This guide is aimed at experienced programmers who wish to write their own Motif widgets.
The ideal reader will have as prerequisite some experience writing Intrinsics-based widgets. Failing that, the reader must have at least a general understanding of the X Window System, plus a good grasp of Xlib and Xt. The reader should also understand Motif programming topics such as resources, actions, and keyboard traversal. Finally, the more the reader understands about object-oriented programming, the better.
This guide assumes that the reader is familiar with the American National Standards Institute (ANSI) C programming language or with the C++ programming language.
