Member Function Documentation

◆ addDefaultStorageNodes()

Q_INVOKABLE void qSlicerCoreIOManager::addDefaultStorageNodes ( )

Create default storage nodes for all storable nodes that are to be saved with the scene and do not have a storage node already File name is set based on node name, using use default file extension, with special characters in the node name percent-encoded. This method can be used to ensure a storage node exists before writing a storable node to file by calling storableNode->GetStorageNode()->WriteData(storableNode).

◆ allReadableFileExtensions()

Q_INVOKABLE QStringList qSlicerCoreIOManager::allReadableFileExtensions ( ) const

Return a string list of all the readable file extensions for all registered types of storage nodes. Includes the leading dot.

◆ allWritableFileExtensions()

Q_INVOKABLE QStringList qSlicerCoreIOManager::allWritableFileExtensions ( ) const

Return a string list of all the writable file extensions for all registered types of storage nodes. Includes the leading dot.

◆ completeSlicerWritableFileNameSuffix()

Q_INVOKABLE QString qSlicerCoreIOManager::completeSlicerWritableFileNameSuffix ( vtkMRMLStorableNode node) const

Returns a full extension for this storable node that is recognised by Slicer IO. Consults the storage node for a list of known suffixes, if no match is found and the .* extension exists, return the Qt completeSuffix string. If .* is not in the complete list of known suffixes, returns an empty suffix. Always includes the leading dot.

◆ createAndAddDefaultStorageNode()

static Q_INVOKABLE vtkMRMLStorageNode* qSlicerCoreIOManager::createAndAddDefaultStorageNode ( vtkMRMLStorableNode node)
static

Create and add default storage node.

◆ defaultSceneFileType()

Q_INVOKABLE QString qSlicerCoreIOManager::defaultSceneFileType ( ) const

Defines the file format that should be offered by default when the scene is saved.

◆ emitNewFileLoaded()

Q_INVOKABLE void qSlicerCoreIOManager::emitNewFileLoaded ( const QVariantMap loadedFileParameters)

This function should be used from python scripted module willing to interface with the qSlicerCoreIOManager. It will emit the signal newFileLoaded().

newFileLoaded()

◆ fileDescriptions()

Q_INVOKABLE QStringList qSlicerCoreIOManager::fileDescriptions ( const QString &  file) const

Return the file description associated with a file Usually the description is a short text of one or two words e.g. Volume, Model, ...

◆ fileDescriptionsByType()

QStringList qSlicerCoreIOManager::fileDescriptionsByType ( const qSlicerIO::IOFileType  fileType) const

◆ fileOptions()

qSlicerIOOptions* qSlicerCoreIOManager::fileOptions ( const QString &  fileDescription) const

Return the file option associated with a file type.

◆ fileType()

Q_INVOKABLE qSlicerIO::IOFileType qSlicerCoreIOManager::fileType ( const QString &  file) const

Return the file type associated with a file.

◆ fileTypeFromDescription()

Q_INVOKABLE qSlicerIO::IOFileType qSlicerCoreIOManager::fileTypeFromDescription ( const QString &  fileDescription) const

◆ fileTypes()

Q_INVOKABLE QList<qSlicerIO::IOFileType> qSlicerCoreIOManager::fileTypes ( const QString &  file) const

◆ fileWriterDescriptions()

◆ fileWriterExtensions()

Q_INVOKABLE QStringList qSlicerCoreIOManager::fileWriterExtensions ( vtkObject *  object) const

◆ fileWriterFileType()

Q_INVOKABLE qSlicerIO::IOFileType qSlicerCoreIOManager::fileWriterFileType ( vtkObject *  object) const

Return the file type associated with an VTK object.

◆ fileWriterOptions()

qSlicerIOOptions* qSlicerCoreIOManager::fileWriterOptions ( vtkObject *  object,
const QString &  extension 
) const

◆ loadFile()

Q_INVOKABLE bool qSlicerCoreIOManager::loadFile ( const QString &  fileName)

Convenient function to load a file. All the options (e.g. filetype) are chosen by default.

◆ loadNodes() [1/2]

virtual Q_INVOKABLE bool qSlicerCoreIOManager::loadNodes ( const qSlicerIO::IOFileType fileType,
const QVariantMap parameters,
vtkCollection *  loadedNodes = 0 
)
virtual

Load a list of nodes corresponding to fileType. A given fileType corresponds to a specific reader qSlicerIO. A map of qvariant allows to specify which parameters should be passed to the reader. The function return 0 if it fails. The map associated with most of the fileType should contains either fileName (QString or QStringList) or fileNames (QStringList). More specific parameters could also be set. For example, the volume reader qSlicerVolumesIO could also be called with the following parameters: LabelMap (bool), Center (bool)

Note
Make also sure the case of parameter name is respected

Reimplemented in qSlicerIOManager.

◆ loadNodes() [2/2]

virtual bool qSlicerCoreIOManager::loadNodes ( const QList< qSlicerIO::IOProperties > &  files,
vtkCollection *  loadedNodes = 0 
)
virtual

Utility function that loads a bunch of files. The "fileType" attribute should in the parameter map for each node to load.

Reimplemented in qSlicerIOManager.

◆ loadNodesAndGetFirst()

vtkMRMLNode* qSlicerCoreIOManager::loadNodesAndGetFirst ( qSlicerIO::IOFileType  fileType,
const qSlicerIO::IOProperties parameters 
)

Load a list of node corresponding to fileType and return the first loaded node. This function is provided for convenience and is equivalent to call loadNodes with a vtkCollection parameter and retrieve the first element.

◆ loadScene()

Q_INVOKABLE bool qSlicerCoreIOManager::loadScene ( const QString &  fileName,
bool  clear = true 
)

Load/import a scene corresponding to fileName This function is provided for convenience and is equivalent to call loadNodes function with QString("SceneFile")

◆ newFileLoaded

void qSlicerCoreIOManager::newFileLoaded ( const qSlicerIO::IOProperties loadedFileParameters)
signal

This signal is emitted each time a file is loaded using loadNodes() The loadedFileParameters QVariant map contains the parameters passed to the reader and also the fileType and nodeIDs keys respectively associated with a QString and a QStringList.

See also
loadNodes(const qSlicerIO::IOFileType&, const qSlicerIO::IOProperties&, vtkCollection*)

protected

Returns the list of registered readers.

◆ readers() [2/2]

QList<qSlicerFileReader*> qSlicerCoreIOManager::readers ( const qSlicerIO::IOFileType fileType) const
protected

Returns the list of registered readers or writers associated with fileType.

◆ registerIO()

void qSlicerCoreIOManager::registerIO ( qSlicerIO io)

Register the reader/writer io Note also that the IOManager takes ownership of io

◆ saveNodes()

Q_INVOKABLE bool qSlicerCoreIOManager::saveNodes ( qSlicerIO::IOFileType  fileType,
const QVariantMap parameters 
)

Save nodes (or scene) using the registered writers. Return true on success, false otherwise. Attributes are typically: For all: QString fileName (or QStringList fileNames) For nodes: QString nodeID, bool useCompression

qSlicerNodeWriter, qSlicerIO::IOProperties, qSlicerIO::IOFileType, loadNodes()

◆ saveScene()

Q_INVOKABLE bool qSlicerCoreIOManager::saveScene ( const QString &  fileName,
QImage  screenShot 
)

Save a scene corresponding to fileName This function is provided for convenience and is equivalent to call saveNodes function with QString("SceneFile") with the fileName and screenShot set as properties.

◆ setDefaultSceneFileType

void qSlicerCoreIOManager::setDefaultSceneFileType ( QString  )
slot

Defines the file format that should be offered by default when the scene is saved. Valid options are defined in qSlicerSceneWriter (for example, "MRML Scene (.mrml)" or "Medical Reality Bundle (.mrb)").
