Member Enumeration Documentation

◆ CustomRole

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.

Definition at line 237 of file qgscoordinatereferencesystemmodel.cpp.

◆ columnCount()

int QgsCoordinateReferenceSystemModel::columnCount ( const QModelIndex &  = QModelIndex()) const
override

Definition at line 204 of file qgscoordinatereferencesystemmodel.cpp.

QVariant QgsCoordinateReferenceSystemModel::data ( const QModelIndex &  index,
int  role 
) const
override

Definition at line 58 of file qgscoordinatereferencesystemmodel.cpp.

◆ flags()

Qt::ItemFlags QgsCoordinateReferenceSystemModel::flags ( const QModelIndex &  index) const
override
