Introduction

The slider widget is almost like a progress bar that the user can manipulate. The slider gives the user a handle that can be dragged along a plane in order to produce the desired value. This is especially useful in working with form values. The slider widget, by default, has useful options such as the ability to change orientation and letting the user select a value range. In this chapter, we'll look at some of the various ways we can tweak the slider widget by adding new options, or by attaching even handler functions. We'll also look at some visual tweaks, and how slider instances can communicate with one another.
