Description

This factory manages the create of ChamplainMapSource. It contains names and constructor functions for each available map sources in libchamplain. You can add your own with champlain_map_source_factory_register.

To get the wanted map source, use champlain_map_source_factory_create. It will return a ready to use ChamplainMapSource.

To get the list of registered map sources, use champlain_map_source_factory_get_registered.

Functions

champlain_map_source_factory_dup_default ()
