A phone usually has a built-in GPS modem but also other sources of positioning information, so I will use Android for this example. The main Qt classes we will look at are as follows:
Here are the Qt Positioning APIs:
QGeoSatelliteInfoQGeoLocationQGeoPositionInfoSourceQGeoCoordinate
And here are the Qt Location APIs:
QPlaceSearchResultQPlaceContentQGeoRoute
First, we need to edit the .pro file and add QT += positioning.
You can show the user satellite information by using QGeoSatelliteInfoSource, which has a static method to get QGeoSatelliteInfoSource.
Note
The source code can be found on the Git repository under the Chapter08-1 directory, in the cp8 branch.
We will start by calling QGeoSatelliteInfoSource::createDefaultSource.
QGeoSatelliteInfoSource*source = QGeoSatelliteInfoSource::createDefaultSource(this);
