XML Binding Language
XBL (''XML Binding Language'') is an XML-based markup language for altering the behavior of XUL widgets. It was devised at Netscape in the late 1990s as an extension of XUL. The primary use of XBL was in the Firefox web browser, but Mozilla deprecated it in 2017 and completely removed it from Firefox in 2019. However, the UXP fork of Firefox intends to continue supporting XBL indefinitely. Mozilla attempted to standardize XBL 2.0 via W3C in 2007, but due to lack of interest from other web browser vendors, abandoned it in 2012. The Shadow DOM specification acknowledges XBL as a strong influence. Overview XUL defines the user interface layout of an application. CSS rules can be used to change the appearance of various XUL elements. But XBL is needed to alter the behavior of a XUL widget, such as a scroll bar. An XBL file contains bindings, each of which describes the behavior of a XUL widget. The root element of an XBL file is the element, which contains one or more el ...

Markup Language
Markup language refers to a text-encoding system consisting of a set of symbols inserted in a text document to control its structure, formatting, or the relationship between its parts. Markup is often used to control the display of the document or to enrich its content to facilitating automated processing. A markup language is a set of rules governing what markup information may be included in a document and how it is combined with the content of the document in a way to facilitate use by humans and computer programs. The idea and terminology evolved from the "marking up" of paper manuscripts (i.e., the revision instructions by editors), which is traditionally written with a red pen or blue pencil on authors' manuscripts. Older markup languages, which typically focus on typography and presentation, include troff, TeX, and LaTeX. Scribe and most modern markup languages, for example XML, identify document components (for example headings, paragraphs, and tables), with t ...

User Interface
In the industrial design field of human–computer interaction, a user interface (UI) is the space where interactions between humans and machines occur. The goal of this interaction is to allow effective operation and control of the machine from the human end, while the machine simultaneously feeds back information that aids the operators' decision-making process. Examples of this broad concept of user interfaces include the interactive aspects of computer operating systems, hand tools, heavy machinery operator controls and process controls. The design considerations applicable when creating user interfaces are related to, or involve such disciplines as, ergonomics and psychology. Generally, the goal of user interface design is to produce a user interface that makes it easy, efficient, and enjoyable (user-friendly) to operate a machine in the way which produces the desired result (i.e. maximum usability). This generally means that the operator needs to provide minimal in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SXBL
sXBL (SVG's XML Binding Language) is a mechanism for defining the presentation and interactive behavior of elements described in a namespace other than SVG's (an XML language supporting vector graphics, user events and scripted behavior). sXBL is very similar to XBL, as it does for SVG documents what XBL does for XUL documents. For example, it is possible to define a generic scrollArea in sXBL and use it in SVG documents. History, objectives, and future sXBL specification derived from a specification called RCC (Rendering Custom Content) that was embedded in a 2003 working draft of the SVG 1.2 specification. The RCC part of the specification has since been removed in favor of the sXBL more modular approach. As stated in the sXBL working draft: ''sXBL is intended to be an SVG-specific first version of a more general-purpose XBL specification (e.g., "XBL 2.0"). The intent is that, in the future, a general-purpose and modularly-defined XBL specification will be developed which wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Uniform Resource Locator
A Uniform Resource Locator (URL), colloquially termed as a web address, is a reference to a web resource that specifies its location on a computer network and a mechanism for retrieving it. A URL is a specific type of Uniform Resource Identifier (URI), although many people use the two terms interchangeably. URLs occur most commonly to reference web pages (HTTP) but are also used for file transfer ( FTP), email ( mailto), database access ( JDBC), and many other applications. Most web browsers display the URL of a web page above the page in an address bar. A typical URL could have the form http://www.example.com/index.html, which indicates a protocol (http), a hostname (www.example.com), and a file name (index.html). History Uniform Resource Locators were defined in in 1994 by Tim Berners-Lee, the inventor of the World Wide Web, and the URI working group of the Internet Engineering Task Force (IETF), as an outcome of collaboration started at the IETF Living Documents birds o ...

Data Binding
In computer programming, data binding is a general technique that binds data sources from the provider and consumer together and synchronizes them. This is usually done with two data/information sources with different languages, as in XML data binding and UI data binding. In UI data binding, data and information objects of the same language, but different logic function are bound together (e.g., Java UI elements to Java objects). In a data binding process, each data change is reflected automatically by the elements that are bound to the data. The term data binding is also used in cases where an outer representation of data in an element changes, and the underlying data is automatically updated to reflect this change. As an example, a change in a TextBox element could modify the underlying data value. Data binding frameworks and tools List of examples of data binding frameworks and tools for different programming languages: C# .NET * Windows Presentation Foundation (WPF) * Bla ...

Scroll Bar
A scrollbar is an interaction technique or widget (GUI), widget in which continuous text, pictures, or any other content can be Scrolling, scrolled in a predetermined direction (up, down, left, or right) on a computer display, window (computing), window, or viewport so that all of the content can be viewed, even if only a fraction of the content can be seen on a device's screen at one time. It offers a solution to the problem of Web navigation, navigation to a known or unknown location within a two-dimensional information space. It was also known as a handle in the very first GUIs. They are present in a wide range of electronic devices including computers, graphing calculators, mobile phones, and portable media players. The user interacts with the scrollbar elements using some method of direct action, the scrollbar translates that action into scrolling commands, and the user receives feedback through a visual updating of both the scrollbar elements and the scrolled content.

Cascading Style Sheets
Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation of a document written in a markup language such as HTML or XML (including XML dialects such as SVG, MathML or XHTML). CSS is a cornerstone technology of the World Wide Web, alongside HTML and JavaScript. CSS is designed to enable the separation of content and presentation, including layout, colors, and fonts. This separation can improve content accessibility; provide more flexibility and control in the specification of presentation characteristics; enable multiple web pages to share formatting by specifying the relevant CSS in a separate .css file, which reduces complexity and repetition in the structural content; and enable the .css file to be cached to improve the page load speed between the pages that share the file and its formatting. Separation of formatting and content also makes it feasible to present the same markup page in different styles for different rende ...

Web Components
Web Components are a set of features that provide a standard component model for the Web allowing for encapsulation and interoperability of individual HTML elements. Primary technologies used to create them include: * Custom Elements: APIs to define new HTML elements * Shadow DOM: encapsulated DOM and styling, with composition * HTML Templates: HTML fragments that are not rendered, but stored until instantiated via JavaScript Features Custom Elements There are two parts to Custom Elements: autonomous custom elements and customized built-in elements. Autonomous custom elements are HTML elements that are entirely separated from native HTML elements; they are essentially built from the bottom up using the Custom Elements API. Customized built-in elements are elements that are built upon native HTML elements to reuse their functionality. Shadow DOM Shadow DOM is a functionality that allows the web browser to render DOM elements without putting them into the main documen ...

Graphical Widget
A graphical widget (also graphical control element or control) 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. Each widget facilitates a specific type of user-computer interaction, and appears as a visible part of the application's GUI as defined by the theme and rendered by the rendering engine. The theme makes all widgets adhere to a unified aesthetic design and creates a sense of overall cohesion. Some widgets support interaction with the user, for example labels, buttons, and check boxes. Others act as containers that group the widgets added to them, for example windows, panels, and tabs. Structuring a user interface with w ...
