BOOPSI (Basic Object Oriented Programming System for Intuition) is an object-oriented programming system for AmigaOS. It extends the AmigaOS windowing environment (Intuition) with an object-oriented subsystem allowing a hierarchy of object classes in which every class defines a single GUI widget or interface event. [1]
BOOPSI made it easier for developers to create their own system of widgets and create standardized graphical user interfaces. Magic User Interface and ReAction are examples of complete widget toolkits built on BOOPSI. Both toolkits have become popular with Amiga software programmers to generate and maintain graphical user interfaces.
The object-oriented design brings advantages such as straightforward coupling of objects with other objects. For example, a programmer may link a numerical input field and a sliding control, where if the user adjusts the sliding control the numerical value in the input field changes automatically. [2]
BOOPSI was officially introduced with AmigaOS 2.0 and was further extended in later releases. [3]
The history of the graphical user interface, understood as the use of graphic icons and a pointing device to control a computer, covers a five-decade span of incremental refinements, built on some constant core principles. Several vendors have created their own windowing systems based on independent code, but with basic elements in common that define the WIMP "window, icon, menu and pointing device" paradigm.
In computing, a windowing system is a software suite that manages separately different parts of display screens. It is a type of graphical user interface (GUI) which implements the WIMP paradigm for a user interface.
Carl Sassenrath is an architect of operating systems and computer languages. He brought multitasking to personal computers in 1985 with the creation of the Amiga Computer operating system kernel, and he is the designer of the REBOL computer language, REBOL/IOS collaboration environment, the Safeworlds AltME private messaging system, and other products. Carl is currently a Principal Engineer at Roku, Inc.
In software design, the look and feel of a graphical user interface comprises aspects of its design, including elements such as colors, shapes, layout, and typefaces, as well as the behavior of dynamic elements such as buttons, boxes, and menus. The term can also refer to aspects of a non-graphical user interface, as well as to aspects of an API – mostly to parts of an API that are not related to its functional properties. The term is used in reference to both software and websites.
The Java Foundation Classes (JFC) are a graphical framework for building portable Java-based graphical user interfaces (GUIs). JFC consists of the Abstract Window Toolkit (AWT), Swing and Java 2D. Together, they provide a consistent user interface for Java programs, regardless of whether the underlying user interface system is Windows, macOS or Linux.
A graphical widget in a graphical user interface is an element of interaction, such as a button or a scroll bar. Controls are software components that a computer user interacts with through direct manipulation to read or edit information about an application. User interface libraries such as Windows Presentation Foundation, Qt, GTK, and Cocoa, contain a collection of controls and the logic to render these.
A window manager is system software that controls the placement and appearance of windows within a windowing system in a graphical user interface. Most window managers are designed to help provide a desktop environment. They work in conjunction with the underlying graphical system that provides required functionality—support for graphics hardware, pointing devices, and a keyboard—and are often written and created using a widget toolkit.
X Toolkit Intrinsics is a library that implements an API to facilitate the development of programs with a graphical user interface (GUI) for the X Window System. It can be used in the C language. Design took place late 1980s to early 1990s.
The Magic User Interface is an object-oriented system by Stefan Stuntz to generate and maintain graphical user interfaces. With the aid of a preferences program, the user of an application has the ability to customize the system according to personal taste.
SunView is a discontinued user interface toolkit and windowing system from Sun Microsystems, launched in 1985, and included as part of its Unix implementation, starting with SunOS Release 3.0. Sun had introduced support in 1983 for a window-based environment known as the Sun Window System, providing the Sunwindows window manager and Suntools user interface toolkit.
In computing, ioctl
is a system call for device-specific input/output operations and other operations which cannot be expressed by regular file semantics. It takes a parameter specifying a request code; the effect of a call depends completely on the request code. Request codes are often device-specific. For instance, a CD-ROM device driver which can instruct a physical device to eject a disc would provide an ioctl
request code to do so. Device-independent request codes are sometimes used to give userspace access to kernel functions which are only used by core system software or still under development.
Workbench is the desktop environment and graphical file manager of AmigaOS developed by Commodore International for their Amiga line of computers. Workbench provides the user with a graphical interface to work with file systems and launch applications. It uses a workbench metaphor for representing file system organisation.
Intuition is the native windowing system and user interface (UI) engine of AmigaOS. It was developed almost entirely by RJ Mical. Intuition should not be confused with Workbench, the AmigaOS desktop environment and spatial file manager, which relies on Intuition for handling windows and input events. Workbench uses Intuition to produce displays and AmigaDOS to interact with filing system: AmigaDOS is built on Exec.
Zune is an object-oriented GUI toolkit which is part of the AROS project and nearly a clone, at both an API and look-and-feel level, of Magic User Interface (MUI), a well-known Amiga shareware product by Stefan Stuntz.
ReAction GUI is the widget toolkit engine that is used in AmigaOS 3.2–4.1.
AmigaOS is a family of proprietary native operating systems of the Amiga and AmigaOne personal computers. It was developed first by Commodore International and introduced with the launch of the first Amiga, the Amiga 1000, in 1985. Early versions of AmigaOS required the Motorola 68000 series of 16-bit and 32-bit microprocessors. Later versions were developed by Haage & Partner and then Hyperion Entertainment. A PowerPC microprocessor is required for the most recent release, AmigaOS 4.
A software widget is a relatively simple and easy-to-use software application or component made for one or more different software platforms.
In programming, a tag is an argument to a subroutine that determines other arguments passed to it, which is used as a way to pass indefinite number of tagged parameters to the subroutine; notably, tags are used for a number of system calls in AmigaOS v2.0 and onwards.
