The QtLua library aims to make Qt 4 applications scriptable using the Lua scripting language. It is an alternative to the QtScript module. QtLua does not generate or use generated binding code for Qt. Instead it provides useful C++ wrapper classes to make C++ and Lua objects accessible from both Lua and C++. It takes advantage of the Qt meta object system to expose QObject members to Lua scripts and comes with user manual and examples.
Peggy helps you to create GTK applications that run out-of-the-egg. It offers functions to load resources (like .glade files, images, and locales) from a zipped or unzipped egg. It is a thin layer on top of setuptools and PyGtk. It doesn't do anything very fancy, but it can save you from reading some documentation.
RTK (Ruckus Tool Kit) is a high-performance, Perl-based, dynamic, content-generation system. It provides a nearly transparent bridge between HTML-based code pages and traditional CGI-based systems. It has been designed to automatically take advantage of existing systems, such as basic CGI, Apache's mod_perl, FastCGI, and SpeedyCGI, but does not require such systems for high-performance optimization.
XUIML for Adobe Flex is a framework and markup language to create Adobe Flex user interfaces quickly and without coding a single line of ActionScript. The XUIML terminal connects to any SOAP or RESTful Web service and expects simple UI instructions such as "open window", "add tab panel", or "draw textbox", which are then rendered as Adobe Flex widgets.
libTISCH is a framework for easy development of multi-touch applications. It contains tools for video processing, calibration, gesture recognition and, most importantly, a GUI toolkit with widgets that utilize the multi-touch gestures detected by the lower layers. It runs on Linux, Mac OS X, and Windows.
libkinput is a small, lightweight command line editing library. It was written as a smaller alternative to the readline library. The main goal of the project is to implement a clean, lightweight, and easy to modify readline equivalent for small and medium CLI applications. It is part of ASNlibs.
