Computer Software Widget KnowledgeBase By Essential Pathology, NNMI Computer Software Widget For most computer users, computer software widgets, or more simply widgets, may be considered as stand-alone simple software applications that allow the user to perform simple task or functions. But to be accurate and more comprehensive, a few related concepts need to be introduced. These are, in addition to software widgets, desktop widgets, Web widgets, and widget toolkit and graphic user interface. Software widgets: Software widgets are simple, stand-alone, task-oriented applications that provide single-purpose services or functions. It is a generic type of software application comprising portable programming code intended for one or more different software platforms. The term often implies that either the application, user interface, or both, are relatively simple and easy to use as opposed to a more complete software package such as a spreadsheet or word processor. The Web Application Formats Working Group in W3C released W3C standard to standardize some aspects of widgets. By their physical location, software widgets can be divided into two major categories: desktop widgets, and Web widgets. Desktop widgets (commonly just called widgets): Desktop widgets are a specialized GUI widget intended to run on a computer desktop for computer users to control simple utility functions such as showing the latest news, the current weather, the time, or a map program; or allowing users to control clocks, a calculator, photo viewers, or even a language translator, among other things. A desktop widget resides on the user’s desktop but uses little desktop space and computer resources, such as hard-drive device and RAM. Its purpose is to provide relevant information to the user in a non-intrusive manner and using few resources. Basically, desktop widgets enable the user to view on demand, encapsulated information from predetermined data sources. Most of the desktop widgets are available as free downloads from the vendors’ Web sites. A closely related concept is mobile widget. A mobile widget is the comparable equivalent for mobile devices (e.g. smart phones). Web widget: A web widget is a portable application installed and executed, typically by webmasters on HTML-based web pages, to offer site visitors simple functionality such as shopping, advertisements, videos, Web widgets are usually created by third party publishers and are distributed to web page owners who implement the widgets on their web page. In contrast to desktop widgets, web widgets do not reside in the user’s desktop computer or other mobile device. They are embedded in a web page and reside in the hosting server of the web page instead of the user's computer. Users can only access a web widget by visiting the web page. Widget toolkit: Desktop widgets can also work in constellation to create sophisticated applications. A set of widgets for use in designing applications with graphical user interfaces (GUIs) is called widget toolkit, or widget library. The toolkit includes a piece of software which is usually built on the top of an operating system, and provides programs with an application programming interface (API), allowing them to make use of widgets. An individual widget in a toolkit provides a single, low level function, and is prepared to communicate with other widgets in the toolkit. Widget toolkits can be either native or cross platform. The term, Graphical user interface, is mentioned a few times above. Graphical user interface (or GUI) is a type of user interface that allows users to interact with electronic devices © All Rights Reserved 2 - 1. March 2012 KnowledgeBase By Essential Pathology, NNMI with images rather than text commands. It allows a computer user to control and change the appearance of elements for operating a software application. The software widget most commonly encountered by regular users is in the graphical user interface format. In this context a widget may refer to a generic GUI element such as a check box, to an instance of that element, or to a customized collection of such elements used for a specific function or application. In this episode we introduced computer software widgets. They are stand-alone simple software applications that allow the user to perform simple task or functions. Software widgets residing in our personal computer devices are called desktop widgets; whereas those coming along and functioning on a webpage are called web widgets. As for all other episodes of this podcast, you can view the text summary on your Apple mobile devices or view the entire transcript on the web. ==== Summary ==== Software Widgets ● Portable, stand-alone, task-oriented software applications ● Provide single-purpose services or functions ● Simple and easy to use ● Embedded in a web page (web widgets) or in user’s desktop PC (desktop widgets) Desktop Widgets ● Portable software application that controls simple utility functions ● Are specialized GUI widgets residing in user desktop computer ● Use little desktop space and computer system resources ● Most are available as free downloads from Internet Web widgets ● Also portable software applications ● Allow users to perform simple functions ● Not reside in user desktop computer ● Usually embedded in a web page instead ● Publishers distribute them to web page owners Widget Toolkits ● Combine several widgets to form a single application ● A set of interrelated programming tools ● Used to design applications with GUI Reference / Suggested Readings Wikipedia: Software Widget.

Lupu <[email protected]> June 18, 2003 ii Abstract UNIX desktop environments are a mess. The proliferation of incompatible and inconsistent user interface toolkits is now the primary factor in the failure of enterprises to adopt UNIX as a desktop solution. This report documents the creation of a comprehensive, elegant framework for a complete windowing system, including a standardised graphical user interface toolkit. ‘Y’ addresses many of the problems associated with current systems, whilst keeping and improving on their best features. An initial implementation, which supports simple applications like a terminal emulator, a clock and a calculator, is provided. iii iv Acknowledgements Thanks to Daniel R¨uckert for supervising the project and for his help and advice regarding it. Thanks to David McBride for his assistance with setting up my project machine and providing me with an ATI Radeon for it. Thanks to Philip Willoughby for his knowledge of the POSIX standard and help with the GNU Autotools and some of the more obscure libc functions. Thanks to Andrew Suffield for his help with the GNU Autotools and Arch. Thanks to Nick Maynard and Karl O’Keeffe for discussions on window system and GUI design. Thanks to Tim Southerwood for discussions about possible features of Y. Thanks to Duncan White for discussions about the virtues of X.

  • Part I. GTK+ Overview: GTK+ 3 Reference Manual GTK+ Is a Library for Creating Graphical User Interfaces
    Part I. GTK+ Overview: GTK+ 3 Reference Manual GTK+ is a library for creating graphical user interfaces. It works on many UNIX-like platforms, Windows, and OS X. GTK+ is released under the GNU Library General Public License (GNU LGPL), which allows for flexible licensing of client applications. GTK+ has a C-based object-oriented architecture that allows for maximum flexibility. Bindings for many other languages have been written, including C++, Objective-C, Guile/ Scheme, Perl, Python, TOM, Ada95, Free Pascal, and Eiffel. GTK+ depends on the following libraries: GLib A general-purpose utility library, not specific to graphical user interfaces. GLib provides many useful data types, macros, type conversions, string utilities, file utilities, a main loop abstraction, and so on. GObject A library that provides a type system, a collection of fundamental types including an object type, a signal system. GIO A modern, easy-to-use VFS API including abstractions for files, drives, volumes, stream IO, as well as network programming and DBus communication. cairo Cairo is a 2D graphics library with support for multiple output devices. Pango Pango is a library for internationalized text handling. It centers around the PangoLayout object, representing a paragraph of text. Pango provides the engine for GtkTextView, GtkLabel, GtkEntry, and other widgets that display text. ATK ATK is the Accessibility Toolkit. It provides a set of generic interfaces allowing accessibility technologies to interact with a graphical user interface. For example, a screen reader uses ATK to discover the text in an interface and read it to blind users. GTK+ widgets have built-in support for accessibility using the ATK framework.

  • Cross-Platform 1 Cross-Platform
    Cross-platform 1 Cross-platform In computing, cross-platform, or multi-platform, is an attribute conferred to computer software or computing methods and concepts that are implemented and inter-operate on multiple computer platforms.[1] [2] Cross-platform software may be divided into two types; one requires individual building or compilation for each platform that it supports, and the other one can be directly run on any platform without special preparation, e.g., software written in an interpreted language or pre-compiled portable bytecode for which the interpreters or run-time packages are common or standard components of all platforms. For example, a cross-platform application may run on Microsoft Windows on the x86 architecture, Linux on the x86 architecture and Mac OS X on either the PowerPC or x86 based Apple Macintosh systems. A cross-platform application may run on as many as all existing platforms, or on as few as two platforms. Platforms A platform is a combination of hardware and software used to run software applications. A platform can be described simply as an operating system or computer architecture, or it could be the combination of both. Probably the most familiar platform is Microsoft Windows running on the x86 architecture. Other well-known desktop computer platforms include Linux/Unix and Mac OS X (both of which are themselves cross-platform). There are, however, many devices such as cellular telephones that are also effectively computer platforms but less commonly thought about in that way. Application software can be written to depend on the features of a particular platform—either the hardware, operating system, or virtual machine it runs on.

Contents 1 Toga Documentation, Release 0.2.0 2 Contents CHAPTER 1 Quickstart In your virtualenv, install Toga, and then run it: $ pip install toga-demo $ toga-demo This will pop up a GUI window showing the full range of widgets available to an application using Toga. 1.1 Prerequisites Toga has some minimum requirements: • If you’re on OS X, you need to be on 10.7 (Lion) or newer. • If you’re on Linux, you need to have GTK+ 3.4 or later. This is the version that ships with Ubuntu 12.04; you’ll need to have the python-gi (or python3-gi if you’re using Python 3) package installed. If you want to use the WebView widget, you’ll also need to have WebKit, plus the GI bindings to WebKit (gir1.2-webkit-3.0) installed. If these requirements aren’t met, Toga either won’t work at all, or won’t have full functionality. 1.2 Problems with source installs Internally, Toga is comprised of a number of subpackages - one for each platform it supports. If you install using wheels, the install process will correctly identify the required packages and install them.
