[incr Widgets] An Object-Oriented Mega-Widget Set

The introduction of [incr Tcl] and [incr Tk] allows an object oriented approach to Tk widget construction. "Mega-widgets" developed in these extensions seamlessly expand the Tk base widget set. Each of these object-oriented widgets may themselves be extended, using either inheritance or composition. This paper presents one such general purpose hierarchy called [incr Widgets] which maintains the Motif look-and-feel and establishes several new concepts, including extensible child sites and flexible large scale component configuration.
