Member Function Documentation

CreateProcessingThread()

void vtkSlicerApplicationLogic::CreateProcessingThread

(

)

Create a thread for processing.

GetClassName()

virtual const char * vtkSlicerApplicationLogic::GetClassName ( )

virtual

Reimplemented from vtkMRMLApplicationLogic.

GetModuleShareDirectory()

static std::string vtkSlicerApplicationLogic::GetModuleShareDirectory ( const std::string & moduleName, const std::string & filePath )

static

Get share directory associated with moduleName located in filePath.

GetModuleSlicerXYLibDirectory()

static std::string vtkSlicerApplicationLogic::GetModuleSlicerXYLibDirectory ( const std::string & filePath )

static

Get Slicer-X.Y lib directory associated with module located in filePath.

GetModuleSlicerXYShareDirectory()

static std::string vtkSlicerApplicationLogic::GetModuleSlicerXYShareDirectory ( const std::string & filePath )

static

Get Slicer-X.Y share directory associated with module located in filePath.

GetReadDataQueueSize()

unsigned int vtkSlicerApplicationLogic::GetReadDataQueueSize

(

)

Return the number of items that need to be read from the queue (this allows code that invokes command line modules to know when multiple items are being returned and have all been returned).

GetUserInformation()

vtkPersonInformation * vtkSlicerApplicationLogic::GetUserInformation

(

)

Get information about the current user (name, login, email, organization, etc.) Values are allowed to be modified.

GetViewDisplayableManagerByClassName()

vtkMRMLAbstractDisplayableManager * vtkSlicerApplicationLogic::GetViewDisplayableManagerByClassName	(	vtkMRMLAbstractViewNode *	viewNode,
		const char *	className ) const

Get view displayable manager given its class name.

This provides a Qt-independent way to access displayable managers, by looking up the vtkMRMLDisplayableManagerGroup associated with a vtkMRMLViewNode (3D) or vtkMRMLSliceNode (2D).

Parameters

viewNode	MRML view node (slice or 3D) whose displayable manager group will be queried.
className	Class name of the displayable manager (e.g., "vtkMRMLCameraDisplayableManager").

Returns

The displayable manager instance if found, otherwise nullptr. The returned pointer is owned by the displayable manager group and must not be deleted by the caller.

This API is primarily intended for accessing low-level VTK actors or widgets without going through Qt view classes, and is especially useful in headless contexts or alternative frontends (e.g., trame).

IsA()

virtual int vtkSlicerApplicationLogic::IsA ( const char * type )

virtual

Reimplemented from vtkMRMLApplicationLogic.

IsEmbeddedModule()

static bool vtkSlicerApplicationLogic::IsEmbeddedModule ( const std::string & filePath, const std::string & applicationHomeDir, const std::string & slicerRevision )

static

Return True if filePath is a descendant of applicationHomeDir.

Note

On macOS extensions are installed in the "<Slicer_EXTENSIONS_DIRBASENAME>-<slicerRevision>" folder being a sub directory of the application dir, an extra test is performed to make sure the tested filePath doesn't belong to that "<Slicer_EXTENSIONS_DIRBASENAME>-<slicerRevision>" folder. If this is the case, False will be returned.

IsPluginBuiltIn()

static bool vtkSlicerApplicationLogic::IsPluginBuiltIn ( const std::string & filePath, const std::string & applicationHomeDir, const std::string & slicerRevision )

static

Return true if the plugin identified with its filePath is a built-in Slicer module.

IsPluginInstalled()

static bool vtkSlicerApplicationLogic::IsPluginInstalled ( const std::string & filePath, const std::string & applicationHomeDir )

static

Return true if the plugin identified with its filePath is loaded from an install tree.

Warning

Since internally the function looks for the existence of CMakeCache.txt, it will return an incorrect result if the plugin is installed in the build tree of an other project.

IsTypeOf()

static int vtkSlicerApplicationLogic::IsTypeOf ( const char * type )

static

ProcessReadSceneData()

void vtkSlicerApplicationLogic::ProcessReadSceneData ( ReadDataRequest & req )

protected

Process a request to read data into a scene. This method is called by ProcessReadData() in the application main thread because calls to load data will cause a Modified() on a node which can force a render.

ProcessWriteData()

void vtkSlicerApplicationLogic::ProcessWriteData

(

)

Process a request to write data from a referenced node.

ProcessWriteSceneData()

void vtkSlicerApplicationLogic::ProcessWriteSceneData ( WriteDataRequest & req )

RequestModified()

vtkMTimeType vtkSlicerApplicationLogic::RequestModified

(

vtkObject *

)

Request a Modified call on an object. This method allows a processing thread to request a Modified call on an object to be performed in the main thread. This allows the call to Modified to trigger GUI changes. RequestModified() is called from the processing thread to modify an object in the main thread. Return the request UID (monotonically increasing) of the request or 0 if the request failed to be registered.

Todo

Fire RequestProcessedEvent when processing Modified requests.

RequestReadData(), RequestWriteData()

RequestModifiedCallback()

static void vtkSlicerApplicationLogic::RequestModifiedCallback ( vtkObject * caller, unsigned long eid, void * clientData, void * callData )

static

Callback function to request invoking a modified event on the main thread. This function may be called from any thread.

RequestReadFile()

vtkMTimeType vtkSlicerApplicationLogic::RequestReadFile	(	const char *	refNode,
		const char *	filename,
		int	displayData = false,
		int	deleteFile = false )

Request that data be read from a file and set it on the referenced node. The request will be sent to the main thread which will be responsible for reading the data, setting it on the referenced node, and updating the display. Return the request UID (monotonically increasing) of the request or 0 if the request failed to be registered. When the request is processed, RequestProcessedEvent is invoked with the request UID as calldata.

RequestReadScene()

vtkMTimeType vtkSlicerApplicationLogic::RequestReadScene	(	const std::string &	filename,
		std::vector< std::string > &	targetIDs,
		std::vector< std::string > &	sourceIDs,
		int	displayData = false,
		int	deleteFile = false )

Request that a scene be read from a file. Mappings of node IDs in the file (sourceIDs) to node IDs in the main scene (targetIDs) can be specified. Only nodes listed in sourceIDs are loaded back into the main scene. Hierarchical nodes will be handled specially, in that only the top node needs to be listed in the sourceIds. Return the request UID (monotonically increasing) of the request or 0 if the request failed to be registered. When the request is processed, RequestProcessedEvent is invoked with the request UID as calldata.
