Menginstall Ruby dengan menggunakan kode dibawah ini ketik di console $> 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

vbox.pack_start_defaults(btt) end window.add(vbox) window.show_all Gtk.main gambar tampak seperti ini:

# 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('changecurrentpage') { another_tab } nb.append_page(note1, label1) nb.append_page(note2, label2) nb.append_page(button, label3) window.add(nb) window.show_all Gtk.main



CATATAN PENTING: Instalasi Ruby dan Ruby/GTK Mencoba Bahasa Pemrograman Ruby di Linux menggunakan Ubuntu. Ruby/GTK in. Jangan lupa untuk menginstall bahasa pemrograman Ruby terlebih dahulu: $> 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
