Member Function Documentation

◆ calculateZRange()

QgsDoubleRange QgsMeshLayerElevationProperties::calculateZRange ( QgsMapLayer layer) const
overridevirtual

Attempts to calculate the overall elevation or z range for the specified layer, using the settings defined by this elevation properties object.

May return an infinite range if the extent could not be calculated.

Reimplemented from QgsMapLayerElevationProperties.

Definition at line 107 of file qgsmeshlayerelevationproperties.cpp.

◆ clone()

QgsMeshLayerElevationProperties * QgsMeshLayerElevationProperties::clone ( ) const
overridevirtual

Creates a clone of the properties.

Since
QGIS 3.26

Implements QgsMapLayerElevationProperties.

Definition at line 91 of file qgsmeshlayerelevationproperties.cpp.

◆ hasElevation()

bool QgsMeshLayerElevationProperties::hasElevation ( ) const
overridevirtual

Returns true if the layer has an elevation or z component.

Reimplemented from QgsMapLayerElevationProperties.

Definition at line 38 of file qgsmeshlayerelevationproperties.cpp.

◆ htmlSummary()

QString QgsMeshLayerElevationProperties::htmlSummary ( ) const
overridevirtual

Returns a HTML formatted summary of the properties.

Since
QGIS 3.26

Reimplemented from QgsMapLayerElevationProperties.

Definition at line 83 of file qgsmeshlayerelevationproperties.cpp.

◆ isVisibleInZRange()

bool QgsMeshLayerElevationProperties::isVisibleInZRange ( const QgsDoubleRange range) const
overridevirtual

Returns true if the layer should be visible and rendered for the specified z range.

Reimplemented from QgsMapLayerElevationProperties.

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.

See also
setProfileFillSymbol()

Definition at line 130 of file qgsmeshlayerelevationproperties.cpp.

◆ profileLineSymbol()

QgsLineSymbol * QgsMeshLayerElevationProperties::profileLineSymbol ( ) const

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

See also
setProfileLineSymbol()

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)

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

Ownership of symbol is transferred to the plot.

See also
profileLineSymbol()

Definition at line 123 of file qgsmeshlayerelevationproperties.cpp.

◆ setProfileSymbology()

void QgsMeshLayerElevationProperties::setProfileSymbology ( Qgis::ProfileSurfaceSymbology  symbology)

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

See also
setProfileSymbology()

◆ showByDefaultInElevationProfilePlots()

bool QgsMeshLayerElevationProperties::showByDefaultInElevationProfilePlots ( ) const
overridevirtual

Returns true if the layer should be visible by default in newly created elevation profile plots.

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().
