Detailed Description

Registry of available symbol layer classes.

QgsSymbolLayerRegistry is not usually directly created, but rather accessed through QgsApplication::symbolLayerRegistry().

Definition at line 144 of file qgssymbollayerregistry.h.

Constructor & Destructor Documentation

◆ QgsSymbolLayerRegistry() [1/2]

QgsSymbolLayerRegistry::QgsSymbolLayerRegistry ( )

Definition at line 26 of file qgssymbollayerregistry.cpp.

◆ ~QgsSymbolLayerRegistry()

QgsSymbolLayerRegistry::~QgsSymbolLayerRegistry ( )

Definition at line 69 of file qgssymbollayerregistry.cpp.

◆ QgsSymbolLayerRegistry() [2/2]

QgsSymbolLayerRegistry::QgsSymbolLayerRegistry ( const QgsSymbolLayerRegistry rh)

QgsSymbolLayerRegistry cannot be copied.

Member Function Documentation

◆ addSymbolLayerType()

bool QgsSymbolLayerRegistry::addSymbolLayerType ( QgsSymbolLayerAbstractMetadata metadata)

register a new symbol layer type. Takes ownership of the metadata instance.

Definition at line 74 of file qgssymbollayerregistry.cpp.

◆ createSymbolLayer()

QgsSymbolLayer * QgsSymbolLayerRegistry::createSymbolLayer ( const QString &  name,
const QgsStringMap properties = QgsStringMap() 
) const

create a new instance of symbol layer given symbol layer name and properties

Definition at line 110 of file qgssymbollayerregistry.cpp.

◆ createSymbolLayerFromSld()

QgsSymbolLayer * QgsSymbolLayerRegistry::createSymbolLayerFromSld ( const QString &  name,
QDomElement &  element 
) const

create a new instance of symbol layer given symbol layer name and SLD

Definition at line 118 of file qgssymbollayerregistry.cpp.

◆ defaultSymbolLayer()

QgsSymbolLayer * QgsSymbolLayerRegistry::defaultSymbolLayer ( QgsSymbol::SymbolType  type)
static

create a new instance of symbol layer for specified symbol type with default settings

Definition at line 89 of file qgssymbollayerregistry.cpp.

◆ operator=()

QgsSymbolLayerRegistry& QgsSymbolLayerRegistry::operator= ( const QgsSymbolLayerRegistry rh)
delete

QgsSymbolLayerRegistry cannot be copied.

◆ resolvePaths()

void QgsSymbolLayerRegistry::resolvePaths ( const QString &  name,
QgsStringMap properties,
const QgsPathResolver pathResolver,
bool  saving 
) const

Resolve paths in properties of a particular symbol layer.

This normally means converting relative paths to absolute paths when loading and converting absolute paths to relative paths when saving.

Since
QGIS 3.0

Definition at line 126 of file qgssymbollayerregistry.cpp.

◆ symbolLayerMetadata()

QgsSymbolLayerAbstractMetadata * QgsSymbolLayerRegistry::symbolLayerMetadata ( const QString &  name) const

Returns metadata for specified symbol layer. Returns NULL if not found.

Definition at line 84 of file qgssymbollayerregistry.cpp.

◆ symbolLayersForType()

QStringList QgsSymbolLayerRegistry::symbolLayersForType ( QgsSymbol::SymbolType  type)

Returns a list of available symbol layers for a specified symbol type.
