Add a high accuracy Add a non-high accuracy Remove the high accuracy -->we stay in high accuracy The problem is we have one client for all the controller, and the controller assume its client manage setEnableHighAccuracy per controller: void GeolocationController::removeObserver(Geolocation* observer) { if (!m_observers.contains(observer)) return; m_observers.remove(observer); m_highAccuracyObservers.remove(observer); if (m_client) { if (m_observers.isEmpty()) m_client->stopUpdating(); else if (m_highAccuracyObservers.isEmpty()) m_client->setEnableHighAccuracy(false); } }
