  Widget toolkit - Wikipedia, the free encyclopedia
In computer programming, widget toolkits (or GUI toolkits) are sets of basic building elements for graphical user interfaces.
This framework is a wrapper for the Windows API (Win32API), and not an independent toolkit.
The Standard Widget Toolkit is a native widget toolkit for Java that was invented as part of the Eclipse project.

In the X Toolkit, a widget is the combination of an X window or subwindow and its associated input and output semantics.
Command widgets are often referred to as ``push buttons.'' When the pointer is over a Command widget, the widget becomes highlighted by drawing a rectangle around its perimeter.
It is often used with a Porthole widget to move, or ``scroll,'' a third widget in two dimensions, in which case the slider's size and position gives feedback as to what portion of the third widget is visible.

This identifier is then used for all further operations on the widget: the widget is invoked, hidden, displayed, and destroyed by passing this identifier to widget functions.
For example, the File Widget allows users to peruse the file system and select a file; when the user is done the selected file is returned to the application program by invoking an application-program-supplied function that was given to the File Widget for this purpose.
The depict widget is the most complex of the Daylight Widgets, as it has several modes of operation and has a callback function to return results in several forms.

 widget - a Whatis.com definition   (Site not responding. Last check: 2007-11-06)
Widgets include icons, pull-down menus, buttons, selection boxes, progress indicators, on-off checkmarks, scroll bars, windows, window edges (that let you resize the window), toggle buttons, forms, and many other devices for displaying information and for inviting, accepting, and responding to user actions.
In object-oriented programming (OOP), each type of widget is defined as a class (or a subclass under a broad generic widget class) and is always associated with a particular window.
In the AIX Enhanced X-Window Toolkit, a widget is the fundamental data type.

 The Context Toolkit: Aiding the Development of Context-Enabled Applications
A widget that tracks the location of a user within a building or a city notifies the application only when the user moves from one room to another, or from one street corner to another, and doesn’t report less significant moves to the application.
For example, a widget designed to detect the kind of activity people in a classroom are engaged in could combine the information provided by presence widgets and activity sensing widgets using, for instance, audio and video analysis.
The context toolkit was inspired by the success of GUI toolkits and has similar benefits: building blocks called context widgets provide reusable solutions for context handling; by delegating details of context handling to the toolkit, we achieve separation of concerns between context sensing and application semantics.

 TIP #41: Paned Window Tk Widget   (Site not responding. Last check: 2007-11-06)
For a Motif-style paned window with two panes, this means five widgets are created (one frame for the paned window container widget; one frame for each pane; one frame for the sash; one frame for the sash handle).
Developers are reluctant to use those extension widgets because they cannot rely on their presence in an end-user's system, and because of concerns of version incompatibilities between the extension and the core.
WIDGET COMMAND The panedwindow command creates a new Tcl command whose name is the same as the path name of the panedwindow's window.

 Widget Overview
The widget toolkit maintanance is reduced and it requires fewer platform secific developers to add new features and maintain it.
The most important, is that when the widgets live inside the layout engine they are to do as little as possible, they must dispatch all their events and then wait to be told what to do.
Currently, most all the widgets are developed from the native platform widgets with the exception of the Toolbar, the Toolbar Manager, the ImageButton, and the MenuButton (a button with an assosicated drop down menu).

 Kenton Lee: Preventing X Toolkit Widget Resource Syntax Errors
One of the nice features of the X Toolkit is that it does provide a simple interface to a powerful feature and this simple interface does cut down on programming errors.
You can set and get X Toolkit widget resources through a number of different functions, but the general syntax of all the calls is similar.
Due to the complexity of widget internals, I cannot recommend using debuggers techniques to attempt to modify the values of widget structure members.

 Standard Widget Toolkit   (Site not responding. Last check: 2007-11-06)
The Standard Widget Toolkit (SWT) is a widget toolkit for Java developers that provides a portable API and tight integration with the underlying native OS GUI platform.
A common issue in widget toolkit design is the tension between portable toolkits and platform integration.
For example, the OSF/Motif 2.1 widget toolkit does not contain a tree widget, so SWT provides an emulated tree widget on Motif 2.1 that is API compatible with the Windows native implementation.

 GUI toolkits: What are your options? - SunWorld - March 1998
X is not a toolkit, though, at least not for the purpose of this article.
Traditionally, one of the attractions of the high-end toolkits from such vendors as Neuron Data and Visual Edge has been that they managed the complexity of working with Motif on different platforms, and sometimes even targeted other low-level toolkits than Motif.
What that weight buys is a rich widget set, accessibility support for the blind or those with other disabilities, drag-and-drop functionality, and a pluggable look and feel.

 Java 2D imaging for the Standard Widget Toolkit   (Site not responding. Last check: 2007-11-06)
SWT (Standard Widget Toolkit) is the widget toolkit that is used on the Eclipse platform.
SWT's popularity springs from the fact that it is a cross-platform toolkit that makes use of native widgets and has a similar level of functionality to Swing and other modern toolkits.
Unfortunately, Java 2D is designed to be used exclusively with the AWT or Swing toolkits, and SWT doesn't yet provide such extended 2D capabilities.

 sforce blog: AJAX Toolkit - Konfabulator Widget
I was interested in where the data was coming from in the stock ticker widget that comes with the installation of K. What I found is that K exposes an object that is very similar to an XMLHttpRequest and the MSXML peer objects called URL.
The widget attached is a modification to Arlo Rose's mini what to do widget.
This means that the toolkit included in this widget is not the toolkit endorsed by salesforce.com, but I'm fairly certains some of these changes will make it into the official toolkit.

 Widgets   (Site not responding. Last check: 2007-11-06)
Where possible, widget toolkit elements are built around the operating system's native dialogs and controls; as a result, there are instances where the toolkit behaves differently from operating system to operating system.
Base widgets (created with the WIDGET_BASE routine) play an especially important role in creating widget-based IDL applications because their behavior controls the way the application and its components are iconized, layered, and destroyed.
Handle individual widget events carefully, and be sure to test your code on all platforms supported by your application.

I was a member at that time of a DigiGroups engineering team charged with developing the GUI widgets for this next generation application.
In contrast to the GUI toolkit of the DynaSurv API, the DigiGroups GUI rivaled a desktop application in its richness and attention to detail.
Rather the widgets on the client generated the HTML themselves and integrated the data into the presentation themselves, under direction from the JavaScript controller object (also living on the browser).

 SWT: The Standard Widget Toolkit
Developers demand portable graphics and widgets to allow them to build user interfaces that are competitive with shrink-wrapped applications built using platform specific tools.
How can this be true when SWT uses native widgets that provide an API in C? The answer is that Java provides a native interface to C (JNI) that is used by SWT to invoke the operating system from Java code.
For example, implementing drag and drop and integrating it with the widgets was not difficult, despite the fact that these are two independent services.

 The GLOW Toolkit   (Site not responding. Last check: 2007-11-06)
The GLOW Toolkit is a cross-platform object-oriented framework for building interactive applications using OpenGL or similar APIs such as Mesa.
It is, at its heart, an C++ wrapper for GLUT, providing a fully object-oriented API for creating windows, menus and other GUI elements, and for event handling.
GLOW also features an extensible cross-platform widget library for building powerful user interfaces; a number of useful utilities such as an implementation of the arcball 3D manipulator; and, of course, full integration with OpenGL as the imaging API.

 Sharp Widget Toolkit #WT (SharpWT)
The Sharp Widget Toolkit (SharpWT or #WT for short) is a port of the Java SWT (Standard Widget Toolkit) to C# and.NET.
The initial porting effort started when the SharpDevelop team wanted to move away from Windows Forms to a different UI toolkit that would allow for portability but still have the native look and feel as well the performance on the platforms it runs on.
The project is now well under way for.NET on Windows and Mono on Linux, and we are glad that we were joined in our effort by other developers that help us on important issues such as portability, stability, samples and documentation.
