Programming the OS/2 WARP version 3 GPI

Programmers who work in the OS/2 Presentation Manager environment will appreciate this in-depth guide to fully exploiting the more advanced features of OS/2's GPI. The only guide devoted exclusively to the subject, it does much more than describe how GPI functions work, it actually shows you with numerous examples and a fully fleshed-out application. Written by IBM insiders Steve Knight and Jeffrey Ryan, it offers proven solutions to a wide range of user-interface problems, and detailed, step-by-step guidance to the full range of functions rarely covered in more general books on Presentation Manager. The first book to focus entirely on the advanced features of OS/2's GPI updated for OS/2 WARP Version 3 Covers such important topics as working with graphic primitives, working in different viewing coordinate spaces, metafiles, correlation, and more Helps programmers quickly learn how to use all the features discussed by developing a complete working application (a graphics editor) that they can easily adapt to their own work Extremely well illustrated, includes more than 60 screen shots, line drawings, and tables—all created with the enclosed sample application
