After all you should have a working ruby installation with KDE 4 bindings.
So lets try the a very minimalistic KDE 4 application to get a first impression.
require 'Qt4'
a = Qt::Application.new ARGV w = Qt::PushButton.new( "Hello Ruby" ) Qt::Object.connect( w, SIGNAL( :clicked ), a, SLOT( :quit ) ) w.show a.exec
require 'Qt4'
class CustomApplication < Qt::Application
slots :doSomething
def doSomething puts "Do something else" Qt::Application.instance.quit end
end
a = CustomApplication.new ARGV w = Qt::PushButton.new( "Hello Ruby" ) Qt::Object.connect( w, SIGNAL( :clicked ), a, SLOT( :doSomething ) ) w.show a.exec
require 'Qt4'
a = Qt::Application.new ARGV w = Qt::PushButton.new( "Hello Ruby" ) w.connect( SIGNAL :clicked ) do
puts "Do something else" Qt::Application.instance.quit
end w.show a.exec
require 'Qt4'
a = Qt::Application.new ARGV w = Qt::PushButton.new( "Hello Ruby" ) do
connect( SIGNAL :clicked ) do puts "Do something else" Qt::Application.instance.quit end
end w.show a.exec
