How does the object-oriented approach of Toe fit with Tk widgets?

A fundamental and unavoidable difference exists between Tk widgets and object-oriented design. Tk widgets are structured in a containment hierarchy, whereas OO classes are structured in an inheritance hierarchy. To use a term of art, the impedance between a set of related programmable objects and a set of related graphical widgets can be reduced by design, but not eliminated. The encapsulation of widgets in objects is encouraged anyway, so that introspection services and cross-cutting aspects can be applied to widget-containing objects. See, for example, the Samples section.
