The Slider control allows the user to select a numeric value from a predetermined range by dragging the mouse. Note that the similar ScrollBar control is used for scrolling rather than selecting numeric values. Familiar examples include difficulty settings in games and brightness settings in image editors.

The value of a Slider is determined by the position of the handle along its length. The value increases from the Min Value up to the Max Value in proportion to the distance the handle is dragged. The default behaviour is for the slider to increase from left to right but it is also possible to reverse this behavior using the Direction property. You can also set the slider to increase vertically by selecting Bottom To Top or Top To Bottom for the Direction property.
The slider has a single event called On Value Changed that responds as the user drags the handle. The current numeric value of the slider is passed to the function as a
float parameter. Typical use cases include:
