Cross-Platform GUI Programming with wxWidgets
This book is available from several sources like amazon, informit and others but in my country (Venezuela) there is a limit in a year (400$ a year) for internet buying (using foreing currency as $), and I already reached my limit, because this I only have access to sample chapter, but I found a wonderful thing:
If I do click in downloads there is available the full version of the book in pdf for free, this is great, and I'm going to use it in this way for this year, but the next year (the limit is for each year) I'm going to buy it to support the authors of the book.
Don't worry book is free because it's part of Bruce Perens' Open Source Series:
In this series the electronic versions will be made available at no cost several months after each book's publication.
