Detailed Description

Geographic position.

This class is a thin wrapper around QGeoPositionInfo. It exports the data from QGeoPositionInfo in a way that can be read from QML. In addition to QGeoPositionInfo, the class also contains information about the pressure altitude.

Returns

Coordinate

Definition at line 68 of file PositionInfo.h.

groundSpeed()

Q_INVOKABLE Units::Speed Positioning::PositionInfo::groundSpeed ( ) const

nodiscard

Ground speed.

Returns

Ground speed or NaN if unknown.

isValid()

Q_INVOKABLE bool Positioning::PositionInfo::isValid ( ) const

nodiscard

Validity.

Returns

True if the underlying QGeoPositionInfo is valid and if its age is less then PositionInfo::lifetime.

operator==()

Q_INVOKABLE bool Positioning::PositionInfo::operator== ( const Positioning::PositionInfo & rhs ) const

inline

Comparison: equal.

Parameters

rhs	Right hand side of the comparison

Returns

Result of the comparison

Definition at line 96 of file PositionInfo.h.

terrainElevationAMSL()

Q_INVOKABLE Units::Distance Positioning::PositionInfo::terrainElevationAMSL ( )

nodiscard

Elevation of terrain at a given coordinate, above sea level.

Returns

Elevation of the terrain at position, or NaN if the terrain elevation is unknown

timestamp()

Q_INVOKABLE QDateTime Positioning::PositionInfo::timestamp ( ) const

inlinenodiscard

Timestamp.

Returns

Timestamp of the position info.

Definition at line 109 of file PositionInfo.h.
