In my previous posts here and here I showed how to create a simple application which uses Document/View framework. Now I’m going to show more complex example – image viewer with scrolling and selection rectangle. As far as I can see from wxForum, implementation of selection-related functionality is some kind of complex but very useful task. So, let’s start from simple part. The simplest task here is modification of our wxDocument-related class.
June 24th, 2008 -- the wxWidgets team is pleased to announce a new wxWidgets release. wxWidgets is a mature, open source, cross-platform application framework for C++ and other languages. To get wxWidgets, please go to the download page at http://www.wxwidgets.org/downloads/ This is mainly a bug fix release; please see the change log below for details.
This wxJSON release adds support for 64-bits integers on those platforms that have native support for it such as, for example, Windows and GNU/Linux.
You can disable 64-bits integer support if you do not need (or do not want) it. The new version is compatible wih the past: if you do not need 64-bits integers you…
При работе с потоками часто приходится делать кучу однотипных задач: создавать класс, производный от wxThread, реализовывать метод Entry() для этого класса, синхронизацию с главным потоком и т.д.
Eran, автор CodeLite IDE поделился кодом класса JobQueue, который реализует пул потоков и позволяет выполнять задачи в фоновом режиме.
Главный поток получает уведомления таким вот образом:
// in the event table
EVT_COMMAND(wxID_ANY,…
This release adds the 'copy-on-write' feature to the copy ctor and assignment operator of JSON value class.
Note that this new feature only affects the internal representation of JSON values and does not add new features in the class's interface.
Also note that for JSON value objects, COW is not as efficient as expected.

Today we’ll dig a little bit deeper into Document/View framework provided by wxWidgets and will see how to create a simple text editor using this framework.
We’ll take the source code from the previous article of this series and add some modifications. You will see below that modifications are rather simple and take almost no time.
First of all we have to make
wxDocTemplate to handle desired file extensions (in our case it’s TXT).A few weeks ago, working on TIFF viewer software, I realized that many developers, who use wxWidgets in their work, spend their time on implementing the functionality which already exists in wxWidgets library. Such tasks as loading/saving documents, edit/copy/paste functionality, separating the GUI from application’s logic, all of them can be performed in a far…
wxWidgets находится в процессе работы над улучшением документации - мигрирации из текущей системы, основанной на LaTeX, в Doxygen (используя отдельный набор "интерфейсных" заголовков, вместо рабочих заголовков wxWidgets).
Разработчики wxWidgets потратили несколько месяцев на создание скриптов для автоматического преобразования документации, и уже достигли той точки, где скрипты уже не могут помочь. В Документация wxWidgets довольно обширна и…
Сегодня вашему вниманию предлагается статья Cosm'а о том, как собрать и настроить среду разработки Code::Blocks под FreeBSD.
В этой статье я попытаюсь вам объяснить как ставить Code::Blocks в FreeBSD. Code::Blocks это кросплатформенная IDE построена с помощью wxWidgets. В моем случае установка проводилась на FreeBSD-7.0-Release-i386.
JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language independent…
