QtRuby is a binding of the application framework Qt for Ruby. Korundum is an additional set of bindings for KDE which extend QtRuby.

QtRuby is cross-platform, as all the underlying technologies are platform agnostic.

QtRuby hello world

require 'Qt4'

app =

hello ='Hello World!')
hello.resize(200, 30)


The Korundum documentation[1] proposes a more "rubyish" version of this program.

Status and maintenance

Currently, QtRuby is maintained (if at all) as part of Korundum.

A third-party implementation, named "qtbindings" in the Rubygems repository, has been made due to the lack of active development.[4] Stated goals of the project include keeping an up-to-date version of the Qt framework for Ruby, as well as improving compatibility with non-Linux systems.[5] As of December 2013, it supports Ruby 2.0 and 1.9, but not 1.8.
