Slider

The Slider object is a generic scrollbar control. It produces a numeric value whenever the user moves its thumb, which can be linked to a ScrollCanvas, a game variable or a script.

A slider is composed from two parts: the bar and the thumb (see fig 2). Both of these can be customized with NoveltyML.

Caveats

Visual components (such as Borders, Images) of a Slider will be automatically sized to fill the slider's rectangle unless a specific size is set.

The value of a slider can be linked to a script function, which gets called whenever the thumb is moved. Any function that returns void and takes one int, float or a double will work.
