wxWidgets 3.2.11 and 3.3.3 Released

Posted on July 07, 2026

Making releases in both stable 3.2 and latest 3.3 series simultaneously seems to have worked well the last time, so we are doing it again today with the release of the latest stable 3.2.11 and the latest development 3.3.3 versions of wxWidgets. As before, 3.3.3 contains all the changes from 3.2.11 as well as the additional improvements not present in 3.2 series, such as further improvements to dark mode support in wxMSW, including implementing it for message dialogs and support for switching between light and dark modes during run-time.

Both releases can be downloaded from GitHub, please follow these links to download archives with the library sources and documentation as well as binaries for the selected Windows compilers such as Microsoft Visual C++ and MinGW-w64: for 3.2.11 release and for 3.3.3 one. Online documentation has also been updated and can be accessed at 3.2.11 documentation home and 3.3.3 respectively.

If you are new to wxWidgets, you may find the installation guide a good starting point. If you are upgrading to 3.3.3 from a previous version, please make sure to check the change log and, especially, the INCOMPATIBLE CHANGES section there.

Changes since previous releases

3.2.11 includes an unusually huge amount of bug fixes for possible security problems, probably prompted by the increasing use of LLMs for finding them and also helped by the addition of extra fuzzers. Upgrading to this version is strongly recommended if you use any of the functions or classes mentioned below in untrusted contexts:

• Fix multiple buffer overflows in wxBMPHandler: when loading malformed BMP files with invalid RLE data (#26496), invalid palette for 8bpp BMPs (#26438), invalid 4bpp BMPs (#26511).

• Implement C++20 <=> operator for wxString (#26306).
• Add support for private fonts to wxQt (#26403).
• Support building wxOSX under macOS 27 (#26578).

And, finally, some bug fixes which don’t apply to the stable branch:

• Improve wxTarInputStream robustness (#26607).
• Treat truncated reads as errors in wxDataInputStream (#26600).
• Improve wxAUI behaviour on DPI changes in wxMSW (#26075).

wxDart 0.9.2 released

Posted on April 06, 2026

Version 0.9.2 of wxDart has been released.

Dart is a programming language developed by Google. It uses static typing and can be compiled to an executable binary or to JavaScript or WebAssembly to run in a web browser.

wxDart consists of two separate libraries which offer the same API and can be used independently.

• wxDart Flutter uses the Flutter library as its backend and is written in pure Dart.
• wxDart Native provides Dart bindings to the wxWidgets C++ GUI library.

wxDart Flutter has been written from the ground up and does not depend on any C++ or C code. It uses the wxWidgets API, adding many desktop features to Flutter. Apps compiled with wxDart Flutter run almost anywhere (including Android and iOS), but it mainly targets the web.

Like wxWidgets itself, wxDart Native mainly targets the classical desktop environments and offers native look and feel.

Check out the Fireworks demo written with wxDart Flutter, compiled to WebAssembly, and see how it uses wxWidgets API in its source code.

wxDart and its documentation are hosted on pub.dev here.

wxWidgets Book Examples Now Available on GitHub

Posted on March 05, 2025

A comprehensive collection of wxWidgets example applications is now available to the community. These applications were originally developed as supplementary material for the Polish book Cross-Platform Programming with C++ and wxWidgets 3 and are now publicly accessible on GitHub in the dedicated repository All example applications are released under the wxWidgets License.

Repository Contents

The repository contains more than 25 example applications, showcasing various wxWidgets functionalities. These include, among others:

• User interface components and custom controls
• File handling, logging, and system operations
• Networking (HTTP, FTP, and Socket communication)
• Multithreading
• OpenGL and 3D graphics
• Developing a custom code editor with wxScintilla

Additionally, some projects demonstrate more advanced features, making them useful for both beginners and experienced developers looking to integrate wxWidgets into their applications.

All the examples were tested on:

• Windows 11 (Visual Studio 2022, wxWidgets 3.3.x)
• Linux Mint 22 (wxWidgets 3.2.6)

Each project includes configuration files for Visual Studio, Code::Blocks, and Makefile, ensuring compatibility across different development environments.

All examples have been fully translated into English to support a global audience of developers.

All projects have been re-tested, updated, and adapted to the latest versions of wxWidgets and C++20, ensuring modern compatibility and performance.

The repository also includes the upgrade_wxwidgets.py script, which facilitates both upgrading and adapting projects to any version of the wxWidgets library.

This resource provides an excellent starting point for developers interested in exploring wxWidgets through working examples. Users are encouraged to review the code and adapt it to their own projects.

Posted on May 18, 2024

It’s time! wxRuby3 has reached its 1.0.0 stable release.

This release targets the wxWidgets 3.2.5 release by default, which contains (among many others) quite some fixes which came from the development of wxRuby3, and can be installed from RubyGems or downloaded from Github.

This release is the result of about 1.5 years of development, starting at the abandoned remains of wxRuby2, taking a page out of the wxPython Phoenix book and ending with this release.

wxRuby3 is a cross-platform GUI library for Ruby, based on the mature wxWidgets GUI toolkit for C++. It uses native widgets wherever possible, providing the correct look, feel and behavior to GUI applications on Windows, macOS and Linux/GTK. wxRuby aims to provide a comprehensive solution to developing professional-standard desktop applications in Ruby. wxRuby3 also provides extensive usage documentation at its Wiki as well as a complete API reference.

What has changed in this release?

• improved documentation
• support building against wxWidgets GIT master version
• improved stability
• add Wx::Overlay and Wx::DCOverlay
• add 2D affine transformation support
• add Wx::GraphicsRenderer
• various DC support improvements
• add large 2D drawing sample

Full Changelog: https://github.com/mcorino/wxRuby3/compare/v0.9.8…v1.0.0

How to install?

gem install wxruby3

See the INSTALL documentation for more details. Binary packages for major platforms are available as release assets on Github.

Where can I learn more?

Usage Documentation: see the Wiki

API Documentation: see here

Source code: Github

Rubygems: wxRuby3

Where can I provide feedback?

Report problems, bugs, instructions using Github Issues.

Start discussions, submit ideas, feature requests etc. using Github Discussion.

Credits

Thanks go to the dedicated wxWidgets team for providing such a fantastic GUI library to build wxRuby3 on as well as to the wxPython Phoenix team for providing the idea of code generation from the wxWidgets interface docs.

Modern Icon Sets wxArtProvider Released

Posted on November 21, 2023

perazz has released wxMaterialDesignArtProvider, a custom wxArtProvider class providing SVG-based icons from the Material Design, SimpleIcons, FontAwesome and FluentUI system datasets. All these datasets come with permissive licenses (MIT, CC BY 4.0, CC0 1.0, Apache 2.0) that should make it easy to embed it in new and existing projects.

All SVG icons are hardcoded into headers such that no external files are needed to build the art provider class. Each dataset belongs to a custom client (so that filled/outline versions can be used for hovering effects) and color customization is provided via a simple regex-based extension.

Hopefully this can be useful to people who want to make their existing wxWidgets applications access modern icon sets with limited effort.
