GUI Toolkits for Ruby

Traditionally, Ruby is a command line tool. Most Ruby commands are entered as text in a terminal and provide output to the user in the text form. Actually, the Ruby interpretor is not bound to any program development environment. Ruby programs can be typed in any editor and there are a lot of libraries to provide Graphical User Interface (GUI). This article discusses various GUI toolkits for Ruby, right from traditional to the most popular toolkits.

Introduction

Standard Inbuilt Toolkit library

Overview

The 'Tk' library is provided along with the standard Ruby distribution. It is well-suited for cross-platform application development. Tk is an open source, platform independent toolkit which can be easily customized and configured. Tk provides a number of widgets commonly needed to develop desktop applications such as button, menu, canvas, text, frame, label etc.

Thirdparty Toolkits

There are a lot number of toolkit libraries for Ruby provided by third-party vendors. Mostly these are wrappers around toolkits written in C and C++. Many of these toolkits may not support cross-platform application development.

Ruby Exclusive Toolkit

Shoes is a library implemented exclusively for Ruby. It is one of the most popular toolkits for Ruby.

Recent libraries associated with the development environment

Recent Ruby implementations have their own GUI facilities provided by toolkits associated with the environment. Some of them are Cocoa for MacRuby and Swing for JRuby.
