enum QGeoSatelliteInfo:: 屬性

定義用於衛星信息的屬性。

常量	值	描述
QGeoSatelliteInfo::Elevation	0	衛星仰角 (以度為單位)。
QGeoSatelliteInfo::Azimuth	1	正北方位角 (以度為單位)。

enum QGeoSatelliteInfo:: SatelliteSystem

定義衛星的 GNSS 係統。

常量	值	描述
QGeoSatelliteInfo::Undefined	0x00	未定義。
QGeoSatelliteInfo::GPS	0x01	全球定位係統 (USA 美國)。
QGeoSatelliteInfo::GLONASS	0x02	全球定位係統 (俄羅斯)。
QGeoSatelliteInfo::GALILEO	0x03	全球導航衛星係統 (EU 歐盟)。
QGeoSatelliteInfo::BEIDOU	0x04	北鬥導航衛星係統 (中國)。
QGeoSatelliteInfo::QZSS	0x05	準天頂衛星係統 (日本)。
QGeoSatelliteInfo::Multiple	0xFF	This type normally indicates that the information is received from a device that supports multiple satellite systems, and the satellite system is not explicitly specified. Depending on the data source, you might use other information to determine the actual system type. One example of the usage of this type is an NMEA $GNGSA message, which contains the IDs of the satellites being used, but does not explicitly mention their system types.
QGeoSatelliteInfo::CustomType	0x100	The first type that can be used for user purposes. For example when reimplementing NMEA data parsing in QNmeaSatelliteInfoSource . User can add more types using CustomType + 1 , CustomType + 2 and so on.

[read-only] satelliteIdentifier : const int

This property holds the satellite identifier number.

The satellite identifier number can be used to identify a satellite within the satellite system.

The actual value may vary, depending on the platform and the selected backend.

例如，若 nmea plugin is used, the satellite identifier for GPS satellite system represents the PRN (Pseudo-random noise) number, and the satellite identifier for GLONASS satellite system represents the slot number.

For NMEA-based backends the satellite identifier can be used to determine the satellite system type if it is not available from other sources. You can refer to satellite IDs list to check the ID ranges for different satellite systems.

注意： Depending on the platform and the selected backend, the satellite identifier ranges for different satellite systems may intersect. To uniquely identify a satellite, a combination of satelliteIndetifier() and satelliteSystem () must be used.

int	satelliteIdentifier () const

QGeoSatelliteInfo:: QGeoSatelliteInfo ()

創建衛星信息對象。

QGeoSatelliteInfo:: QGeoSatelliteInfo (const QGeoSatelliteInfo & other )

創建衛星信息對象采用值為 other .

[noexcept, since 6.2] QGeoSatelliteInfo:: QGeoSatelliteInfo ( QGeoSatelliteInfo && other )

創建衛星信息對象通過移動自 other .

Note that a moved-from QGeoSatelliteInfo can only be destroyed or assigned to. The effect of calling other functions than the destructor or one of the assignment operators is undefined.

該函數在 Qt 6.2 引入。

[noexcept] QGeoSatelliteInfo:: ~QGeoSatelliteInfo ()

銷毀衛星信息對象。

[invokable] qreal QGeoSatelliteInfo:: 屬性 ( QGeoSatelliteInfo::Attribute attribute ) const

返迴值為指定 attribute 如 qreal 值。

返迴 -1 若值未設置。

注意： 此函數可以被援引，通過元對象係統和從 QML。見 Q_INVOKABLE .

另請參閱 hasAttribute () 和 setAttribute ().

[invokable] bool QGeoSatelliteInfo:: hasAttribute ( QGeoSatelliteInfo::Attribute attribute ) const

返迴 true 若指定 attribute 呈現在此更新中。

注意： 此函數可以被援引，通過元對象係統和從 QML。見 Q_INVOKABLE .

void QGeoSatelliteInfo:: removeAttribute ( QGeoSatelliteInfo::Attribute attribute )

移除指定 attribute 及其值。

int QGeoSatelliteInfo:: satelliteIdentifier () const

返迴衛星標識符編號。

注意： getter 函數對於特性 satelliteIdentifier。

另請參閱 setSatelliteIdentifier () 和 satelliteSystem ().

QGeoSatelliteInfo::SatelliteSystem QGeoSatelliteInfo:: satelliteSystem () const

返迴衛星係統 (GPS、GLONASS...)

注意： 此值可以一起用於 satelliteIdentifier () 以唯一標識衛星。

注意： getter 函數對於特性 satelliteSystem。

另請參閱 setSatelliteSystem () 和 satelliteIdentifier ().

void QGeoSatelliteInfo:: setAttribute ( QGeoSatelliteInfo::Attribute attribute , qreal value )

設置值為 attribute to value .

另請參閱 attribute ().

void QGeoSatelliteInfo:: setSatelliteIdentifier ( int satId )

將衛星標識編號設為 satId .

The satellite identifier number can be used to identify a satellite within the satellite system.

The actual value may vary, depending on the platform and the selected backend.

例如，若 nmea plugin is used, the satellite identifier for GPS satellite system represents the PRN (Pseudo-random noise) number, and the satellite identifier for GLONASS satellite system represents the slot number.

另請參閱 satelliteIdentifier ().

void QGeoSatelliteInfo:: setSatelliteSystem ( QGeoSatelliteInfo::SatelliteSystem system )

設置衛星係統 (GPS、GLONASS...) 為 system .

另請參閱 satelliteSystem ().

void QGeoSatelliteInfo:: setSignalStrength ( int signalStrength )

將信號強度設為 signalStrength (以分貝為單位)。

另請參閱 signalStrength ().

int QGeoSatelliteInfo:: signalStrength () const

Returns the signal strength, or -1 if the value has not been set.

注意： getter 函數對於特性 signalStrength。

另請參閱 setSignalStrength ().

[noexcept, since 6.2] void QGeoSatelliteInfo:: swap ( QGeoSatelliteInfo & other )

Swaps this satellite information with other 。此操作很快且從不失敗。

該函數在 Qt 6.2 引入。

[noexcept, since 6.2] QGeoSatelliteInfo &QGeoSatelliteInfo:: operator= ( QGeoSatelliteInfo && other )

Move-assigns the value from other to this object

Note that a moved-from QGeoSatelliteInfo can only be destroyed or assigned to. The effect of calling other functions than the destructor or one of the assignment operators is undefined.
