Constructor Details

#initialize ⇒ MyStateObj

Instance Method Details

#onEnd ⇒ Object

This method is called right after our state object looses ownership of the window. The window is automatically reset, but if you modified anything other than the window, this is where you should clean it up.

def onEnd
  puts "MyStateObj terminated."
end

#onStart ⇒ Object

This method is called right after our state object gains ownership over the window. Now we can perform operations that modify the window.

  #A textbox:
  $textbox = GGLib::TextBox.new("textbox1", 242, 100, 12, GGLib::Themes::Windows)
