Windows - How to?

I wanted to play with windows, So I built this really basic thing:

Code: [Select]

class Game_Interpreter
  def call_sample
    SceneManager.call(Scene_Sample)
  end
end

class Sample < Window_Base
  def initialize(x, y, width, height)
    super
  end
end

class Scene_Sample < Scene_MenuBase
 
  def start
    super
    create_window
  end
 
  def create_window
    @window = Sample.new(122, 122, 122, 122)
  end
 
end

calling: call_sample will open your window, how ever hitting esc, like on any other window won't close it.....I've seen numerous scripts do this and no one seems to have a dispose method built for their windows. How are they doing it? How are they closing windows when you hit esc?
