The IUP Portable User Interface is a computer software development kit that provides a portable, scriptable toolkit to build graphical user interfaces (GUIs) using the programming languages C, Perl, Lua, Nim and Zig , among others. This allows rapid, zero-compile prototyping and refinement of deployable GUI applications.

Contents

IUP's purpose is to allow programs user interface to run in different systems in unmodified form. [1]

It provides this ability by binding Lua with its C/C++ code, or simply writing C to the application programming interface (API). It handles user interface elements by using native controls provided by native APIs, such as Windows API in Windows, GTK+ in Linux, and Motif-LessTif in older Unices. It also provides some custom developed controls using graphics APIs such as CD - Canvas Draw or OpenGL.

Features

IUP's distinguishing features include:

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.

IUP is liberally-licensed for free use, modification, sale, and redistribution under the MIT license. [2]

IUP has been in development at least since the 1.8 version issued in 1998. It was begun in collaboration with Petrobras.

In computing, cross-platform software is computer software that is designed to work in several computing platforms. Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without special preparation, being written in an interpreted language or compiled to portable bytecode for which the interpreters or run-time packages are common or standard components of all supported platforms.

A widget toolkit, widget library, GUI toolkit, or UX library is a library or a collection of libraries containing a set of graphical control elements used to construct the graphical user interface (GUI) of programs.

<span class="mw-page-title-main">Swing (Java)</span> Java-based GUI toolkit

Swing is a GUI widget toolkit for Java. It is part of Oracle's Java Foundation Classes (JFC) – an API for providing a graphical user interface (GUI) for Java programs.

wxWidgets Widget toolkit

wxWidgets is a widget toolkit and tools library for creating graphical user interfaces (GUIs) for cross-platform applications. wxWidgets enables a program's GUI code to compile and run on several computer platforms with minimal or no code changes. A wide choice of compilers and other tools to use with wxWidgets facilitates development of sophisticated applications. wxWidgets supports a comprehensive range of popular operating systems and graphical libraries, both proprietary and free, and is widely deployed in prominent organizations.

<span class="mw-page-title-main">Standard Widget Toolkit</span>

The Standard Widget Toolkit (SWT) is a graphical widget toolkit for use with the Java platform. It was originally developed by Stephen Northover at IBM and is now maintained by the Eclipse Foundation in tandem with the Eclipse IDE. It is an alternative to the Abstract Window Toolkit (AWT) and Swing Java graphical user interface (GUI) toolkits provided by Sun Microsystems as part of the Java Platform, Standard Edition (J2SE).

<span class="mw-page-title-main">FLTK</span>

Fast Light Toolkit is a cross-platform widget library for graphical user interfaces (GUIs), developed by Bill Spitzak and others. Made to accommodate 3D graphics programming, it has an interface to OpenGL, but it is also suitable for general GUI programming.

<span class="mw-page-title-main">Windows Forms</span> Graphical user interface software library

Windows Forms (WinForms) is a free and open-source graphical (GUI) class library included as a part of Microsoft .NET, .NET Framework or Mono Framework, providing a platform to write client applications for desktop, laptop, and tablet PCs. While it is seen as a replacement for the earlier and more complex C++ based Microsoft Foundation Class Library, it does not offer a comparable paradigm and only acts as a platform for the user interface tier in a multi-tier solution.

<span class="mw-page-title-main">Fox toolkit</span>

The FOX toolkit is an open-source, cross-platform widget toolkit, i.e. a library of basic elements for building a graphical user interface (GUI). FOX stands for Free Objects for X.

Graphical user interface builder Software development tool

A graphical user interface builder, also known as GUI designer or sometimes RAD IDE, is a software development tool that simplifies the creation of GUIs by allowing the designer to arrange graphical control elements using a drag-and-drop WYSIWYG editor. Without a GUI builder, a GUI must be built by manually specifying each widget's parameters in source-code, with no visual feedback until the program is run. Such tools usually called the term RAD IDE.

A user interface markup language is a markup language that renders and describes graphical user interfaces and controls. Many of these markup languages are dialects of XML and are dependent upon a pre-existing scripting language engine, usually a JavaScript engine, for rendering of controls and extra scriptability.

<span class="mw-page-title-main">XVT</span>

XVT is a software development environment for building cross-platform GUI applications in C or C++. XVT allows developers to graphically lay out an application's GUI, and provides cross-platform libraries to aid development.

A PIGUI package is a software library that a programmer uses to produce GUI code for multiple computer platforms. The package presents subroutines and/or objects which are independent of the GUIs that the programmer is targeting. For software to qualify as PIGUI it must support several GUIs under at least two different operating systems. The package does not necessarily provide any additional portability features. Native look and feel is a desirable feature, but is not essential for PIGUIs.

A software widget is a relatively simple and easy-to-use software application or component made for one or more different software platforms.

<span class="mw-page-title-main">GTK</span> Free and open-source cross-platform widget toolkit for creating graphical user interfaces

GTK is a free and open-source cross-platform widget toolkit for creating graphical user interfaces (GUIs). It is licensed under the terms of the GNU Lesser General Public License, allowing both free and proprietary software to use it. It is one of the most popular toolkits for the Wayland and X11 windowing systems.

<span class="mw-page-title-main">Abstract Window Toolkit</span> Java-based GUI toolkit

The Abstract Window Toolkit (AWT) is Java's original platform-dependent windowing, graphics, and user-interface widget toolkit, preceding Swing. The AWT is part of the Java Foundation Classes (JFC) — the standard API for providing a graphical user interface (GUI) for a Java program. AWT is also the GUI toolkit for a number of Java ME profiles. For example, Connected Device Configuration profiles require Java runtimes on mobile telephones to support the Abstract Window Toolkit.

Hollywood (programming language) Programming language

Hollywood is a commercially distributed programming language developed by Andreas Falkenhahn which mainly focuses on the creation of multimedia-oriented applications. Hollywood is available for AmigaOS, MorphOS, WarpOS, AROS, Windows, macOS, Linux, Android, and iOS. Hollywood has an inbuilt cross compiler that can automatically save executables for all platforms supported by the software. The generated executables are completely stand-alone and do not have any external dependencies, so they can also be started from a USB flash drive. An optional add-on also allows users to compile projects into APK files.

mpv is free and open-source media player software based on MPlayer, mplayer2 and FFmpeg. It runs on several operating systems, including Unix-like operating systems and Microsoft Windows, along with having an Android port called mpv-android. It is cross-platform, running on ARM, PowerPC, x86/IA-32, x86-64, and MIPS architecture.
