X Window programming from scratch (with CD ROM)
Langue : Anglais
Auteur : BROWN
This book shows how to create a graphical user interface and accomplish graphic rendering using the X Window System software. It offers a unique approach to skill development by leading the reader through basic to very advanced concepts. This title provides all of the following: 7 A guide to the Linux operating system for application development At UNIXs inception, the aim was to equip engineers with maximum power to do their job. As one of the fastest growing operating systems, Linux is finding its way onto more and more desktops as the UNIX of choice. This text shows what makes UNIX the workhorse it is by illustrating how to use Linux in an application development environment. 7 Step-by-step instruction to the correct usage and syntax of C language to accomplish critical constructs and programming logic will enforce the critical first step of learning software application development. 7 Comprehensive introduction of the X Window System for interface creation and graphic rendering This text shows how to create a GUI and accomplish graphic rendering using the X Window System software. Specific topics include creating and managing windows, buttons and icons, using colors and fonts, and drawing geometric shapes based on user input. 7 A complete structured project to "learn by doing" As an erector set for computer programming, this text provides illustrated detail of the pieces required to accomplish a professional 2D graphic editor. Following an analysis of the code necessary to move, scale, rotate and cut graphic objects, instructions let the reader to assemble them into a working application.
