Double-click
A double-click is the act of pressing a computer mouse button twice quickly without moving the mouse. Double-clicking allows two different actions to be associated with the same mouse button. It was developed by Bill Atkinson of Apple Computer (now Apple Inc.) for their Apple Lisa, Lisa project. Often, Point and click#Single click, single-clicking selects (or highlights) an object, while a double-click executes the function associated with that object. Following a link in a modern web browser is accomplished with only a single click, requiring the use of a second mouse button, "click and hold" delay, or modifier key to gain access to actions other than following the link. On touchscreens, the double-click is called "double-tap"; it's not used as much as double-click, but typically it functions as a zoom feature. ("triple-tap" sometimes used to zoom the whole screen.) On icons On most systems, double-clicking an icon in the file manager will perform a default action on the object r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triple-click
Triple-click is the action of clicking a computer mouse button three times quickly without moving the mouse. Along with clicking and double-clicking, triple-clicking allows three different actions to be associated with the same mouse button. Double-click#Difficulties, Criticism of the double-click mechanism is even more valid for triple-clicks. However, few applications assign critical actions to a triple click. Examples of usage On text In most text processing programs and edit controls triple-clicking with the primary mouse button (the left button for right-handers) on the text selects the entire line. If the edit control is not multiline, the entire text is selected. Microsoft Word A triple-click within a paragraph in the text area selects the entire paragraph. A triple-click in the left margin (when the mouse pointer is an up-and-to-the-right arrow) selects the entire document. Microsoft Works A triple-click within a paragraph in the text area selects the line. A triple-c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bill Atkinson
Bill Atkinson (born March 17, 1951) is an American computer engineer and photographer. Atkinson worked at Apple Computer from 1978 to 1990. Atkinson was the principal designer and developer of the graphical user interface (GUI) of the Apple Lisa and, later, one of the first thirty members of the original Apple Macintosh development team, and was the creator of the MacPaint application. He also designed and implemented QuickDraw, the fundamental toolbox that the Lisa and Macintosh used for graphics. QuickDraw's performance was essential for the success of the Macintosh GUI. He also was one of the main designers of the Lisa and Macintosh user interfaces. Atkinson also conceived, designed and implemented HyperCard, an early and influential hypermedia system. HyperCard put the power of computer programming and database design into the hands of non programmers. In 1994, Atkinson received the EFF Pioneer Award for his contributions. Education He received his undergraduate degree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Point And Click
Point and click are the actions of a computer user moving a pointer to a certain location on a screen (''pointing'') and then pressing a button on a mouse, usually the left button (''click''), or other pointing device. An example of point and click is in hypermedia, where users click on hyperlinks to navigate from document to document. Point and click can be used with any number of input devices varying from mouses, touch pads, trackpoint, joysticks, scroll buttons, and roller balls. User interfaces, for example graphical user interfaces, are sometimes described as "point-and-click interfaces", often to suggest that they are very easy to use, requiring that the user simply point to indicate their wishes. These interfaces are sometimes referred to condescendingly (e.g., by Unix users) as "click-and-drool" or "point-and-drool" interfaces. The use of this phrase to describe software implies that the interface can be controlled solely through the mouse (or some other means such a ...

Hysteresis
Hysteresis is the dependence of the state of a system on its history. For example, a magnet may have more than one possible magnetic moment in a given magnetic field, depending on how the field changed in the past. Plots of a single component of the moment often form a loop or hysteresis curve, where there are different values of one variable depending on the direction of change of another variable. This history dependence is the basis of memory in a hard disk drive and the remanence that retains a record of the Earth's magnetic field magnitude in the past. Hysteresis occurs in ferromagnetic and ferroelectric materials, as well as in the deformation of rubber bands and shape-memory alloys and many other natural phenomena. In natural systems it is often associated with irreversible thermodynamic change such as phase transitions and with internal friction; and dissipation is a common side effect. Hysteresis can be found in physics, chemistry, engineering, biology, and economics. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unix-like
A Unix-like (sometimes referred to as UN*X or *nix) operating system is one that behaves in a manner similar to a Unix system, although not necessarily conforming to or being certified to any version of the Single UNIX Specification. A Unix-like application is one that behaves like the corresponding Unix command or shell. Although there are general philosophies for Unix design, there is no technical standard defining the term, and opinions can differ about the degree to which a particular operating system or application is Unix-like. Some well-known examples of Unix-like operating systems include Linux and BSD. These systems are often used on servers, as well as on personal computers and other devices. Many popular applications, such as the Apache web server and the Bash shell, are also designed to be used on Unix-like systems. One of the key features of Unix-like systems is their ability to support multiple users and processes simultaneously. This allows users to run multipl ...

MacOS
macOS (; previously OS X and originally Mac OS X) is a Unix operating system developed and marketed by Apple Inc. since 2001. It is the primary operating system for Apple's Mac computers. Within the market of desktop and laptop computers it is the second most widely used desktop OS, after Microsoft Windows and ahead of ChromeOS. macOS succeeded the classic Mac OS, a Mac operating system with nine releases from 1984 to 1999. During this time, Apple cofounder Steve Jobs had left Apple and started another company, NeXT, developing the NeXTSTEP platform that would later be acquired by Apple to form the basis of macOS. The first desktop version, Mac OS X 10.0, was released in March 2001, with its first update, 10.1, arriving later that year. All releases from Mac OS X 10.5 Leopard and after are UNIX 03 certified, with an exception for OS X 10.7 Lion. Apple's other operating systems (iOS, iPadOS, watchOS, tvOS, audioOS) are derivatives of macOS. A promi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows 7
Windows 7 is a major release of the Windows NT operating system developed by Microsoft. It was released to manufacturing on July 22, 2009, and became generally available on October 22, 2009. It is the successor to Windows Vista, released nearly three years earlier. It remained an operating system for use on personal computers, including home and business desktops, laptops, tablet PCs and media center PCs, and itself was replaced in November 2012 by Windows 8, the name spanning more than three years of the product. Until April 9, 2013, Windows 7 original release included updates and technical support, after which installation of Service Pack 1 was required for users to receive support and updates. Windows 7's server counterpart, Windows Server 2008 R2, was released at the same time. The last supported version of Windows based on this operating system was released on July 1, 2011, entitled Windows Embedded POSReady 7. Extended support ended on January 14, 2020, over ten years a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
