    /** Called when a slider's touch event is being started */
    fun onStartTacking(slider: T)

    /** Called when a slider's touch event is being stopped */
    fun onStopTacking(slider: T)

    /** Called when the value of the slider changes  */
    fun onValueChanged(slider: T, value: Float, fromUser: Boolean)

    /** Called before draw inactive track . Return true if the interrupt default draw*/
    fun dispatchDrawInactiveTrackBefore(slider: T, canvas: Canvas, trackRect: RectF, yCenter: Float): Boolean
    /** Called after draw inactive track */
    fun drawInactiveTrackAfter(slider: T, canvas: Canvas, trackRect: RectF, yCenter: Float)

    /** Called before draw active track . Return true if the interrupt default draw*/
    fun dispatchDrawTrackBefore(slider: T, canvas: Canvas, trackRect: RectF, yCenter: Float): Boolean
    /** Called after draw active track */
    fun drawTrackAfter(slider: T, canvas: Canvas, trackRect: RectF, yCenter: Float)

    /** Called before draw thumb drawable . Return true if the interrupt default draw*/
    fun dispatchDrawThumbBefore(slider: T, canvas: Canvas, cx: Float, cy: Float): Boolean

    fun drawThumbAfter(slider: T, canvas: Canvas, cx: Float, cy: Float)
