$> sudo apt-get install ruby-full libruby libruby-extras ruby1.8-dev

Untuk menginstall paket-paket Ruby-GNOME2 di Ubuntu Linux cukup dengan mengetikan perintah:

$> sudo apt-get install ruby-gnome2

#!/usr/bin/env ruby

require 'gtk2'

window = Gtk::Window.new

window.border_width = 10

window.set_size_request(150, 1)

window.title = "Vd. Boxes"

window.signal_connect('delete_event') { false }

window.signal_connect('destroy') { Gtk.main_quit }

labels = %w[Andrew Joe Samantha Jonatan]

# homogeneous, spacing

vbox = Gtk::VBox.new(false, 0)

labels.each do |name|

btt = Gtk::Button.new(name)

btt.signal_connect("clicked") {btt.destroy}



3/8

vbox.pack_start_defaults(btt)

end

window.add(vbox)

window.show_allGtk.main

gambar tampak seperti ini:

#!/usr/bin/env ruby

require 'gtk2'

window = Gtk::Window.new

window.border_width = 20

window.set_size_request(150, 1)

window.title = "H Boxes"

window.signal_connect('delete_event') { false }window.signal_connect('destroy') { Gtk.main_quit }

labels = %w[Jakarta Pekalongan Semarang Surabaya]

# homogeneous, spacing

hbox = Gtk::HBox.new(false, 0)

labels.each do |name|

btt = Gtk::Button.new(name)btt.signal_connect("clicked") {btt.destroy}

# child, expand, fill, padding

hbox.pack_start(btt, false, false, 5)

end

window.add(hbox)

window.show_all

Gtk.main

#!/usr/bin/env ruby

require 'gtk2'

window = Gtk::Window.new(Gtk::Window::TOPLEVEL)window.set_title "Panes"window.border_width = 10window.set_size_request(150, 150)window.signal_connect('delete_event') { Gtk.main_quit }

button1 = Gtk::Button.new("Resize")button2 = Gtk::Button.new("Aku")

button1.signal_connect( "clicked" ) { window.destroy }button2.signal_connect( "clicked" ) { window.destroy }

paned = Gtk::VPaned.newpaned.add1(button1)paned.add2(button2)

window.add(paned)


akan menampilkan seperti ini

#!/usr/bin/env rubyrequire 'gtk2'

window = Gtk::Window.newwindow.border_width = 10window.set_size_request(200, 1)window.title = "Expanders"window.signal_connect('delete_event') { false }window.signal_connect('destroy') { Gtk.main_quit }

fixed = Gtk::Fixed.new

expander = Gtk::Expander.new("klick disini")label = Gtk::Label.new("Tampilkan atau sembunyikan ,\nini adalah

pilihan anda")expander.add(label)



6/8

# make the child (label) visibleexpander.expanded = true

window.add(expander)


#!/usr/bin/env rubyrequire 'gtk2'

def another_tab; puts "Switching"; enddef report_press(w); puts "Somebody pressed gumbek (button) w=#{w}";end

window = Gtk::Window.new(Gtk::Window::TOPLEVEL)window.set_title "Notebook with 3 tabs"window.border_width = 10

window.set_size_request(300, 1)# The delete_event is only needed if you plan to# intercept the destroy / quit with a dialog box.## window.signal_connect('delete_event') { false }# Normally you'd catch the destroy signal, however# as the following code shows delete event can do# anything you want also quit for that matter:# window.signal_connect('destroy') { Gtk.main_quit }window.signal_connect('delete_event') { Gtk.main_quit }

nb = Gtk::Notebook.newlabel1 = Gtk::Label.new("1st Pg")label2 = Gtk::Label.new("2st Pg")label3 = Gtk::Label.new("3rd Pg")note1 = Gtk::Label.new("Page 1 .\nCan switch to ...")note2 = Gtk::Label.new(" 2 page.\nSwitch to ...")button = Gtk::Button.new("Gumbek")

# In Ruby Notebook works without {{ signal_connect }}.#

# In Ruby the following doesn't work (Label does not respond to

'clicked'# note1.signal_connect('clicked') { another_tab }# note2.signal_connect('clicked') { another_tab }

# However you can place a button into a notebook and klick away.button.signal_connect( "clicked" ) {|w| report_press(w) }

nb.signal_connect('change current page') { another_tab }

nb.append_page(note1, label1)nb.append_page(note2, label2)

nb.append_page(button, label3)window.add(nb)window.show_allGtk.main
