Custom Gestures [RESOLVED]



  • I have some trouble with QGestureRecognizer, i tried to simplfy my problem here is the samplke code ;

    GestureWatcher is a derived class from QGestureRecognizer.

    @
    QGestureRecognizer::Result GestureWatcher::recognize(QGesture *state, QObject *, QEvent *event)
    {
    if (event->type() == QEvent::GraphicsSceneMousePress) {
    return QGestureRecognizer::TriggerGesture;
    }
    else if (event->type() == QEvent::GraphicsSceneMouseRelease) {
    return QGestureRecognizer::FinishGesture;
    }
    return QGestureRecognizer::Ignore;
    }

    ...
    // Register custom gesture recognizer.
    m_gestureType = QGestureRecognizer::registerRecognizer(new GestureWatcher());
    grabGesture(m_gestureType);
    ...

    bool GestureItem::sceneEvent(QEvent *event)
    {
    qDebug() << "event.type" << event->type();
    if (event->type() == QEvent::Gesture) {
    qDebug() << "This is a gesture !!!!";
    return true;
    }
    return QDeclarativeItem::sceneEvent(event);
    }
    @

    Gesture is never catch by sceneEvent i'm getting an error as;

    "QGestureManager::deliverEvent: could not find the target for gesture"

    . Do you have any idea what i'm missing. Thanks.



  • Hey there,

    I found a missing information in documents. You need to set for QGO derived objects hot spot point, otherwise gesture never catch by sceneEvents.
