## The Racket Graphical Interface Toolkit

Matthew Flatt,
Robert Bruce Findler,
and John Clements

(require racket/gui/base) | package: gui-lib

The racket/gui/base library provides all of the class, interface, and procedure bindings defined in this manual, in addition to the bindings of racket/draw and file/resource.

#lang racket/gui | package: gui-lib

The racket/gui language combines all bindings of the racket language and the racket/gui/base and racket/draw modules.

The racket/gui toolbox is roughly organized into two parts:

- The windowing toolbox, for implementing windows, buttons, menus, text fields, and other controls.

- The editor toolbox, for developing traditional text editors, editors that mix text and graphics, or free-form layout editors (such as a word processor, HTML editor, or icon-based file browser).

Both parts of the toolbox rely extensively on the racket/draw drawing library.
