QSensorGestureRecognizer ¶

概要 ¶

详细描述 ¶

QSensorGesture recognizer developers should sub-class this to implement their own recognizer.

All sensor gesture recognizers have a detected( QString ) signal. Implementors can use this and send recognizer specific gestures, such as detected(“shake_left”) or implement custom signals such as shakeLeft().

These custom signals will be available in the QSensorGesture object at runtime.

gestureSignals()

class QSensorGestureRecognizer ( [ parent=Q_NULLPTR ] ) ¶

param parent

QObject

构造 QSensorGestureRecognizer with parent 作为父级。

PySide2.QtSensors.QSensorGestureRecognizer. create ( ) ¶

Called by QSensorGesture object constructor to create the recognizers backend.

Implementors would use this to instantiate QSensors and connect signals.

PySide2.QtSensors.QSensorGestureRecognizer. createBackend ( ) ¶

调用 create() if the recognizer is valid.

PySide2.QtSensors.QSensorGestureRecognizer. detected ( arg__1 ) ¶

参数

arg__1 – unicode

PySide2.QtSensors.QSensorGestureRecognizer. gestureSignals ( ) ¶

返回类型

字符串列表

Returns a list of signals that this recognizer supports.

Note that all signals declared will be exported to the QSensorGesture object. If you need to use signals that are not exported, you should use a private class to do so.

PySide2.QtSensors.QSensorGestureRecognizer. id ( ) ¶

返回类型

unicode

Returns the identifier for this recognizer.

PySide2.QtSensors.QSensorGestureRecognizer. isActive ( ) ¶

返回类型

bool

Returns true if this recognizer is active, otherwise false.

PySide2.QtSensors.QSensorGestureRecognizer. start ( ) ¶

返回类型

bool

Called by startDetection() to start this recognizer. Implementors should start the sensors. Returns true if the operation is successful.

PySide2.QtSensors.QSensorGestureRecognizer. startBackend ( ) ¶

调用 start() if the recognizer isn’t already initialized. This is called by the QSensorGesture object, so please use that instead.

startDetection()

PySide2.QtSensors.QSensorGestureRecognizer. stop ( ) ¶

返回类型

bool

Called by stopDetection() to stop this recognizer. Returns true if the call succeeds, otherwise false.

Implementors should stop the sensors.

PySide2.QtSensors.QSensorGestureRecognizer. stopBackend ( ) ¶

调用 stop() if no other clients are using it. This is called by the QSensorGesture object, so please use that instead.
