Standard Widget Toolkit
The Standard Widget Toolkit (SWT) is a graphical widget toolkit for use with the Java platform. It was originally developed by Stephen Northover at IBM and is now maintained by the Eclipse Foundation in tandem with the Eclipse IDE. It is an alternative to the Abstract Window Toolkit (AWT) and Swing Java graphical user interface (GUI) toolkits provided by Sun Microsystems as part of the Java Platform, Standard Edition (J2SE). To display GUI elements, the SWT implementation accesses the native GUI libraries of the operating system using Java Native Interface (JNI) in a manner that is similar to those programs written using operating system-specific application programming interfaces (APIs). Programs that call SWT are portable, but the implementation of the toolkit, despite part of it being written in Java, is unique for each platform. The toolkit is free and open-source software distributed under the Eclipse Public License, which is approved by the Open Source Initiative. History ...

Java Native Interface
In software design, the Java Native Interface (JNI) is a foreign function interface programming framework that enables Java code running in a Java virtual machine (JVM) to call and be called by native applications (programs specific to a hardware and operating system platform) and libraries written in other languages such as C, C++ and assembly. Objectives JNI enables programmers to write native methods to handle situations when an application cannot be written entirely in the Java programming language, e.g. when the standard Java class library does not support the platform-specific features or program library. It is also used to modify an existing application (written in another programming language) to be accessible to Java applications. Many of the standard library classes depend on JNI to provide functionality to the developer and the user, e.g. file I/O and sound capabilities. Including performance- and platform-sensitive API implementations in the standard library allow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eclipse (software)
Eclipse is an integrated development environment (IDE) used in computer programming. It contains a base workspace and an extensible plug-in (computing), plug-in system for customizing the environment. It is the second-most-popular IDE for Java (programming language), Java development, and, until 2016, was the most popular. Eclipse is written mostly in Java and its primary use is for developing Java applications, but it may also be used to develop applications in other programming languages via plug-ins, including Ada (programming language), Ada, ABAP, C (programming language), C, C++, C Sharp (programming language), C#, Clojure, COBOL, D (programming language), D, Erlang (programming language), Erlang, Fortran, Groovy (programming language), Groovy, Haskell (programming language), Haskell, JavaScript, Julia (programming language), Julia, Lasso (programming language), Lasso, Lua (programming language), Lua, Software AG, NATURAL, Perl, PHP, Prolog, Python (programming language), Py ...

Integrated Development Environment
An integrated development environment (IDE) is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of at least a source code editor, build automation tools and a debugger. Some IDEs, such as NetBeans and Eclipse, contain the necessary compiler, interpreter, or both; others, such as SharpDevelop and Lazarus, do not. The boundary between an IDE and other parts of the broader software development environment is not well-defined; sometimes a version control system or various tools to simplify the construction of a graphical user interface (GUI) are integrated. Many modern IDEs also have a class browser, an object browser, and a class hierarchy diagram for use in object-oriented software development. Overview Integrated development environments are designed to maximize programmer productivity by providing tight-knit components with similar user interfaces. IDEs present a single program i ...

VisualAge
VisualAge is a family of computer integrated development environments from IBM, which supports multiple programming languages. VisualAge was first released in October 1993 and was discontinued April 30, 2007 and its web page removed in September 2011. VisualAge was also marketed as VisualAge Smalltalk, and in 2005, Instantiations, Inc. acquired the worldwide rights to this product. IBM has stated that XL C/C++ is the followup product to VisualAge. Early history VisualAge was created in the IBM development lab in Research Triangle Park, North Carolina, which was established in 1984 and had responsibility for application development tools. The EZ-VU dialog manager product, a personal computer derivative of the user interface elements of the ISPF 327x product was one of the first products in this family. The lab also had a group which was one of the early adopters of object-oriented programming technologies within IBM using an internally developed language called ClassC to develop ...

Object Technology International
Object Technology International (OTI) was founded in Ottawa, Ontario (Canada) in 1988 and acquired by IBM in 1996. OTI, in conjunction with the IBM development lab in Cary, NC, developed the VisualAge line Smalltalk and Java development tools that eventually culminated in the open source Eclipse An eclipse is an astronomical event that occurs when an astronomical object or spacecraft is temporarily obscured, by passing into the shadow of another body or by having another body pass between it and the viewer. This alignment of three ce ... tool platform and integrated development environment (IDE). OTI continued to operate with many of the same employees as it did when it was purchased by IBM until 2003-2004, when it was gradually disbanded as a distinct entity and its remaining employees absorbed into IBM.

Java 2D
Java 2D is an API for drawing two-dimensional graphics using the Java programming language. Every Java 2D drawing operation can ultimately be treated as ''filling'' a ''shape'' using a ''paint'' and ''compositing'' the result onto the screen. Organization The Java 2D API and its documentation are available for download as a part of JDK 6. Java 2D API classes are organised into the following packages in JDK 6: *' The main package for the Java Abstract Window Toolkit. *' The Java standard library of two dimensional geometric shapes such as lines, ellipses, and quadrilaterals. *' The library for manipulating glyphs in Java. *' The library dealing with the many different ways that color can be represented. *' The library for manipulating graphical images. *' The library of tools for writing to paper. Basic concepts These objects are a necessary part of every Java 2D drawing operation. Shapes A ''shape'' in Java 2D is a boundary which defines an inside and an outside. Pixels inside ...

Software Component
Component-based software engineering (CBSE), also called component-based development (CBD), is a branch of software engineering that emphasizes the separation of concerns with respect to the wide-ranging functionality available throughout a given software system. It is a reuse-based approach to defining, implementing and composing loosely coupled independent components into systems. This practice aims to bring about an equally wide-ranging degree of benefits in both the short-term and the long-term for the software itself and for organizations that sponsor such software. Software engineering practitioners regard components as part of the starting platform for service-orientation. Components play this role, for example, in web services, and more recently, in service-oriented architectures (SOA), whereby a component is converted by the web service into a ''service'' and subsequently inherits further characteristics beyond that of an ordinary component. Components can produce or co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Widget (computing)
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 widget to ...

Wrapper Library
Wrapper libraries (or library wrappers) consist of a thin layer of code (a "shim") which translates a library's existing interface into a compatible interface. This is done for several reasons: * To refine a poorly designed or complicated interface * Allow code to work together which otherwise cannot (e.g. incompatible data formats) * Enable cross language and/or runtime interoperability Wrapper libraries can be implemented using the adapter, façade, and to a lesser extent, proxy design patterns. Structure and implementation The specific way in which a wrapper library is implemented is highly specific to the environment it is being written in and the scenarios which it intends to address. This is especially true in the case when cross language/runtime interoperability is a consideration. Example The following provides a general illustration of a common wrapper library implementation. In this example, a C++ interface acts as a "wrapper" around a C-language interface. C in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
