Ruby bindings for the Wt web development toolkit, which
allow you to write widget based web applications wired up
with 'signals' and 'slots' in a very similar manner to a
desktop toolkit such as Qt. The Wt::Ruby bindings runtime is
derived from the well proven QtRuby code, and so it could be
described as a 'QtRuby for web programming'.

Hello World with quit button:

#!/usr/bin/env ruby
require 'wt'

class HelloApplication < Wt::WApplication
def initialize(env)
super(env)
root.addWidget(Wt::WText.new("<h1>Hello, World!</h1>"))
button = Wt::WPushButton.new("Quit", root)
button.clicked.connect(SLOT(self, :quit))
end
end

Wt::WRun(ARGV) do |env|
HelloApplication.new(env)
end

Note that this forms a complete web server that can be run
from the command line as follows:


$ ./hello.rb --docroot . --http-address localhost
--http-port 3000

To deploy the same code via FCGI running under a web server
such as Apache, you just need to change the environment
variable WT_ENV from ‘development’ (or unset) to
‘production’.

Installed wtruby without trouble, but got the following error when running
the Hello World script you included in the annoucement

Ah that's a but in Wt 2.99.0 that I reported on the witty-
interest@lists.sourceforge.net mailing list. The new
WAbstractTableModel class has been left out of the build and you need
to patch wt/src/CMakeLists.txt to include it:
