The QRotationSensor class is a convenience wrapper around QSensor . 更多...
| 頭: |
#include <QRotationSensor>
|
| CMake: |
find_package(Qt6 REQUIRED COMPONENTS Sensors)
target_link_libraries(mytarget PRIVATE Qt6::Sensors)
|
| qmake: |
QT += sensors
|
| 繼承: | QSensor |
| QRotationSensor (QObject * parent = nullptr) | |
| virtual | ~QRotationSensor () |
| bool | hasZ () const |
| QRotationReading * | reading () const |
| void | setHasZ (bool hasZ ) |
| void | hasZChanged (bool hasZ ) |
唯一行為差異是此類正確設置類型。
此類還特徵 reading () 函數返迴 QRotationReading 而不是 QSensorReading .
有關傳感器如何工作的細節,見 QRotationReading .

[read-only]
hasZ
: const
bool
This property holds a value indicating if the z angle is available.
Returns true if z is available. Returns false if z is not available.
訪問函數:
| bool | hasZ () const |
通知程序信號:
| void | hasZChanged (bool hasZ ) |
[explicit]
QRotationSensor::
QRotationSensor
(
QObject
*
parent
= nullptr)
構造傳感器作為子級對於 parent .
[virtual noexcept]
QRotationSensor::
~QRotationSensor
()
銷毀傳感器。停止傳感器若尚未停止。
返迴用於此傳感器的讀取類。

Sets whether the z angle is available to hasZ . This is to be called from the backend. By default the hasZ property is true, so a backend only has to call this if its rotation sensor can not report z angles.
