This is sort of out of the scope of this particular blog, but I thought I'd pass along the news that we just released another open-source library for wxWidgets users. This one is called wxWebConnect and it's a library for wxWidgets that enables developers to quickly integrate advanced web browser capabilities.
Basically, it wraps up functionality exposed by the Mozilla Foundation's Gecko engine (XULRunner) into a set of user-friendly classes to: embed browser controls, search web content, print web pages, interact with the DOM, implement custom content handling for different MIME types, issue POST calls using the current browser state, etc. Notably, with this library you can also embed all of your favorite Firefox browser plug-ins into your application. We've also gone out of our way to make sure that getting a browser control up and running in your application is as easy as possible.
More information can be found at the wxWebConnect project page. Also, feel free to view some screenshots and a short video demonstration too. If you're a wxWidgets developer, give it a whirl and let us know what you think.
