Instead, any connections and links to other items must be made in the finalizeRestoreFromXml() method. E.g. when restoring a scalebar, the connection to the linked map's signals should be implemented in finalizeRestoreFromXml(), not readPropertiesFromElement().

◆ refreshDataDefinedProperty()

void QgsLayoutItemElevationProfile::refreshDataDefinedProperty ( QgsLayoutObject::DataDefinedProperty  property = QgsLayoutObject::DataDefinedProperty::AllProperties)
overridevirtual

Refreshes a data defined property for the item by reevaluating the property's value and redrawing the item with this new value.

If property is set to QgsLayoutObject::AllProperties then all data defined properties for the item will be refreshed.

Reimplemented from QgsLayoutItem.

Definition at line 124 of file qgslayoutitemelevationprofile.cpp.

◆ requiresRasterization()

bool QgsLayoutItemElevationProfile::requiresRasterization ( ) const
overridevirtual

Returns true if the item is drawn in such a way that forces the whole layout to be rasterized when exporting to vector formats.

◆ setAtlasDriven()

void QgsLayoutItemElevationProfile::setAtlasDriven ( bool  enabled)

Sets whether the profile curve will follow the current atlas feature.

This requires an active layout atlas or report, using a line geometry type coverage layer.

◆ setCrs()

void QgsLayoutItemElevationProfile::setCrs ( const QgsCoordinateReferenceSystem crs)

Sets the desired Coordinate Reference System (crs) for the profile.

This also represents the CRS associated with the profileCurve().

◆ setDistanceUnit()

void QgsLayoutItemElevationProfile::setDistanceUnit ( Qgis::DistanceUnit  unit)

Sets the unit for the distance axis.

◆ setLayers()

void QgsLayoutItemElevationProfile::setLayers ( const QList< QgsMapLayer * > &  layers)

Sets the list of map layers participating in the elevation profile.

◆ setProfileCurve()

void QgsLayoutItemElevationProfile::setProfileCurve ( QgsCurve curve)

Sets the cross section profile curve, which represents the line along which the profile should be generated.

Ownership of curve is transferred to the item.

The coordinate reference system of the curve is set via setCrs().

◆ setTolerance()

void QgsLayoutItemElevationProfile::setTolerance ( double  tolerance)

Sets the tolerance of the request (in crs() units).

This value determines how far from the profileCurve() is appropriate for inclusion of results. For instance, when a profile is generated for a point vector layer this tolerance distance will dictate how far from the actual profile curve a point can reside within to be included in the results. Other sources may completely ignore this tolerance if it is not appropriate for the particular source.

tolerance()

◆ tolerance()

double QgsLayoutItemElevationProfile::tolerance ( ) const

Returns the tolerance of the request (in crs() units).

This value determines how far from the profileCurve() is appropriate for inclusion of results. For instance, when a profile is generated for a point vector layer this tolerance distance will dictate how far from the actual profile curve a point can reside within to be included in the results. Other sources may completely ignore this tolerance if it is not appropriate for the particular source.
