To carry out operations on the widget, you define a set of
  procedures called 
methods (to use common object-oriented
  terminology). Each method can be declared as public or private. 
Public methods can be called by the application programmer. For
  example, if the TixArrowButton class supports the public methods
  
invoke and invert, the application programmer can issue
  the commands to call these method for the widget instance 
.up.
  .up invert.up invoke
   In contrast, 
Private methods are of interests only to widget
  writers and cannot be called by application programmers.
