Detailed Description

\inmodule QtPositioning

Since: 5.2

The QGeoAreaMonitorSource class enables the detection of proximity changes for a specified set of coordinates.

A QGeoAreaMonitorSource emits signals when the current position is in range, or has moved out of range, of a specified area. Each area is specified by a \l QGeoAreaMonitorInfo object. For example:

QGeoAreaMonitorSource follows a singleton pattern. Each instance of the class with the same \l sourceName() shares the same area monitoring backend. If a new \l QGeoAreaMonitorInfo object is added via \l startMonitoring() or \l requestUpdate() it can be retrieved by another instance of this class (provided that they are sourced from the same area monitor provider plug-in). The same singleton pattern applies to the \l QGeoPositionInfoSource instance used by this class. The following code snippet emphasizes the behavior:

QGeoAreaMonitorSource *s1 = QGeoAreaMonitorSource::createSource("blah", this);
QGeoAreaMonitorSource *s2 = QGeoAreaMonitorSource::createSource("blah", this);
QVERIFY(s1->positionInfoSource() == s2->positionInfoSource);

Member Function Documentation

◆ activeMonitors() [1/2]

QList< QGeoAreaMonitorInfo > QGeoAreaMonitorSource::activeMonitors ( ) const

pure virtual

Returns the list of all active monitors known to the QGeoAreaMonitorSource object.

An active monitor was started via startMonitoring(). For every active monitor the source object will emit the required signals, such as areaEntered() or areaExited(). Multiple \l QGeoAreaMonitorSource instances within the same application share the same active monitor objects.

Unless an active QGeoAreaMonitorInfo \l {QGeoAreaMonitorInfo::isPersistent()}{isPersistent()} an active QGeoAreaMonitorInfo will be stopped once the current application terminates.

Implemented in QGeoAreaMonitorPolling.

◆ activeMonitors() [2/2]

QList< QGeoAreaMonitorInfo > QGeoAreaMonitorSource::activeMonitors ( const QGeoShape & lookupArea ) const

pure virtual

Returns the list of all active monitors known to the QGeoAreaMonitorSource object whose center lies within lookupArea.

If lookupArea is empty the returned list will be empty.

An active monitor was started via startMonitoring(). For every active monitor the source object will emit the required signals, such as areaEntered() or areaExited(). Multiple \l QGeoAreaMonitorSource instances within the same application share the same active monitor objects.

Unless an active QGeoAreaMonitorInfo \l {QGeoAreaMonitorInfo::isPersistent()}{isPersistent()} an active QGeoAreaMonitorInfo will be stopped once the current application terminates.

Implemented in QGeoAreaMonitorPolling.

◆ areaEntered

void QGeoAreaMonitorSource::areaEntered	(	const QGeoAreaMonitorInfo &	monitor,
		const QGeoPositionInfo &	update )

signal

Emitted when the current position has moved from a position outside of the active monitor to a position within the monitored area.

The update holds the new position.

◆ error()

QGeoAreaMonitorSource::Error QGeoAreaMonitorSource::error ( ) const

pure virtual

Returns the type of error that last occurred.

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

Implemented in QGeoAreaMonitorPolling.

◆ errorOccurred

void QGeoAreaMonitorSource::errorOccurred ( QGeoAreaMonitorSource::Error areaMonitoringError )

signal

This signal is emitted after an error occurred.

The areaMonitoringError parameter describes the type of error that occurred.

◆ monitorExpired

void QGeoAreaMonitorSource::monitorExpired ( const QGeoAreaMonitorInfo & monitor )

signal

Emitted when monitor has expired.

An expired area monitor is automatically removed from the list of \l activeMonitors().

See also: activeMonitors()

Referenced by monitorExpiredSignal().

Here is the caller graph for this function:

◆ positionInfoSource()

QGeoPositionInfoSource * QGeoAreaMonitorSource::positionInfoSource ( ) const

virtual

Returns the current QGeoPositionInfoSource used by this QGeoAreaMonitorSource object.

The function will return \l QGeoPositionInfoSource::createDefaultSource() if no other object has been set.

The function returns nullptr if not even a default QGeoPositionInfoSource exists.

Any usage of the returned \l QGeoPositionInfoSource instance should account for the fact that it may reside in a different thread.

See also: QGeoPositionInfoSource, setPositionInfoSource()

Reimplemented in QGeoAreaMonitorPolling.

Definition at line 229 of file qgeoareamonitorsource.cpp.

References d.

◆ requestUpdate()

bool QGeoAreaMonitorSource::requestUpdate	(	const QGeoAreaMonitorInfo &	monitor,
		const char *	signal )

pure virtual

Enables single shot area monitoring.

Area monitoring for monitor will be performed until this QGeoAreaMonitorSource instance emits signal for the first time. Once the signal was emitted, monitor is automatically removed from the list of \l activeMonitors(). If monitor is invalid or has an expiry date that has been passed, this function returns false.

QGeoAreaMonitor singleShotMonitor;
QGeoAreaMonitorSource * source = QGeoAreaMonitorSource::createDefaultSource(this);
//...
bool ret = source->requestUpdate(singleShotMonitor,
                      SIGNAL(areaExited(QGeoAreaMonitor,QGeoPositionInfo)));

The above singleShotMonitor object will cease to send updates once the \l areaExited() signal was emitted for the first time. Until this point in time any other signal may be emitted zero or more times depending on the area context.

It is not possible to simultanously request updates for more than one signal of the same monitor object. The last call to this function determines the signal upon which the updates cease to continue. At this stage only the \l areaEntered() and \l areaExited() signals can be used to terminate the monitoring process.

Requesting persistent monitoring on a QGeoAreaMonitorSource instance fails if the area monitoring backend doesn't support \l QGeoAreaMonitorSource::PersistentAreaMonitorFeature.

If monitor was already registered via \l startMonitoring() it is converted to a single shot behavior.

Note: Since Qt6 this method always resets the last error to \l {QGeoAreaMonitorSource::}{NoError} before starting monitoring.

See also: startMonitoring(), stopMonitoring()

Implemented in QGeoAreaMonitorPolling.

◆ setBackendProperty()

bool QGeoAreaMonitorSource::setBackendProperty	(	const QString &	name,
		const QVariant &	value )

virtual

Since: 6.2

Sets the backend-specific property named name to value. Returns true on success, otherwise returns false. Backend-specific properties can be used to configure the area monitoring subsystem behavior at runtime.

See also: backendProperty()

Definition at line 195 of file qgeoareamonitorsource.cpp.

References Q_UNUSED.

◆ setPositionInfoSource()

void QGeoAreaMonitorSource::setPositionInfoSource ( QGeoPositionInfoSource * newSource )

virtual

Sets the new \l QGeoPositionInfoSource to be used by this QGeoAreaMonitorSource object.

The area monitoring backend becomes the new QObject parent for newSource. The previous \l QGeoPositionInfoSource object will be deleted. All QGeoAreaMonitorSource instances based on the same \l sourceName() share the same QGeoPositionInfoSource instance.

This may be useful when it is desirable to manipulate the positioning system used by the area monitoring engine.

Note that ownership must be taken care of by subclasses of QGeoAreaMonitorSource. Due to the singleton pattern behind this class newSource may be moved to a new thread.

See also: positionInfoSource()

Reimplemented in QGeoAreaMonitorPolling.

Definition at line 251 of file qgeoareamonitorsource.cpp.

References d.

◆ sourceName()

QString QGeoAreaMonitorSource::sourceName ( ) const

Returns the unique name of the area monitor source implementation in use.

This is the same name that can be passed to createSource() in order to create a new instance of a particular area monitor source implementation.

Definition at line 179 of file qgeoareamonitorsource.cpp.

References d.

Referenced by createSource().

Here is the caller graph for this function:

◆ startMonitoring()

bool QGeoAreaMonitorSource::startMonitoring ( const QGeoAreaMonitorInfo & monitor )

pure virtual

Returns true if the monitoring of monitor could be successfully started; otherwise returns false.

A reason for not being able to start monitoring could be the unavailability of an appropriate default position info source while no alternative QGeoPositionInfoSource has been set via \l setPositionInfoSource().

If monitor is already active, the existing monitor object will be replaced by the new monitor reference. The identification of QGeoAreaMonitorInfo instances happens via \l QGeoAreaMonitorInfo::identifier(). Therefore this function can also be used to update active monitors.

If monitor has an expiry date that has been passed this function returns false. Calling this function for an already via \l requestUpdate() registered single shot monitor switches the monitor to a permanent monitoring mode.

Requesting persistent monitoring on a QGeoAreaMonitorSource instance fails if the area monitoring backend doesn't support \l QGeoAreaMonitorSource::PersistentAreaMonitorFeature.

Note: Since Qt6 this method always resets the last error to \l {QGeoAreaMonitorSource::}{NoError} before starting monitoring.

See also: stopMonitoring()

Implemented in QGeoAreaMonitorPolling.

Referenced by MyClass::MyClass().

Here is the caller graph for this function:

◆ stopMonitoring()

bool QGeoAreaMonitorSource::stopMonitoring ( const QGeoAreaMonitorInfo & monitor )

pure virtual

Returns true if monitor was successfully removed from the list of \l activeMonitors(); otherwise returns false.

This behavior is independent on whether monitor was registered via \l startMonitoring() or \l requestUpdate().

Implemented in QGeoAreaMonitorPolling.

◆ supportedAreaMonitorFeatures()

AreaMonitoringFeatures QGeoAreaMonitorSource::supportedAreaMonitorFeatures ( ) const

pure virtual

Returns the area monitoring features available to this source.

Implemented in QGeoAreaMonitorPolling.
