== Slider Class

The Slider class provides the same 3 common contrustors shown in the <<jme3/contributions/tonegodgui/quickstart#,Quick Start Guide>> with the addition of two extra parameters.

*  The orientation of the Slider
*  A boolean flag telling the control whether or not the track should “surround” the thumb.

The additional parameter are appended to the existing parameter list for all 3 constructors, like so:

[source,java]

/**
  * Parameters:
  * Screen screen
  * String UID
  * Vector2f position
  * Slider.Orientation orientation
  * boolean trackSurroundsThumb
  */
Slider slider1 = new Slider(
    screen,
    “SomeID”,
    new Vector2f(15, 15),
    Slider.Orientation.HORIZONTAL,
    true
);
