A Glade 'Hello World' application

- 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!'
