QgsRange which stores a range of double values.
Definition: qgsrange.h:231
Base class for storage of map layer elevation properties.
void zScaleChanged()
Emitted when the z scale changes.
QgsPropertyCollection mDataDefinedProperties
Property collection for data defined elevation settings.
void profileGenerationPropertyChanged()
Emitted when any of the elevation properties which relate solely to generation of elevation profiles ...
virtual QgsMapLayerElevationProperties::Flags flags() const
Returns flags associated to the elevation properties.
virtual QgsMapLayerElevationProperties * clone() const =0
Creates a clone of the properties.
QgsPropertyCollection & dataDefinedProperties()
Returns a reference to the object's property collection, used for data defined overrides.
void changed()
Emitted when any of the elevation properties have changed.
void profileRenderingPropertyChanged()
Emitted when any of the elevation properties which relate solely to presentation of elevation results...
const QgsPropertyCollection & dataDefinedProperties() const
Returns a reference to the object's property collection, used for data defined overrides.
void zOffsetChanged()
Emitted when the z offset changes.
double zScale() const
Returns the z scale, which is a scaling factor which should be applied to z values from the layer.
virtual QDomElement writeXml(QDomElement &element, QDomDocument &doc, const QgsReadWriteContext &context)=0
Writes the properties to a DOM element, to be used later with readXml().
static QgsPropertiesDefinition sPropertyDefinitions
Property definitions.
virtual bool readXml(const QDomElement &element, const QgsReadWriteContext &context)=0
Reads the elevation properties from a DOM element previously written by writeXml().
Flag
Flags attached to the elevation property.
double zOffset() const
Returns the z offset, which is a fixed offset amount which should be added to z values from the layer...
Base class for all map layer types.
Definition: qgsmaplayer.h:75
A grouped map of multiple QgsProperty objects, each referenced by a integer key value.
The class is used as a container of context for various read/write operations on other objects.
