An alarm to tell you to go home with ruby and GTK

#!/usr/bin/env ruby

Author : Emad Elsaid (https://github.com/blazeeboy)

require 'gtk2' # gem install gtk2

lets define some constants we need

WORKING_HOURS = 8 # hours
WORKING_SECONDS = WORKING_HOURS * 60 * 60
ALERT = "Your working hours have been ended,\n go out and enjoy your life."

we'll inherit the Gtk window and make our custom behaviour inside it

class WorkEndWindow < Gtk::Window

set some window properties and insert a label with the desired text then link the window destroy event with a method to exit the application

  def initialize
    super

    self.title = ':D'
    self.border_width = 20
    self.window_position = Gtk::Window::POS_CENTER_ALWAYS

    add Gtk::Label.new ALERT
    signal_connect("destroy") { Gtk.main_quit }
    show_all
  end
end

this will wait for you to finish work and then pops up the amazing window that will tell you to go home ^_^ it will create a window then start the Gtk main loop

sleep WORKING_SECONDS
WorkEndWindow.new
Gtk.main```
