ViewKlass is a C++ framework for developing applications which use the LessTif, OpenMotif or OSF/Motif[TM] user interface toolkits. In particular it provides classes which support the creation of reusable components. This helps to simplify the development of applications using object-oriented techniques. It also provides classes which encapsulate some of the more difficult and tedious aspects of Motif development. These include classes which handle the creation of windows, dialogs and menus.
