  • Method Details

    • run

      boolean run()

      The signal is emitted to notify that manager needs to start receiving position updates. After this signal is emitted the user should provide the updates using webkit_geolocation_manager_update_position() every time the position changes, or use webkit_geolocation_manager_failed() in case it isn't possible to determine the current position.

      If the signal is not handled, WebKit will try to determine the position using GeoClue if available.
