The chapters in this book are meant to be fairly independent, but as usual, the ordering reflects a progression from basic concepts to more advanced ones, so the first few chapters at least should be read consecutively for best effect.
Complete programs illustrating concepts in many of the chapters can be found in the accompanying CD-ROM, along with wxWindows itself and lots of extra, cool stuff.
We all hope that you enjoy reading this book and, most importantly, have fun using wxWindows to build great-looking, multiplatform applications!
