The IUP Portable User Interface is a computer
and refinement of deployable GUI applications.IUP's purpose is to allow programs user interface to run in different systems in unmodified form.[2]
It provides this ability by
Features
IUP's distinguishing features include:
- ANSI C API, one of the few plain C-capable toolkits,
- Single API for Windows or Linux,
- Built in support for Lua scripts calling IUP functions (controlled by Lua script),
- Removal of the restriction of class/instance object types, but retaining the prototype Lua-style hierarchy of inheritance.
- An abstract layout model, in which sizes and positions are calculated from horizontal and vertical containers, rather than explicit X and Y coordinates. Coordinate-based layout is also supported with a third container type.
- Small API, on the order of about 100 functions.
- Use of an callbackmechanism. This main loop can be called inside Lua.
- Interface elements are created before they are mapped to the native elements. This is the reverse of the usual situation for assembling GUI elements.
- Available as source or pre-built static or dynamic libraries for a wide variety of compilers, including turnkey example source.
The Lua scripting is done by binding Lua and IUPLua in (at least) a small C program called a host application. This program creates a Lua state, passes the Lua state to IUPLua for initialization, and then opens and executes a Lua script against the Lua state. Or, the entire IUP state can be dynamically loaded via use of a Lua require or package.loadlib of IUPLua.
The script(s) can later be compiled with the Lua compiler if needed.
Support for UTF-8 was added to the Windows target in November 2013 with the release of version 3.9.[3]
