Contains the configuration of a 3d axis.
void readXml(const QDomElement &element, const QgsReadWriteContext &context)
Reads settings from a DOM element.
@ Crs
Respect CRS directions.
@ Cube
Abstract cube mode.
bool operator!=(Qgs3DAxisSettings const &rhs) const
Returns true if objects are not equal.
void setMinViewportRatio(double ratio)
Sets the minimal axis viewport ratio between 0-1.
bool operator==(Qgs3DAxisSettings const &rhs) const
Returns true if both objects are equal.
void setMaxViewportRatio(double ratio)
Sets the maximal axis viewport ratio between 0-1.
void writeXml(QDomElement &element, const QgsReadWriteContext &context) const
Writes settings to a DOM element.
The class is used as a container of context for various read/write operations on other objects.
