Xojo Windows Declare Version 2.3 has just been finished with more examples, more constants, more data, more explanations, updates from ANSI to Unicode, all Windows 10 compatible, both 32-bit and 64-bit compatible, and updated to Xojo 2017 r2.1. Version 1.x of the Declares book has been impressive and has had many updates for programmers. With the release of Xojo 64-bit debugger coming soon, the declares also needed updating.
Xojo provides a RAD (Rapid Application Development) environment because it protects the user from the Operating System. Xojo has many helpful functions, and declares add to this existing toolbox.
Tapping into the Operating System directly with Declares opens up almost all of the options available for a program - but you are also out of the protection of the safe IDE (Integrated Development Environment) of Xojo. With the ability to change anything with the program or operating system, improper code also provides the ability of a crash. This is written for intermediate and advanced programmers of Xojo.
Thanks to Julian Samphire for work on the 64-bit version of the ChooseColor example and for his comprehensive list of Xojo Data Type Conversions.
All examples have been converted to both 32-bit and 64-bit versions.This book is Version 2.3 (September 2017).
There are many impressive games that have been created with OpenGL, such as Doom3, Counter-Strike, various Medal of Honor, Need for Speed and many others. This book will provide you with the basics to start your own OpenGL core projects on Xojo. Watch the video clips below!
OpenGL is one of the few standards for creating a powerful software interface. There is a great deal of reusable code and material on the internet that can be adapted to Xojo. Another resource with free examples is at Alwyn Bester's website at Xojo3D.com.
This book builds a strong foundation on programming graphics. This is an advanced graphics book and it is highly recommended to understand the Xojo programming language first. An intermediate book called "I Wish I Knew How to... Program the Canvas Control with Xojo Desktop" is a good book to study and understand before learning OpenGL. Examples in this book have been created and tested on Windows 10 and OSX El Capitan operating systems. This book is focused on 32-bit programming. Much of the code works with a timer to provide smooth graphics and animation. Below are a few video's of examples that are included in this book. These examples are currently 32-bit.
