The location class provides the functions required for determining the users location.
It handles how the location should be retrieved and calls the corresponding functions (WLAN or GPS). It also includes the code for wlan scanning geopositining and major parts of GPS related code.
BETA class: not rules define when to use GPS, thus only WLAN will be used Issue: If error in wlan scanning, a default mac will be sent. (Because the emulator does not support wlan scanning)
| QGeoCoordinate Location::getCacheCenter | ( | ) |
Get the cache's center.
| void Location::recvGeoAnswer | ( | QNetworkReply * | networkReply | ) | [slot] |
Process answer received from geolocation service.
is a pointer to the object that contains the network reply Called by an instance of QNetworkReply if it receives and async answer from the geolocation service containing the current position. The result is sent as signal to the calling class.
| void Location::sendGeoRequest | ( | ) |
Request location: send wifi & cell tower information to the geolocation service.
Send a list of detected APs and Cell Tower infrormation the Geolocation service. The geolocation provider will also read and analyze the current IP address.
| void Location::setCacheCenter | ( | double | lat, | |
| double | lng | |||
| ) | [slot] |
Set the center of the cache.
| lat | is the latitude | |
| lng | is the longitude |
| void Location::setMode | ( | int | m | ) |
Set localization mode.
| m | is the mode |
| void Location::setNbTraces | ( | int | nb | ) |
Set the number of dummies.
| nb | is the number |
| void Location::setNoGps | ( | QString | reason | ) | [slot] |
Emit a signal that GPS is not available.
| reson | indicates the reason |
| void Location::setStatus | ( | QString | msg | ) | [slot] |
Emit a signal with the status.
is the msg send
| void Location::updateLocation | ( | double | lat, | |
| double | lon | |||
| ) | [slot] |
Emit a signal with the new location information.
| lat | is the latitude | |
| lon | is the longitude |
| void Location::updateProgress | ( | QString | src | ) | [slot] |
Slot called on update of progress.
| src | indicates the source who updates the progress |
