additionalResourceNameChecks()

bool KisTagFilterResourceProxyModel::additionalResourceNameChecks ( const QModelIndex & index, const KisResourceSearchBoxFilter * filter ) const

virtual

additionalResourceNameChecks Some resources, like fonts, have multiple names that need to be tested. Implementers should override this function if they want additional checks on the name.

Parameters

resource	the resource index to test, this is provided by the model while testing each row.
filter,this	is the class that handles tokenisation, also provided by the model.

Returns

should return whether the current resource should be accepted by the given filter.

Reimplemented in FontFamilyTagFilterModel.

addResource()

bool KisTagFilterResourceProxyModel::addResource ( KoResourceSP resource, const QString & storageId = QString() )

overridevirtual

addResource adds the given resource to the database and storage. If the resource already exists in the given storage with md5, filename or name, the existing resource will be updated instead. If the existing resource was inactive, it will be active (undeleted).

Parameters

resource	the resource itself
storageId	the id of the storage (could be "memory" for temporary resources, the document's storage id for document storages or empty to save to the default resources folder

Returns

true if adding the resource succeeded.

Implements KisAbstractResourceModel.

exportResource()

bool KisTagFilterResourceProxyModel::exportResource ( KoResourceSP resource, QIODevice * device )

overridevirtual

exportResource exports a resource into a QIODevice

Exporting a resource as a binary blob is the only way to guarantee that its MD5 checksum is kept persistent. The underlying storage will just copy bytes into the device without doing any conversions

Parameters

resource	the resource to be exported
device	device where the resource should be written to

Returns

true if export operation has been successful

importResource()

KoResourceSP KisTagFilterResourceProxyModel::importResource ( const QString & filename, QIODevice * device, const bool allowOverwrite, const QString & storageId = QString() )

overridevirtual

importResource imports a resource from a QIODevice

Importing a resource from a binary blob is the only way to guarantee that its MD5 checksum is kept persistent. The underlying storage will just copy bytes into its location.

Parameters

filename	file name of the resource if preset. File name may be used for addressing the resource, so it is usually preferred to preserve it.
device	device where the resource should be read from

Returns

the loaded resource object
