bool QgsCentroidFillSymbolLayer::hasDataDefinedProperties ( ) const

overridevirtual

Returns true if the symbol layer (or any of its sub-symbols) contains data defined properties.

Since: QGIS 3.4.5

Reimplemented from QgsSymbolLayer.

Definition at line 3555 of file qgsfillsymbollayer.cpp.

QString QgsCentroidFillSymbolLayer::layerType ( ) const

overridevirtual

Returns a string that represents this layer type.

Used for serialization. Should match with the string used to register this symbol layer in the registry.

Implements QgsSymbolLayer.

Definition at line 3411 of file qgsfillsymbollayer.cpp.

QgsMapUnitScale QgsCentroidFillSymbolLayer::mapUnitScale ( ) const

overridevirtual
