- getting started - (Using Ubuntu Linux 7.10)
1) Installed Qt bindings for Ruby

- Running the application
1) From the command line I typed ruby helloworld_qt.rb

#file: helloworld_qt.rb

require 'Qt'

    a = Qt::Application.new( ARGV )

    hello = Qt::PushButton.new( "Hello world!", nil )
    hello.resize( 100, 30 )
 
    Qt::Object::connect( hello, SIGNAL('clicked()'), a, SLOT('quit()') )
 
    a.setMainWidget( hello )
    hello.show()
 
    a.exec()

Source code copied from KDE Tutorial - p1 [kde.org]

- getting started - (Using Ubuntu Linux 7.10)
1) Installed glade-3,libglade2-ruby
2) Executed glade-3

- Within glade-3 -
1) Selected from the glade-3 top menu View -> Palette appearance -> Text beside icons
2) Created a window (Toplevels)
3) Created a button on the window (Control and Display)
3) With button selected, from the properties panel I selected the Signals tab and chose 'clicked', then for the Handler -> on_button1_clicked and pressed enter.
4) With window select, from the properties panel I select the Signals tab and chose GtkWidget->delete-event, then for the Handler I typed on_quit and pressed enter.

- Generating and editing the code

-- From the command line -
1) Typed ruby-glade-create-template helloworld3.glade > helloworld3.rb

-- From the file helloworld3.rb - (see helloworld3.rb and how it relates to helloworld3.glade)
1) Implemented the initialise window routine
2) Implemented the button event handler

- Running the application
1) From the command line I typed ruby helloworld3.rb
2) stretched the window to a comfortable dimension.
3) clicked the button and observed the Window title change to 'Hello World!'

==================
Now it can
- listing running applications
- switching them to foreground/background
- closing/killing apps

# listing
apps = appswitch.application_list(True) # true = include all
                                       # false = no hidden apps 
print apps

# to background and closing
print appswitch.switch_to_bg(u"TODO")
print appswitch.end_app(u"TODO")
