkMRMLNode * node )

protected

◆ CopyNodeReferences()

void vtkMRMLScene::CopyNodeReferences ( vtkMRMLScene * scene )

◆ CopyRegisteredNodesToScene()

void vtkMRMLScene::CopyRegisteredNodesToScene ( vtkMRMLScene * scene )

Copies all registered nodes into the parameter scene.

◆ CopySingletonNodesToScene()

void vtkMRMLScene::CopySingletonNodesToScene ( vtkMRMLScene * scene )

Copies all singleton nodes into the parameter scene.

◆ CreateNodeByClass()

vtkMRMLNode* vtkMRMLScene::CreateNodeByClass ( const char * className )

Create node with a given class.

Result of this method may be different than creating a node directly (using its own constructor), as this method ensures the new node properties are initialized based on the associated default node. Default node may be specified in the scene, using AddDefaultNode() method.

Note: A default node is associated with an other node if it belongs to the class hierarchy of that node.

Warning: This method does NOT add the new node to the scene. To create a new node and add it to the scene in one step, use AddNewNodeByClass().

See also: AddDefaultNode(), AddNewNodeByClass()

◆ EndState()

void vtkMRMLScene::EndState ( unsigned long state )

Unflag the scene as being in a state mode.

EndState() fires the state end event if the scene is no longer in the state mode. A matching StartState(state) must be called prior. e.g. vtkMRMLScene::EndImportEvent if state is ImportState .

EndState() internally pops the state out of the stack.

◆ FindNodeReference()

NodeReferencesType::iterator vtkMRMLScene::FindNodeReference	(	const char *	referencedId,
		vtkMRMLNode *	referencingNode
	)

protected

Get a NodeReferences iterator for a node reference.

◆ FindURIHandler()

vtkURIHandler* vtkMRMLScene::FindURIHandler ( const char * URI )

Find a URI handler in the collection that can work on the passed URI.

Returns NULL on failure

◆ FindURIHandlerByName()

vtkURIHandler* vtkMRMLScene::FindURIHandlerByName ( const char * name )

Returns a URIhandler of a specific type if its name is known.

◆ GenerateUniqueID() [1/2]

std::string vtkMRMLScene::GenerateUniqueID ( vtkMRMLNode * node )

protected

◆ GenerateUniqueID() [2/2]

std::string vtkMRMLScene::GenerateUniqueID ( const std::string & baseID )

protected

◆ GenerateUniqueName() [1/2]

std::string vtkMRMLScene::GenerateUniqueName ( const std::string & baseName )

Generate a node name that is unique in the scene. Calling this function successively with the same baseName returns a different name: e.g. baseName1, baseName2, baseName3.

◆ GenerateUniqueName() [2/2]

std::string vtkMRMLScene::GenerateUniqueName ( vtkMRMLNode * node )

protected

Return a unique name for a MRML node. It uses the node tag as the base.

		bool	exactNameMatch = `true`
	)

Return the first node in the scene that matches the filtering criteria if specified.

By default, byName will be compared using an exact match. If exactNameMatch is set to false, the node will be returned if its name starts with byName. If the pointer byHideFromEditors is not set, the function will return both the nodes hidden from editors as well as the nodes visible in editors. If the pointer byHideFromEditors is set, the function will only return the nodes that are either hidden from editors or the nodes that are visible in editors.

The problem is that it changes the node collection's internal iterator, which may cause unintended side effects in caller functions that also use the node collection's internal iterator. Use other methods instead (GetNodes(), GetNodesByClass(), etc.) or traverse collection returned by GetNodes() using a collection iterator.

◆ RegisterNodeClass() [1/2]

void vtkMRMLScene::RegisterNodeClass	(	vtkMRMLNode *	node,
		const char *	tagName
	)

Register a node class to the scene so that the scene can later create the same node type from a tag or a class name.

This is mainly used during scene loading. The XML element names are used to instantiate the nodes.

node is an instance of the class to instantiate when CreateNodeByClass() is called with a corresponding className retrieved using GetClassNameByTag(). tagName can be 0 or an XML tag a custom tagName. If tagName is 0 (default), the node GetNodeTagName() is used. Otherwise, tagName is used.

The signature with tagName != 0 is useful to add support for scene backward compatibility. Calls with an obsolete tag should be wrapped with: #if MRML_SUPPORT_VERSION < 0x0X0Y0Z and #endif where X is the major version of Slicer scene to support, Y the minor and Z the patch version.

◆ StartState()

void vtkMRMLScene::StartState	(	unsigned long	state,
		int	anticipatedMaxProgress = `0`
	)

Flag the scene as being in a state mode.

A matching EndState(state) must be called later. Nested states are supported as long as they all have their own EndState() calls. StartState() fires the state start event if it isn't already in that state, e.g. StartImportEvent if state is ImportState . If the state is BatchProcessState , CloseState , ImportState or RestoreState and if the scene is not already in a BatchProcessState state, it also fires the event StartBatchProcessEvent .

Example:

scene->StartState(vtkMRMLScene::ImportState);
// fires: StartBatchProcessEvent, StartImportEvent
scene->StartState(vtkMRMLScene::ImportState);
// doesn't fire anything
scene->StartState(vtkMRMLScene::RestoreState);
// fires: StartRestoreEvent
scene->EndState(vtkMRMLScene::RestoreState);
// fires: EndRestoreEvent
scene->EndState(vtkMRMLScene::ImportState);
// doesn't fire anything
scene->EndState(vtkMRMLScene::ImportState);
// fires: EndImportEvent, StartBatchProcessEvent

StartState() internally pushes the state into a stack.
