Detailed Description

Central Position Provider.

This class collects position data from the various sources (satellite, network, traffic receiver, …) chooses the best available source and exposes the data to QML and other parts of the program.

There exists one static instance of this class, which can be accessed via the method globalInstance(). No other instance of this class should be used.

Data from the standard operating system data source (typically: satnav or wifi) is only provided after startUpdates() has been called.

The methods in this class are reentrant, but not thread safe.

Property Documentation

◆ approximateLastValidCoordinate

QGeoCoordinate Positioning::PositionProvider::approximateLastValidCoordinate

read

Approximate last valid coordinate.

This property equals lastValidCoordinate, except that it is updated only every ten kilometers.

Definition at line 85 of file PositionProvider.h.

◆ lastValidCoordinate

QGeoCoordinate Positioning::PositionProvider::lastValidCoordinate

read

Last valid coordinate reading.

This property holds the last valid coordinate known. At the first start, this property is set to the location Freiburg Airport, EDTF. The value is stored in a QSetting at destruction, and restored in the construction.

Definition at line 94 of file PositionProvider.h.

◆ lastValidTT

Units::Angle Positioning::PositionProvider::lastValidTT

read

Last valid true track.

This property holds the last valid true track known. At the first start, this property is set to 0°. The value is stored in a QSetting at destruction, and restored in the construction.

Definition at line 102 of file PositionProvider.h.

◆ positionInfo

Positioning::PositionInfo Positioning::PositionProvider::positionInfo

read

Position information.

This property holds information about the device position. To ensure that the data is up-to-date, the position information will be set to an invalid positionInfo when no data has arrived for more than the time specified in PositionInfo::lifetime.

Definition at line 111 of file PositionProvider.h.

◆ pressureAltitude

Units::Distance Positioning::PositionProvider::pressureAltitude

read

Pressure altitude.

This property holds information about the pressure altitude. If the traffic data provider provides pressure altitude, then this is reported here. If the traffic data provider does not report pressure altitude AND the current aircraft is configured to use cabin pressure for pressure altitude, then cabin pressure is reported here.

Definition at line 121 of file PositionProvider.h.

◆ receivingPositionInfo

bool Positioning::PositionProvider::receivingPositionInfo

read

Indicator that position information is being received.

This is a shortcut for positionInfo().isValid. This property exists because it does not change so often, and can thus be more efficient to use.

Definition at line 129 of file PositionProvider.h.

◆ statusString

QString Positioning::PositionProvider::statusString

read

Source status.

This property holds a translated, human-readable string that describes the status of the positionInfo source. This could typically be a string of the form "OK" or "Insufficient permission to access position info"
