特性文档编制

acceleration : float

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

访问函数:

float acceleration () const
void setAcceleration (float acceleration )

通知程序信号:

void accelerationChanged (float acceleration )

buttons : QVector < int >

Specifies the buttons which control the axis

访问函数:

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

通知程序信号:

void buttonsChanged (const QVector<int> & buttons )

deceleration : float

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

访问函数:

float deceleration () const
void setDeceleration (float deceleration )

通知程序信号:

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.

访问函数:

float scale () const
void setScale (float scale )

通知程序信号:

void scaleChanged (float scale )
