◆ createSymbolLayer()

QgsSymbolLayer* QgsSymbolLayerMetadata::createSymbolLayer ( const QgsStringMap map)
inlineoverridevirtual

Create a symbol layer of this type given the map of properties.

Implements QgsSymbolLayerAbstractMetadata.

Definition at line 115 of file qgssymbollayerregistry.h.

◆ createSymbolLayerFromSld()

QgsSymbolLayer* QgsSymbolLayerMetadata::createSymbolLayerFromSld ( QDomElement &  )
inlineoverridevirtual

Create a symbol layer of this type given the map of properties.

Reimplemented from QgsSymbolLayerAbstractMetadata.

Definition at line 117 of file qgssymbollayerregistry.h.

◆ createSymbolLayerWidget()

QgsSymbolLayerWidget* QgsSymbolLayerMetadata::createSymbolLayerWidget ( QgsVectorLayer )
inlineoverridevirtual

Create widget for symbol layer of this type. Can return NULL if there's no GUI.

Reimplemented from QgsSymbolLayerAbstractMetadata.

Definition at line 116 of file qgssymbollayerregistry.h.

◆ pathResolverFunction()

QgsSymbolLayerPathResolverFunc QgsSymbolLayerMetadata::pathResolverFunction ( ) const
inline
Note
not available in Python bindings

◆ resolvePaths()

void QgsSymbolLayerMetadata::resolvePaths ( QgsStringMap properties,
const QgsPathResolver pathResolver,
bool  saving 
)
inlineoverridevirtual

Resolve paths in symbol layer's properties (if there are any paths).

When saving is true, paths are converted from absolute to relative, when saving is false, paths are converted from relative to absolute. This ensures that paths in project files can be relative, but in symbol layer instances the paths are always absolute
