KDElibs (KDE)

claimed by KDE

The KDE libraries, basis of KDE and used by many open source projects. They are based on Qt, Trolltech's cross-platform toolkit, and run on Linux, BSDs, and other Unices, as well as Microsoft Windows and Mac OS X. Licensed under GNU LGPL, they may be used by open source and proprietary applications.

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!

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.

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]

Ultimate++

Ultimate++ is a C++ cross-platform rapid application development suite. It includes a set of libraries (GUI, SQL, etc..), and an integrated development environment. Rapid development is achieved by the smart and aggressive use of C++ rather than through fancy code generators. In this respect, U++ ... [More] competes with popular scripting languages while preserving C/C++ runtime characteristics. [Less]

jSeamless

jSeamless is a UI abstraction layer for Java to allow developers to write code for any platform and any environment (Web, Desktop, Mobile, etc.) without having to know ahead of time the deployment platform or environment will.

Visual Component Framework

The Visual Component Framework is a cross platform C++ application framework that offers a modern, clean architecture. It is divided into three major libraries. The FoundationKit provides services such as file access, streams, threads, synchronization primitives, and advanced RTTI features. The ... [More] GraphicsKit includes classes for working with both image and vector graphics, and has built in support for the Anti-Grain Graphics library. The ApplicationKit provides GUI controls, use of the Model-View-Control pattern, property and component editors, undo/redo support, drag-and-drop, clipboard services, application resources, and UI metrics and policy managers. Additional "Kits" adding advanced functionality include an HTML kit, Internet kit, JavaScript kit, Network kit, OpenGL kit, and RegEx kit [Less]

LibNUI

libNUI is a hardware accelerated GUI framework that makes it possible to build rich multi-platform applications based on 3D rendered dynamic layouts. Interfaces are built as a composition of widgets and behaviors, and the framework handles positioning, resizing, anchoring, and texture stretching. ... [More] Objects are connected with synchronous events and delegates for mono-threaded communication, or asynchronous notifications and message queues are used for multi-threaded applications. It also supports strings (including Unicode), paths, files, data streams, fonts, threads, critical sections, audio buffer rendering, and more. [Less]
