Member Function Documentation

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.

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().

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

qSlicerIO::IOProperties, qSlicerIO::IOFileType, saveNodes()

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.

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

reader()

qSlicerFileReader* qSlicerCoreIOManager::reader ( const QString &  ioDescription ) const

protected

readers() [1/2]

const QList<qSlicerFileReader*>& qSlicerCoreIOManager::readers ( ) const

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

See also

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.

writers() [1/2]

const QList<qSlicerFileWriter*>& qSlicerCoreIOManager::writers ( ) const

protected

Returns the list of registered writers.

writers() [2/2]

QList<qSlicerFileWriter*> qSlicerCoreIOManager::writers ( const qSlicerIO::IOFileType &  fileType ) const

protected

Returns the list of registered writers for a given fileType.
