--  <description>
--  The Gtk.Button.Gtk_Button widget is generally used to trigger a callback
--  function that is called when the button is pressed. The various signals and
--  how to use them are outlined below.
--
--  The Gtk.Button.Gtk_Button widget can hold any valid child widget. That is,
--  it can hold almost any other standard Gtk.Widget.Gtk_Widget. The most
--  commonly used child is the Gtk.Label.Gtk_Label.
