The Qt Location module offers location based features such as GPS support. It is based on the Base module.
The following configure line can be used to build the Base and Location module only:
./configure -modules location -device xyz
Note that not specifying a device profile would result in the reference device being build.
The Qt Extended Location support is provided by this module.
| Feature | Details |
|---|---|
| Client API | The client API provides classes for general purpose location information. |
| Backend support | The Client API uses a plug-in based factory mechanism which can be used to extend the potential sources for location data. By default Qt Extended comes with in-built NMEA support. |
The Location module includes the following software components:
The exact list of components included in this module can be found in $QPEDIR/src/module_location.pri.
The test plan for the Location module summarizes the Quality Assurance procedures for this module. The results of these test are available here.
