Tri-state Check Box
A checkbox (check box, tickbox, tick box) is a graphical widget that allows the user to make a binary choice, i.e. a choice between one of two possible mutually exclusive options. For example, the user may have to answer 'yes' (checked) or 'no' (not checked) on a simple yes/no question. Checkboxes are shown as empty boxes when unchecked, and with a tick or cross inside (depending on the graphical user interface) when checked. A caption describing the meaning of the checkbox is normally shown adjacent to the checkbox. Inverting the state of a checkbox is done by clicking the mouse on the box, or the caption, or by using a keyboard shortcut, such as the space bar. Often, a series of checkboxes is presented, each with a binary choice between two options. The user may then select several of the choices. This is contrasted with the radio button, in which only a single option is selectable from several mutually-exclusive choices. Checkboxes may be disabled (indicated " greyed ou ...

Checkbox2
A checkbox (check box, tickbox, tick box) is a graphical widget that allows the user (computing), user to make a binary choice, i.e. a choice between one of two possible mutually exclusive options. For example, the user may have to answer 'yes' (checked) or 'no' (not checked) on a simple yes–no question, yes/no question. Checkboxes are shown as empty boxes when unchecked, and with a check mark, tick or cross inside (depending on the graphical user interface) when checked. A caption describing the meaning of the checkbox is normally shown adjacent to the checkbox. Inverting the state of a checkbox is done by clicking the mouse on the box, or the caption, or by using a keyboard shortcut, such as the space bar.

File Transfer Protocol
The File Transfer Protocol (FTP) is a standard communication protocol used for the transfer of computer files from a server to a client on a computer network. FTP is built on a client–server model architecture using separate control and data connections between the client and the server. FTP users may authenticate themselves with a plain-text sign-in protocol, normally in the form of a username and password, but can connect anonymously if the server is configured to allow it. For secure transmission that protects the username and password, and encrypts the content, FTP is often secured with SSL/TLS (FTPS) or replaced with SSH File Transfer Protocol (SFTP). The first FTP client applications were command-line programs developed before operating systems had graphical user interfaces, and are still shipped with most Windows, Unix, and Linux operating systems. Many dedicated FTP clients and automation utilities have since been developed for desktops, servers, mobile d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Button
A radio button or option button is a graphical control element that allows the user to choose only one of a predefined set of mutually exclusive options. The singular property of a radio button makes it distinct from checkboxes, where the user can select and unselect any number of items. Radio buttons are arranged in groups of two or more and displayed on screen as, for example, a list of circular holes that can contain white space (for unselected) or a dot (for selected). Each radio button is normally accompanied by a label describing the choice that the radio button represents. The choices are mutually exclusive; when the user selects a radio button, any previously selected radio button in the same group becomes deselected (making it so only one can be selected). Selecting a radio button is done by clicking the mouse on (or touching the screen over) the button, or the caption, or by using a keyboard shortcut. Etymology Radio buttons are named after the physical buttons tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tick-box Culture
Tick-box culture or in U.S. English check-box culture, is described as bureaucratic and external impositions on professional working conditions, which can be found in many organizations around the world.Steven PooleTickbox by David Boyle review – thinking inside the box: From call centres to management consultancy to government, decision-making is being dehumanised. We need to take a stand against the culture of targets The Guardian, 16 January 2020 Another related term is the culture of performativity. Origin According to David Boyle, the tick-box culture emerged with the introduction of targets and key performance indicators in corporate governance and official bureaucracy; it resulted in overzealous focus on rules and regulations rather than issues and people.Boyle, David''Tickbox'' Little, Brown Book Group Limited, 2020 For Boyle, the tick-box culture is associated with dehumanized decision-making in organizational settings that manifests itself in the growth of management c ...

Mozilla
Mozilla is a free software community founded in 1998 by members of Netscape. The Mozilla community uses, develops, publishes and supports Mozilla products, thereby promoting free software and open standards. The community is supported institutionally by the Nonprofit organization, non-profit Mozilla Foundation and its tax-paying subsidiary, the Mozilla Corporation. List of Mozilla products, Mozilla's current products include the Firefox web browser, Mozilla Thunderbird, Thunderbird e-mail client (now through a subsidiary), the Bugzilla bug tracking system, the Gecko (software), Gecko layout engine, and the Pocket (service), Pocket "read-it-later-online" service. History On January 23, 1998, Netscape announced that its Netscape Communicator browser software would be free, and that its source code would also be free. One day later, Jamie Zawinski of Netscape registered . The project took its name, "Mozilla", from the original code name of the Netscape Navigator browser—a por ...

HTML Element
An HTML element is a type of HTML (HyperText Markup Language) document component, one of several types of HTML nodes (there are also text nodes, comment nodes and others). The first used version of HTML was written by Tim Berners-Lee in 1993 and there have since been many versions of HTML. The current de facto standard is governed by the industry group WHATWG and is known as the HTML Living Standard. An HTML document is composed of a tree of simple HTML nodes, such as text nodes, and HTML elements, which add semantics and formatting to parts of a document (e.g., make text bold, organize it into paragraphs, lists and tables, or embed hyperlinks and images). Each element can have HTML attributes specified. Elements can also have content, including other elements and text. Concepts Elements vs. tags As is generally understood, the position of an element is indicated as spanning from a start tag and is terminated by an end tag. This is the case for many, but not all, elem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Form (web)
A webform, web form or HTML form on a web page allows a user to enter data that is sent to a server for processing. Forms can resemble paper or database forms because web users fill out the forms using checkboxes, radio buttons, or text fields. For example, forms can be used to enter shipping or credit card data to order a product, or can be used to retrieve search results from a search engine. Description Forms are enclosed in the HTML <form> element. This HTML element specifies the communication endpoint the data entered into the form should be submitted to, and the method of submitting the data, GET or POST. Elements Forms can be made up of standard graphical user interface elements: * <text> — a simple text box that allows input of a single line of text. * <email> - a type of <text> that requires a partially validated email address * <number> - a type of <text> that requires a number * <password> — similar to <tex ...

Toggle Switch (widget)
A toggle switch is a graphical control element that allows the user to make a choice between two mutually exclusive states (such as on/off). Originally toggle switches were used primary in touchscreen-based user interfaces, but they have later become commonplace in desktop and web applications. Toggle switches have a similar function as checkboxes, but unlike checkboxes, interacting with a toggle switch usually has an immediate effect on the application or system. Usability Early research on touchscreen interfaces has identified usability issues with toggle switches. A common problem is ambiguous state indication: for example does the label "on" indicate the current state of the switch or the resulting state after interacting with it. Communicating affordance In psychology, affordance is what the environment offers the individual. In design, affordance has a narrower meaning; it refers to possible actions that an actor can readily perceive. American psychologist Jam ...

Unclick
In computer interface design, to unclick is to deselect a specific preference, typically by tapping a selected checkbox with a finger or cursor. As a result, the check mark image or dark circle inside the box is removed. Background As the Internet becomes an increasingly popular medium for marketers, vendors and marketers often presume that a user will prefer certain choices, such as receiving emails in the future, having specific computer settings, or preferring that specific programs will be operational when a computer is turned on. As a result, it is sometimes necessary for a user to ''unclick'' these choices to avoid exposure to unwanted advertising, or to avoid a situation in which a different website is chosen for one's home page. In Internet marketing, ''unclicking'' is often required for a user to avoid being billed automatically for unnecessary services, sometimes part of a deceptive business practice termed negative option billing.

Undo
Undo is an interaction technique which is implemented in many computer programs. It erases the last change done to the document, reverting it to an older state. In some more advanced programs, such as graphic processing, undo will negate the last command done to the file being edited. With the possibility of undo, users can explore and work without fear of making mistakes, because they can easily be undone. The expectations for undo are easy to understand: to have a predictable functionality, and to include all "undoable" commands. Usually undo is available until the user undoes all executed operations. But there are some actions which are not stored in the undo list, and thus they cannot be undone. For example, ''save file'' is not undoable, but is queued in the list to show that it was executed. Another action which is usually not stored, and thus not undoable, is ''scrolling'' or ''selection''. The opposite of to undo is to redo. The redo command reverses the undo or advances ...

Tree View
A tree view is a graphical widget (graphical control element) within a graphical user interface (GUI) in which users can navigate and interact intuitively with concise, hierarchical data presented as nodes in a tree-like format. It can also be called an outline view. Appearance A tree view is usually a vertical list of nodes arranged in a tree-like structure. Each node represents a single data item, displayed as an indented line of text or a rectangular box. The indentation (and sometimes a line drawn between nodes) is used to indicate levels of hierarchy. Every treeview has a ''root node'' from which all nodes descend. Below the root node and indented to the right are its child nodes. Each node has exactly one parent node and can have zero or more child nodes. If a node (other than the root node) has a child or children, it is called a ''branch node''. If it has no child, then it is a ''leaf node''. This creates a hierarchical tree-like structure, with branches and subbranches e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Three-valued Logic
In logic, a three-valued logic (also trinary logic, trivalent, ternary, or trilean, sometimes abbreviated 3VL) is any of several many-valued logic systems in which there are three truth values indicating ''true'', ''false'', and some third value. This is contrasted with the more commonly known bivalent logics (such as classical sentential or Boolean logic) which provide only for ''true'' and ''false''. Emil Leon Post is credited with first introducing additional logical truth degrees in his 1921 theory of elementary propositions. The conceptual form and basic ideas of three-valued logic were initially published by Jan Łukasiewicz and Clarence Irving Lewis. These were then re-formulated by Grigore Constantin Moisil in an axiomatic algebraic form, and also extended to ''n''-valued logics in 1945. Pre-discovery Around 1910, Charles Sanders Peirce defined a many-valued logic system. He never published it. In fact, he did not even number the three pages of notes where he defined ...
