The purpose of the 
InitWidgetRec method is to initialize the
  variables of the widget instance. For example, the following
  implementation of 
tixArrowButton:InitWidgetRec sets the count variable of each newly created instance to zero.
  proc tixArrowButton:InitWidgetRec {w} {    upvar #0 $w data
    set data(count) 0
}
Earlier, we showed how each widget you create is associated with an
  array of the same name.  Within the methods, you always refer to
  this array through the name 
data -the method then works
  properly in each instance of the widget.
