Collection of point cloud attributes.
A model for display of available attributes from a point cloud.
QgsPointCloudAttributeCollection attributes() const
Returns the attributes associated with the model.
bool allowEmptyAttributeName() const
Returns true if the model allows the empty attribute ("not set") choice.
A proxy model for filtering available attributes from a point cloud attribute model.
Filters filters() const
Returns the filters controlling displayed attributes.
QgsPointCloudAttributeModel * sourceAttributeModel()
Returns the QgsPointCloudAttributeModel used in this QSortFilterProxyModel.
Attribute for point cloud data pair of name and size in bytes.
DataType
Systems of unit measurement.
Represents a map layer supporting display of point clouds.
