Intuition (Amiga)
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 (OS kernel). Intuition is the internal widget and graphics system. It is not implemented primarily as an application-managed graphics library (as most systems, following Xerox's design, have done), but rather as a separate task that maintains the state of all the standard UI elements independently from the application. This makes it responsive because UI gadgets are live even when the application is busy. The Intuition task is driven by user events through the mouse, keyboard, and other input devices. It also arbitrates collisions of the mouse pointer and icons and con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amiga Workbench 1 0
Amiga is a family of personal computers introduced by Commodore in 1985. The original model is one of a number of mid-1980s computers with 16- or 32-bit processors, 256 KB or more of RAM, mouse-based GUIs, and significantly improved graphics and audio compared to previous 8-bit systems. This includes the Atari ST—released earlier the same year—as well as the Macintosh and Acorn Archimedes. Based on the Motorola 68000 microprocessor, the Amiga differs from its contemporaries through the inclusion of custom hardware to accelerate graphics and sound, including sprites and a blitter, and a pre-emptive multitasking operating system called AmigaOS. The Amiga 1000 was released in July 1985, but production problems kept it from becoming widely available until early 1986. The best-selling model, the Amiga 500, was introduced in 1987 along with the more expandable Amiga 2000. The Amiga 3000 was introduced in 1990, followed by the Amiga 500 Plus, and Amiga 600 in March 1992. Fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magic User Interface
The Magic User Interface (MUI in short) 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. The Magic User Interface was written for AmigaOS and gained popularity amongst both programmers and users. It has been ported to PowerPC processors and adopted as the default GUI toolkit of the MorphOS operating system. The MUI application programmer interface has been cloned by the Zune toolkit used in the AROS Research Operating System. History Creating GUI applications on Amiga was difficult for a very long time, mainly because the programmer got only a minuscule amount of support from the operating system. Beginning with Kickstart 2.0, the gadtools.library was a step in the right direction, however, even using this library to generate complex and flexible interfaces remained difficult and still required a gr ...

Drive Letter
In computer data storage, drive letter assignment is the process of assigning alphabetical identifiers to volume (computing), volumes. Unlike the concept of Unix filesystem, UNIX mount points, where volumes are named and located arbitrarily in a single hierarchical namespace, drive letter assignment allows multiple highest-level namespaces. Drive letter assignment is thus a process of using letters to name the roots of the "forest" representing the file system; each volume holds an independent "tree" (or, for non-hierarchical file systems, an independent list of files). Origin The concept of drive letters, as used today, presumably owes its origins to IBM's VM (operating system), VM family of operating systems, dating back to CP/CMS in 1967 (and its research predecessor CP-40), by way of Digital Research's (DRI) CP/M. The concept evolved through several steps: * CP/CMS uses drive letters to identify ''minidisk (CP/CMS), minidisks'' attached to a user session. A full file referen ...

Semaphore (programming)
In computer science, a semaphore is a variable or abstract data type used to control access to a common resource by multiple threads and avoid critical section problems in a concurrent system such as a multitasking operating system. Semaphores are a type of synchronization primitive. A trivial semaphore is a plain variable that is changed (for example, incremented or decremented, or toggled) depending on programmer-defined conditions. A useful way to think of a semaphore as used in a real-world system is as a record of how many units of a particular resource are available, coupled with operations to adjust that record ''safely'' (i.e., to avoid race conditions) as units are acquired or become free, and, if necessary, wait until a unit of the resource becomes available. Semaphores are a useful tool in the prevention of race conditions; however, their use is not a guarantee that a program is free from these problems. Semaphores which allow an arbitrary resource count are calle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zune (GUI Toolkit)
Zune is an object-oriented GUI toolkit which is part of the AROS (AROS Research Operating System) 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. Zune is based on the BOOPSI system, the framework inherited from AmigaOS for object-oriented programming in C. Zune classes don't derive from existing BOOPSI gadget classes; instead, the Notify class (base class of the Zune hierarchy) derives from the BOOPSI root class. Wanderer Wanderer is the whole desktop and not only window manager user interface that is based on Zune widget toolkit.''"Wanderer is the whole desktop, not just a filemanager"''. It sports an interface that recalls Amiga GUI Workbench window manager which presents a desktop environment paradigm, and its graphical aspect is enhanced with Magical User Interface features and styleguides. It supports themes and various types of icons such as Amiga Icons planar style ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

AmigaOS 4
AmigaOS 4 (abbreviated as OS4 or AOS4) is a line of Amiga operating systems which runs on PowerPC microprocessors. It is mainly based on AmigaOS 3.1 source code developed by Commodore, and partially on version 3.9 developed by Haage & Partner. "The Final Update" (for OS version 4.0) was released on 24 December 2006 (originally released in April 2004) after five years of development by the Belgian company Hyperion Entertainment under license from Amiga, Inc. for AmigaOne registered users.http://www.hyperion-entertainment.biz/8080/news/2007-01-01 History During the five years of development, purchasers of AmigaOne machines could download pre-release versions of AmigaOS 4.0 from Hyperion's repository as long as these were made available. On 20 December 2006, Amiga, Inc. terminated the contract with Hyperion Entertainment to produce or sell AmigaOS 4. Nevertheless, AmigaOS 4.0 was released commercially for Amigas with PowerUP accelerator cards in November 2007 (having been avail ...

Ambient Desktop
Ambient is a MUI-based desktop environment for MorphOS. Its development was started in 2001 by David Gerber. Its main goals were that it should be fully asynchronous, simple and fast. Ambient remotely resembles Workbench and Directory Opus Magellan trying to mix the best of both worlds. Features Ambient does not strictly follow the Amiga Workbench interface paradigm but there are still many similarities: while programs are called tools, program attributes are called tooltypes, data files are projects and directories are drawers. * support for ARexx scripting language * default icon library for hundreds of fileformats * fully asynchronous, multi-threaded design * fast asynchronous file I/O functions and file notifications * support for PNG and other Amiga icon formats * built-in icon, workbench and wbstart libraries * built-in applications like disk formatting and commodities manager * panels which are used as program launchers Ambient is localized for various languages and wh ...

Object Oriented
Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which can contain data and code. The data is in the form of fields (often known as attributes or ''properties''), and the code is in the form of procedures (often known as ''methods''). A common feature of objects is that procedures (or methods) are attached to them and can access and modify the object's data fields. In this brand of OOP, there is usually a special name such as or used to refer to the current object. In OOP, computer programs are designed by making them out of objects that interact with one another. OOP languages are diverse, but the most popular ones are class-based, meaning that objects are instances of classes, which also determine their types. Many of the most widely used programming languages (such as C++, Java, Python, etc.) are multi-paradigm and they support object-oriented programming to a greater or lesser degree, typically in combination with impera ...
