Wt is a C++ library for developing Web applications with an API that is widget-centric and inspired by existing C++ graphical user interface APIs. To the developer, it offers abstraction of Web-specific implementation details, increasing the accessibility and portability. Under the hood, the library uses the latest techniques (HTML5, Ajax, WebSockets) to handle user events and update the Web page.
Arg_parser is an argument parser that follows POSIX and GNU conventions for command line arguments. There exist C++ and C versions of Arg_parser. The C++ version is implemented as a C++ class, while the C version is implemented as a single struct plus associated functions. Both are simpler, easier to use, and safer than 'getopt_long'. The C++ version of Arg_parser can also parse options from configuration files.
U++ is a C++ cross-platform rapid application development suite focused on programmers' productivity without sacrificing runtime performance. Based on strictly deterministic design, it provides a viable alternative to garbage-collected platforms, even for business logic oriented problems.
The Crow Designer is a visual editor for building graphical user interfaces. Interfaces are saved in files of the GuiXml format and may be involved in applications by means of the GuiLoader library. During editing, the following instruments are available to a user: a palette of GUI controls, an object tree, an editor canvas, and a hierarchical property explorer. The property explorer allows you to work with nested objects and arrays as well as with several selected objects simultaneously. The designer uses widgets of the GTK+ library as a GUI control kit.
