## 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 : QList<int>

Specifies the buttons which control the axis

Access functions:

QList<int> | buttons() const
void | setButtons(const QList<int> &buttons)

Notifier signal:

void | buttonsChanged(const QList<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)
