Member Function Documentation

◆ error()

QGeoPositionInfoSource::Error QGeoPositionInfoSourceGeoclue2::error ( ) const

overridevirtual

Returns the type of error that last occurred.

Note: Since Qt6 the last error is always reset when calling startUpdates() or requestUpdate().

Implements QGeoPositionInfoSource.

Definition at line 120 of file qgeopositioninfosource_geoclue2.cpp.

◆ lastKnownPosition()

QGeoPositionInfo QGeoPositionInfoSourceGeoclue2::lastKnownPosition ( bool fromSatellitePositioningMethodsOnly = false ) const

overridevirtual

Returns an update containing the last known position, or a null update if none is available.

If fromSatellitePositioningMethodsOnly is true, this returns the last known position received from a satellite positioning method; if none is available, a null update is returned.

Implements QGeoPositionInfoSource.

Definition at line 79 of file qgeopositioninfosource_geoclue2.cpp.

◆ minimumUpdateInterval()

int QGeoPositionInfoSourceGeoclue2::minimumUpdateInterval ( ) const

overridevirtual

Implements QGeoPositionInfoSource.

Definition at line 115 of file qgeopositioninfosource_geoclue2.cpp.

References MINIMUM_UPDATE_INTERVAL.

Referenced by requestUpdate().

Here is the caller graph for this function:

◆ requestUpdate()

void QGeoPositionInfoSourceGeoclue2::requestUpdate ( int timeout = 5000 )

overridevirtual

Attempts to get the current position and emit positionUpdated() with this information.

If the current position cannot be found within the given timeout (in milliseconds) or if timeout is less than the value returned by minimumUpdateInterval(), an errorOccurred() signal with the \l {QGeoPositionInfoSource::}{UpdateTimeoutError} is emitted.

If the timeout is zero, the timeout defaults to a reasonable timeout period as appropriate for the source.

This does nothing if another update request is in progress. However it can be called even if startUpdates() has already been called and regular updates are in progress.

If the source uses multiple positioning methods, it tries to get the current position from the most accurate positioning method within the given timeout.

Note: Since Qt6 this method always resets the last error to \l {QGeoPositionInfoSource::}{NoError} before requesting the position.; To understand how to use this method from an Android service, see \l {Qt Positioning on Android}.

Here is the call graph for this function:

◆ setUpdateInterval()

void QGeoPositionInfoSourceGeoclue2::setUpdateInterval ( int msec )

overridevirtual

Reimplemented from QGeoPositionInfoSource.

Definition at line 73 of file qgeopositioninfosource_geoclue2.cpp.

References QGeoPositionInfoSource::setUpdateInterval().

Here is the call graph for this function:

◆ startUpdates()

void QGeoPositionInfoSourceGeoclue2::startUpdates ( )

overridevirtual

Starts emitting updates at regular intervals as specified by setUpdateInterval().

If setUpdateInterval() has not been called, the source will emit updates as soon as they become available.

An errorOccurred() signal with the \l {QGeoPositionInfoSource::} {UpdateTimeoutError} will be emitted if this QGeoPositionInfoSource subclass determines that it will not be able to provide regular updates. This could happen if a satellite fix is lost or if a hardware error is detected. Position updates will recommence if the data becomes available later on. The \l {QGeoPositionInfoSource::}{UpdateTimeoutError} error will not be emitted again until after the periodic updates resume.

Note: Since Qt6 this method always resets the last error to \l {QGeoPositionInfoSource::}{NoError} before starting the updates.; To understand how to use this method from an Android service, see \l {Qt Positioning on Android}.

On iOS, starting from version 8, Core Location framework requires additional entries in the application's Info.plist with keys NSLocationAlwaysUsageDescription or NSLocationWhenInUseUsageDescription and a string to be displayed in the authorization prompt. The key NSLocationWhenInUseUsageDescription is used when requesting permission to use location services while the app is in the foreground. The key NSLocationAlwaysUsageDescription is used when requesting permission to use location services whenever the app is running (both the foreground and the background). If both entries are defined, NSLocationWhenInUseUsageDescription has a priority in the foreground mode.

Here is the call graph for this function:

◆ stopUpdates()

void QGeoPositionInfoSourceGeoclue2::stopUpdates ( )

overridevirtual

Stops emitting updates at regular intervals.

Implements QGeoPositionInfoSource.

Definition at line 146 of file qgeopositioninfosource_geoclue2.cpp.

References qCDebug, and qCWarning.

◆ supportedPositioningMethods()

QGeoPositionInfoSourceGeoclue2::PositioningMethods QGeoPositionInfoSourceGeoclue2::supportedPositioningMethods ( ) const

overridevirtual

Returns the positioning methods available to this source.

Availability is defined as being usable at the time of calling this function. Therefore user settings like turned off location service or limitations to Satellite-based position providers are reflected by this function. Runtime notifications when the status changes can be obtained via \l supportedPositioningMethodsChanged().

Not all platforms distinguish the different positioning methods or communicate the current user configuration of the device. The following table provides an overview of the current platform situation:
