QSensorGestureRecognizer

The QSensorGestureRecognizer class is the base class for a sensor gesture recognizer. More…

Synopsis

• def createBackend ()

• def gestureSignals ()

• def startBackend ()

• def stopBackend ()

Detailed Description

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.

class PySide2.QtSensors.QSensorGestureRecognizer([parent=Q_NULLPTR])

param parent:

PySide2.QtCore.QObject

Constructs the QSensorGestureRecognizer with parent as parent.

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()

Calls create() if the recognizer is valid.

PySide2.QtSensors.QSensorGestureRecognizer.detected(arg__1)

Parameters:

arg__1 – str

PySide2.QtSensors.QSensorGestureRecognizer.gestureSignals()

Return type:

list of strings

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()

Return type:

str

Returns the identifier for this recognizer.

PySide2.QtSensors.QSensorGestureRecognizer.isActive()

Return type:

bool

Returns true if this recognizer is active, otherwise false.

PySide2.QtSensors.QSensorGestureRecognizer.start()

Return type:

bool

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

PySide2.QtSensors.QSensorGestureRecognizer.startBackend()

Calls 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()

Return type:

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()

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