IUP - Portable User Interface

previous page next page

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:

  • Primitives (effective user interaction): dialog, label, button, text, multi-line, list, toggle, canvas, frame, image.
  • Composition (ways to show the elements): hbox, vbox, zbox, fill.
  • Grouping (definition of a common functionality for a group of elements): radio.
  • Menu (related both to menu bars and to pop-up menus): menu, submenu, item, separator.
  • Additional (elements built outside the main library): dial, gauge, matrix, tabs, valuator, OpenGL canvas, color chooser, color browser.
  • Dialogs (useful predefined dialogs): file selection, message, alarm, data input, list selection.

Hence IUP has some advantages over other interface toolkits available:

  • Simplicity: due to the small number of functions and to its attribute mechanism, the learning curve for a new user is often faster.
  • Portability: the same functions are implemented in each one of the platforms, thus assuring the interface system's portability.
  • Customization: the dialog specification language (LED) and the Lua binding (IupLua) are two mechanisms in which it is possible to customize an application for a specific user with a simple-syntax text file.
  • Flexibility: its abstract layout mechanism provides flexibility to dialog creation.
  • Extensibility: the programmer can create new interface elements as needed.

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

Availability

The library is available for several compilers:

  • GCC and CC, in the UNIX environment
  • Visual C++, Borland C++, Watcom C++ and GCC (Cygwin and MingW), in the Windows environment

The library is available for several operating systems:

  • UNIX (SunOS, IRIX, AIX, FreeBSD and Linux) using Motif 2.x (and optionally 1.x)
  • Microsoft Windows 2000/XP/2003

Support

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

  • Check if the reported behavior is not described in the user guide.
  • Check if the reported behavior is not described in the specific control or driver characteristics.
  • Check the History to see if your version is updated.
  • Check the To Do list to see if your problem has already been reported.

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.
