Definition at line 101 of file qgsmeshlayerelevationproperties.cpp.

◆ profileFillSymbol()

QgsFillSymbol * QgsMeshLayerElevationProperties::profileFillSymbol ( ) const

Returns the fill symbol used to render the mesh profile in elevation profile plots.

Definition at line 118 of file qgsmeshlayerelevationproperties.cpp.

◆ profileSymbology()

Qgis::ProfileSurfaceSymbology QgsMeshLayerElevationProperties::profileSymbology ( ) const

inline

Returns the symbology option used to render the mesh profile in elevation profile plots.

See also: setProfileSymbology()

Definition at line 96 of file qgsmeshlayerelevationproperties.h.

◆ readXml()

bool QgsMeshLayerElevationProperties::readXml	(	const QDomElement &	element,
		const QgsReadWriteContext &	context
	)

overridevirtual

Reads the elevation properties from a DOM element previously written by writeXml().

See also: writeXml()

Implements QgsMapLayerElevationProperties.

Definition at line 61 of file qgsmeshlayerelevationproperties.cpp.

◆ setProfileFillSymbol()

void QgsMeshLayerElevationProperties::setProfileFillSymbol ( QgsFillSymbol * symbol )

Sets the fill symbol used to render the mesh profile in elevation profile plots.

Ownership of symbol is transferred to the plot.

See also: profileFillSymbol()

Definition at line 135 of file qgsmeshlayerelevationproperties.cpp.

◆ setProfileLineSymbol()

void QgsMeshLayerElevationProperties::setProfileLineSymbol ( QgsLineSymbol * symbol )

Subclasses should override this with logic which determines whether the layer is likely desirable to be initially checked in these plots.

Since: QGIS 3.26

Reimplemented from QgsMapLayerElevationProperties.

Definition at line 113 of file qgsmeshlayerelevationproperties.cpp.

◆ writeXml()

QDomElement QgsMeshLayerElevationProperties::writeXml	(	QDomElement &	element,
		QDomDocument &	doc,
		const QgsReadWriteContext &	context
	)

overridevirtual

Writes the properties to a DOM element, to be used later with readXml().
