Projects

GTK+

GTK+ is a multi-platform toolkit for creating graphical user interfaces. Offering a complete set of widgets, GTK+ is suitable for projects ranging from small one-off projects to complete application suites. GTK+ has been designed from the ground up to support a range of languages, not only C/C++. ... [More] Using GTK+ from languages such as Perl and Python (especially in combination with the Glade GUI builder) provides an effective method of rapid application development. [Less]

Qt 4

Qt is a cross-platform application and UI framework. Using Qt, you can write applications once and deploy them across many desktop and embedded operating systems without rewriting the source code.

Vaadin

Vaadin is a web application framework for Rich Internet Applications (RIA). In contrast to Javascript libraries and browser-plugin based solutions it features a server-side architecture, which means that the majority of the logic runs on the servers. Ajax technology is used at the browser-side to ... [More] ensure a rich and interactive user experience. Vaadin is a big collection of UI components. There are server-side components like Button, Table, Tree that you use to compose the application user interface. The components use events, listeners and data binding to communicate with each other and the business logic. The component based architecture together with the data binding features help you to build applications that are easily modularized and refactored as needed. [Less]

wxWidgets

wxWidgets lets developers create applications for Win32, Mac OS X, GTK+, X11, Motif, WinCE, and more using one codebase. It can be used from languages such as C++, Python, Perl, and C#/.NET. Unlike other cross-platform toolkits, wxWidgets applications look and feel native. This is because wxWidgets ... [More] uses the platform's own native controls rather than emulating them. [Less]

wxPython

wxPython is a Python extension module that wraps the wxWidgets cross-platform GUI library and provides an alternative to Tkinter and PythonWin. It attempts to mirror the class hierarchy of wxWidgets as closely as possible and is very versatile. It can be used to create standalone GUI applications or ... [More] can be used in situations in which Python is embedded in a wxWidgets C++ application as an internal scripting or macro language. The currently supported GUIs are Win32, GTK/X-Windows, and Mac OS X. NOTE: Up until 2007 the wxPython source was located in the wxWidgets repository. See that project here on ohloh for more history details. [Less]

Crazy Eddie's GUI System

A free library providing windowing and widgets for graphics APIs / engines where such functionality is not natively available, or severely lacking. The library is object orientated, written in C++, and targeted at games developers who should be spending their time creating great games, not building GUI sub-systems!

qooxdoo

qooxdoo is a universal JavaScript framework that enables you to create applications for a wide range of platforms. With its object-oriented programming model you build rich, interactive applications (RIAs), native-like apps for mobile devices, light-weight traditional web applications or even ... [More] applications to run outside the browser. You leverage its integrated tool chain to develop and deploy applications of any scale, while taking advantage of modern web technologies like HTML5 and CSS3, its comprehensive feature set and a state-of-the-art GUI toolkit. qooxdoo is open source under liberal licenses, led by the world's largest web host 1&1, with a vibrant community.

Qt 5

Qt is a cross-platform application and UI framework. Using Qt, you can write applications once and deploy them across many desktop and embedded operating systems without rewriting the source code.

gtkmm

gtkmm is the official C++ interface for the popular GUI library GTK+. Highlights include typesafe callbacks, and a comprehensive set of widgets that are easily extensible via inheritance. You can create user interfaces either in code or with the Glade User Interface designer, using libglademm. ... [More] There's extensive documentation, including API reference and a tutorial. [Less]

Fast Light Tool Kit

FLTK (pronounced "fulltick") is a cross-platform C++ GUI toolkit for UNIX/Linux (X11), Microsoft Windows, and Mac OS X. It provides modern GUI functionality without the bloat, and supports 3D graphics via OpenGL and its built-in GLUT emulation. FLTK is designed to be small and modular ... [More] enough to be statically linked, and also works fine as a shared library. It also includes an excellent UI builder called FLUID that can be used to create applications in minutes. [Less]
