WindowShade was a control panel extension for the classic Mac OS that allowed a user to double-click a window's title bar to "roll up" the window like a windowshade. When the window was "rolled up", only the title bar of the window was visible; the window's content area disappeared, allowing easier manipulation of the windows on the screen.
It debuted in System 7.5, [1] but disappeared in Mac OS 8, when the feature was implemented as a part of the Appearance Manager. A widget was added to the title bar in addition to the double-click method of collapsing a window. The entire feature disappeared with the release of Mac OS X; windows could be minimized to the Dock on the new system or, starting with Mac OS X 10.3, moved aside with Exposé. However, several third-party utilities, such as WindowShade X for Unsanity's Application Enhancer software, have brought the ability back to Mac OS. It has since reappeared as a commercial haxie (an unofficial modification to system software) and offers other features, like translucent windows and minimize-in-place. WindowShade X from Unsanity stopped working in Mac OS 10.7, and other third-party developers have since released applications such as WindowMizer from RGB World that keep the WindowShade feature working on Mac OS X 10.6 and greater.
The WindowShade control panel itself stems from a third-party utility originally written for System 6.0.7 by Rob Johnston. Apple purchased the rights to this software from the developer for use in System 7.5. [2]
Some window managers for Unix-like operating systems have a similar feature allowing windows to be set to "roll up" when the user double-clicks the title bar of a window. [3] Some window managers provide a titlebar button to access the functionality. While Microsoft Windows does not expose such a feature by default, in some versions if a window is minimized while no taskbar is available, the said window will become a "shade" at the bottom of the screen. An intentional shading implementation for Windows is provided by third-party software vendors.
An X window manager is a window manager that runs on top of the X Window System, a windowing system mainly used on Unix-like systems.
In computing, a window is a graphical control element. It consists of a visual area containing some of the graphical user interface of the program it belongs to and is framed by a window decoration. It usually has a rectangular shape that can overlap with the area of other windows. It displays the output of and may allow input to one or more processes.
System 7, codenamed "Big Bang", and later also known as Mac OS 7, is a graphical user interface-based operating system for Macintosh computers and is part of the classic Mac OS series of operating systems. It was introduced on May 13, 1991, by Apple Computer It succeeded System 6, and was the main Macintosh operating system until it was succeeded by Mac OS 8 in 1997. Current for more than six years, System 7 was the longest-lived major version series of the classic Macintosh operating system. Features added with the System 7 release included virtual memory, personal file sharing, QuickTime, QuickDraw 3D, and an improved user interface.
A desk accessory (DA) in computing is a small transient or auxiliary application that can be run concurrently in a desktop environment with any other application on the system. Early examples, such as Sidekick and Macintosh desk accessories, used special programming models to provide a small degree of multitasking on systems that initially did not have any other multitasking ability.
MultiFinder is an extension for the Apple Macintosh's classic Mac OS, introduced on August 11, 1987 and included with System Software 5. It adds cooperative multitasking of several applications at once – a great improvement over the previous Macintosh systems, which can only run one application at a time. With the advent of System 7, MultiFinder became a standard integrated part of the operating system and remained so until the introduction of Mac OS X.
Mission Control is a feature of the macOS operating system. Dashboard, Exposé, and Spaces were combined and renamed Mission Control in 2011 with the release of Mac OS X 10.7 Lion. Exposé was first previewed on June 23, 2003, at the Apple Worldwide Developers Conference as a feature of the then forthcoming Mac OS X 10.3 Panther.
The Taskbar is a graphical user interface element that has been part of Microsoft Windows since Windows 95, displaying and facilitating switching between running programs. The Taskbar and the associated Start Menu were created and named in 1993 by Daniel Oran, a program manager at Microsoft who had previously collaborated on Great ape language research with the behavioral psychologist B.F. Skinner at Harvard.
Aqua is the graphical user interface, design language and visual theme of Apple's macOS operating system. It was originally based on the theme of water, with droplet-like components and a liberal use of reflection effects and translucency. Its goal is to "incorporate color, depth, translucence, and complex textures into a visually appealing interface" in macOS applications. At its introduction, Steve Jobs noted that "... it's liquid, one of the design goals was when you saw it you wanted to lick it".
Mac OS 8 is an operating system that was released by Apple Computer on July 26, 1997. It includes the largest overhaul of the classic Mac OS experience since the release of System 7, approximately six years before. It places a greater emphasis on color than prior versions. Released over a series of updates, Mac OS 8 represents an incremental integration of many of the technologies which had been developed from 1988 to 1996 for Apple's overly ambitious OS named Copland. Mac OS 8 helped modernize the Mac OS while Apple developed its next-generation operating system, Mac OS X.
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.
The Appearance Manager is a component of Mac OS 8 and Mac OS 9 that controls the overall look of the Macintosh graphical user interface widgets and supports several themes. It was originally developed for Apple's ill-fated Copland project, but with the cancellation of this project the system was moved into newer versions of the Mac OS. The Appearance Manager is also available free as part of a downloadable SDK for System 7.
Unsanity was a macOS shareware software developer founded in May 2000, notable for coining the term "haxie". Unsanity produced Mac utilities that relied on their own Application Enhancer, a utility that modified the system and other applications. Software incompatibility with Mac OS X Leopard, Snow Leopard, and Lion ended Unsanity's offerings.
A compositing manager, or compositor, is software that provides applications with an off-screen buffer for each window. The compositing manager composites the window buffers into an image representing the screen and writes the result into the display memory. A compositing window manager is a window manager that is also a compositing manager.
The Apple Developer Tools are a suite of software tools from Apple to aid in making software dynamic titles for the macOS and iOS platforms. The developer tools were formerly included on macOS install media, but are now exclusively distributed over the Internet. As of macOS 10.12, Xcode is available as a free download from the Mac App Store.
Spaces was a virtual desktop feature of Mac OS X, introduced in Mac OS X 10.5 Leopard. It was announced by Steve Jobs during the opening keynote at the Worldwide Developers Conference on August 7, 2006. As of Mac OS X 10.7 Lion, it has been incorporated into Mission Control.
The Apple menu is a drop-down menu that is on the left side of the menu bar in the classic Mac OS, macOS and A/UX operating systems. The Apple menu's role has changed throughout the history of Apple Inc.'s operating systems, but the menu has always featured a version of the Apple logo.
WindowLab is an X window manager for Unix-like systems. It is based on aewm and retains that window manager's lightweight aesthetic. In many aspects, WindowLab has looked to the Amiga's user interface for inspiration without cloning it completely. Its top-level menu bar is accessed by a right click as on the Amiga and it follows Fitts's law of usability in that once the mouse enters the menu area it is constrained there in both the horizontal and vertical directions. Unlike on the Amiga, the menu bar is not controlled by applications; it is a global launcher menu which is populated by a dot file in the user's home directory containing a list of menu titles and commands.
OS X Lion, also known as Mac OS X Lion, is the eighth major release of macOS, Apple's desktop and server operating system for Mac computers.
Mac OS is the series of operating systems developed for the Macintosh family of personal computers by Apple Computer from 1984 to 2001, starting with System 1 and ending with Mac OS 9. The Macintosh operating system is credited with having popularized the graphical user interface concept. It was included with every Macintosh that was sold during the era in which it was developed, and many updates to the system software were done in conjunction with the introduction of new Macintosh systems.
