Detailed Description

Stores metadata about one symbol layer class.

Note

It's necessary to implement createSymbolLayer() function. In C++ you can use QgsSymbolLayerMetadata convenience class.

Member Function Documentation

createSymbolLayer()

virtual QgsSymbolLayer* QgsSymbolLayerAbstractMetadata::createSymbolLayer ( const QgsStringMap &  map )

pure virtual

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

Implemented in QgsSymbolLayerMetadata.

createSymbolLayerFromSld()

virtual QgsSymbolLayer* QgsSymbolLayerAbstractMetadata::createSymbolLayerFromSld ( QDomElement &  )

inlinevirtual

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

Reimplemented in QgsSymbolLayerMetadata.

Definition at line 54 of file qgssymbollayerregistry.h.

createSymbolLayerWidget()

virtual QgsSymbolLayerWidget* QgsSymbolLayerAbstractMetadata::createSymbolLayerWidget ( QgsVectorLayer *  )

inlinevirtual

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

Reimplemented in QgsSymbolLayerMetadata.

Definition at line 52 of file qgssymbollayerregistry.h.

name()

QString QgsSymbolLayerAbstractMetadata::name ( ) const

inline

Definition at line 45 of file qgssymbollayerregistry.h.

resolvePaths()

virtual void QgsSymbolLayerAbstractMetadata::resolvePaths ( QgsStringMap &  properties, const QgsPathResolver &  pathResolver, bool  saving  )

inlinevirtual

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

Since
