Class Slider

  • All Implemented Interfaces:
    ControlAnimation.AnimationFinished, PathAnimation.SetPosition
    public class Slider
extends ScrollBar
    Slider is a simple slider. You can set some properties of the slider, like drawTicks, invertDirection and drawFilledArea; read the javadocs of each for more information. You can change the thumb size by setting the minDragBarSize public field and then call setValues or setMaximum or setMinimum method (value must always be ODD!).

    TotalCross 1.0
