Overview

IUP is a portable toolkit for building graphical user interfaces. It offers APIs in three basic languages: C, Lua and LED.

Its library contains about 100 functions for creating and manipulating dialogs.

IUP's purpose is to allow a program to run in different systems without changes - the toolkit provides the application portability. Supported systems include: Motif and Microsoft Windows 2000/XP/2003.

IUP uses an abstract layout model based on the boxes-and-glue paradigm from the TEX text editor. This model, combined with the dialog-specification language (LED) or with the Lua binding (IupLua) makes the dialog creation task more flexible and independent from the graphics system's resolution.

Currently available interface elements can be categorized as follows:

Hence IUP has some advantages over other interface toolkits available:

IUP is free software, can be used for public and commercial applications.

Availability

The library is available for several compilers:

The library is available for several operating systems:

Support

The official support mechanism is by e-mail, using iup AT tecgraf.puc-rio.br (replace " AT " by "@"). Before sending your message:

If all these points were checked, you can report your problem. Please specify in your message: function, attribute, callback, platform and compiler.

We host IUP support features at LuaForge. It provides us Tracker, Lists, News, CVS and Files. The IUP page at LuaForge is available at: http://luaforge.net/projects/iup/.

The discussion list is available at: http://lists.luaforge.net/mailman/listinfo/iup-users.
You can also submit Bugs, Feature Requests and Support Requests at: http://luaforge.net/tracker/?group_id=89.
Source code, pre-compiled binaries and samples can be downloaded at: http://luaforge.net/frs/?group_id=89.
The CVS can be browsed at: http://luaforge.net/scm/?group_id=89.

If you want us to develop a specific feature for the toolkit, Tecgraf is available for partnerships and cooperation. Please contact tcg AT tecgraf.puc-rio.br.
