# 16.2 `Tix` -- Extension widgets for Tk

The `Tix` (Tk Interface Extension) module provides an additional rich set of widgets. Although the standard Tk library has many useful widgets, they are far from complete. The `Tix` library provides most of the commonly needed widgets that are missing from standard Tk: `HList`, `ComboBox`, `Control` (a.k.a. SpinBox) and an assortment of scrollable widgets. `Tix` also includes many more widgets that are generally useful in a wide range of applications: `NoteBook`, `FileEntry`, `PanedWindow`, etc; there are more than 40 of them.

With all these new widgets, you can introduce new interaction techniques into applications, creating more useful and more intuitive user interfaces. You can design your application by choosing the most appropriate widgets to match the special needs of your application and users.
