Member Enumeration Documentation

CustomRole

enum class QgsCoordinateReferenceSystemModel::CustomRole : int

strong

Custom model roles.

Note

Prior to QGIS 3.36 this was available as QgsCoordinateReferenceSystemModel::Roles

Since

QGIS 3.36

Enumerator
NodeType	Corresponds to the node's type.
Name	The coordinate reference system name.
AuthId	The coordinate reference system authority name and id.
Deprecated	true if the CRS is deprecated
Type	The coordinate reference system type.
GroupId	The node ID (for group nodes)
Wkt	The coordinate reference system's WKT representation. This is only used for non-standard CRS (i.e. those not present in the database).
Proj	The coordinate reference system's PROJ representation. This is only used for non-standard CRS (i.e. those not present in the database).

Constructor & Destructor Documentation

QgsCoordinateReferenceSystemModel()

QgsCoordinateReferenceSystemModel::QgsCoordinateReferenceSystemModel

(

QObject *

parent = nullptr

)

Constructor for QgsCoordinateReferenceSystemModel, with the specified parent object.

Definition at line 24 of file qgscoordinatereferencesystemmodel.cpp.

Member Function Documentation

addCustomCrs()

QModelIndex QgsCoordinateReferenceSystemModel::addCustomCrs

(

const QgsCoordinateReferenceSystem &

crs

)

Adds a custom crs to the model.

This method can be used to add CRS which aren't present in either the standard PROJ SRS database or the user's custom CRS database to the model.

Definition at line 461 of file qgscoordinatereferencesystemmodel.cpp.

authIdToIndex()

QModelIndex QgsCoordinateReferenceSystemModel::authIdToIndex

(

const QString &

authId

)

const

Retrieves the model index corresponding to a CRS with the specified authId.

Returns an invalid index if the CRS was not found.
