- Deprecated.
  use `MouseWheelEvent.getDeltaY()` instead

      @Deprecated
      public class MouseWheelVelocity
      extends java.lang.Object

  Encapsulates the direction and velocity of mouse wheel events. Not all combinations of browser and user input devices can generate all combinations of direction or range of velocity information.

    - #### vY

          protected final int vY

      Deprecated.
      Stores the Y-axis velocity.

  - ### Constructor Detail

    - #### MouseWheelVelocity

          public MouseWheelVelocity(Event e)

      Deprecated.
      Construct the higher-level view of the original ONMOUSEWHEEL Event.
      Parameters:
        `e` - the event

  - ### Method Detail

    - #### equals

          public boolean equals(java.lang.Object o)

      Deprecated.
      Overrides:
        `equals` in class `java.lang.Object`

    - #### getDeltaY

          @Deprecated
          public int getDeltaY()

      Deprecated. use `MouseWheelEvent.getDeltaY()` instead
      Returns the change in the mouse wheel position along the Y-axis; positive if the mouse wheel is moving north (toward the top of the screen) or negative if the mouse wheel is moving south (toward the bottom of the screen).

    - #### hashCode

          public int hashCode()

      Deprecated.
      Overrides:
        `hashCode` in class `java.lang.Object`

    - #### isNorth

          @Deprecated
          public boolean isNorth()

      Deprecated. use `MouseWheelEvent.isNorth()` instead
      Convenience method that returns `true` if `getDeltaY()` is a negative value.
      Returns:
        `true` if the velocity includes a component directed toword the top of the screen

    - #### isSouth

          @Deprecated
          public boolean isSouth()

      Deprecated. use `MouseWheelEvent.isSouth()` instead
      Convenience method that returns `true` if `getDeltaY()` is a positive value.
      Returns:
        `true` if the velocity includes a component directed toword the bottom of the screen

    - #### toString

          public java.lang.String toString()

      Deprecated.
      Overrides:
        `toString` in class `java.lang.Object`
