Detailed Description

Property Documentation

acceleration : float

Specifies the rate at which the axis value changes when a button is held

Access functions:

float acceleration() const
void setAcceleration(float acceleration)

Notifier signal:

void accelerationChanged(float acceleration)

buttons : QVector<int>

Specifies the buttons which control the axis

Access functions:

QVector<int> buttons() const
void setButtons(const QVector<int> &buttons)

Notifier signal:

void buttonsChanged(const QVector<int> &buttons)

deceleration : float

Specifies the rate at which the axis value returns to normal when a button is released

Access functions:

float deceleration() const
void setDeceleration(float deceleration)

Notifier signal:

void decelerationChanged(float deceleration)

scale : float

Specifies how the axis output value is scaled. No scaling is applied by default so it defaults to 1.

Access functions:

float scale() const
void setScale(float scale)

Notifier signal:

void scaleChanged(float scale)
