A Tix mega-widget is composed of one or more component
  widgets. The main part of a mega-widget is called the 
root
  widget
, which is usually a frame widget that encompasses all other
  component widgets. The other component widgets are called 
subwidgets.
The root widget has the same name as the the mega-widget itself. In
  the above example, we have a mega-widget called 
.up. It has a
  root widget which is a frame widget and is also called 
.up. Inside .up we have a button subwidget called .up.button.
Similar to variables and methods, component widgets are also
  classified into public and private component widgets. Only public
  widgets may be accessed by the application programmer, via the 
subwidget method (see section 1.3.1) of each widget
  instance.
