class CustomRole(value)

Bases: enum.IntEnum

Custom model roles.

Note

Prior to QGIS 3.36 this was available as QgsCoordinateReferenceSystemModel.Roles

Added in version 3.36.

• RoleNodeType: Corresponds to the node’s type

• RoleName: The coordinate reference system name

• RoleAuthId: The coordinate reference system authority name and id

• RoleDeprecated: True if the CRS is deprecated

• RoleType: The coordinate reference system type

• RoleGroupId: The node ID (for group nodes)

• RoleWkt: The coordinate reference system’s WKT representation. This is only used for non-standard CRS (i.e. those not present in the database).

• RoleProj: The coordinate reference system’s PROJ representation. This is only used for non-standard CRS (i.e. those not present in the database).

addCustomCrs(self, crs: QgsCoordinateReferenceSystem) → QModelIndex

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.

Parameters:

crs (QgsCoordinateReferenceSystem)

Return type:

QModelIndex

authIdToIndex(self, authId: str) → QModelIndex

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

Returns an invalid index if the CRS was not found.

Parameters:

authId (str)

Return type:

QModelIndex

beginInsertColumns(self, QModelIndex, int, int)

beginInsertRows(self, QModelIndex, int, int)

changePersistentIndex(self, QModelIndex, QModelIndex)

changePersistentIndexList(self, Iterable[QModelIndex], Iterable[QModelIndex])

childEvent(self, QChildEvent)

columnCount(self, QModelIndex=QModelIndex()) → int

Return type:

int

connectNotify(self, QMetaMethod)

createIndex(self, int, int, object: object = 0) → QModelIndex
