The Motif Reference Manual is a complete programmer's reference for the Motif toolkit from the Open Software Foundation (OSF). Motif has become the standard user interface for X Window System applications, and the Motif toolkit makes it easy for programmers to build applications that conform with the Motif "look and feel."Dan Heller's Motif Programming Manual has long been considered the most authoritative and insightful work on Motif. Now, with the addition of this companion reference manual, programmers can dispense completely with the original OSF documentation. In addi- tion to covering the entire Motif toolkit, this book also covers OSF's "User Interface Language" or UIL, and the Motif Resource Manager (MRM) functions used to tie together applications with user interfaces defined in UIL.Contents include: Reference pages for all of the Motif functions and macros. Reference pages for the widget classes defined by the Motif toolkit and the X Toolkit Intrinsics. Reference pages for the Motif Resource Manager (Mrm) functions that are used in conjunction with UIL. Reference pages for the Motif clients: mwm, uil, and xmbind. Reference pages that describe the file format of a User Interface Language module. Reference pages for the data types supported by UIL. Reference pages for the User Interface Language functions. A permuted index and a regular index. A number of appendices and quick reference aids including a list of new functions, widget classes, and widget resources in Motif 1.2. This book is designed to be used with Volume 6A, Motif Programming Manual, which describes how to build applications using the Motif toolkit and provides a complete tutorial with programming examples. Both of the books are an integral part of the X Window System series from O'Reilly & Associates, Inc.
