Application framework

In computer programming, an application framework consists of a software framework used by software developers to implement the standard structure of an application for a specific development environment (such as an operating system or a web application).

Application frameworks became popular with the rise of graphical user interfaces (GUIs), since these tended to promote a standard structure for applications. Programmers find it much simpler to create automatic GUI creation tools when using a standard framework, since this defines the underlying code structure of the application in advance. Developers usually use object-oriented programming techniques to implement frameworks such that the unique parts of an application can simply inherit from pre-existing classes in the framework.

Examples

Apple Computer developed one of the first commercial application frameworks, MacApp (first released in 1985), for the Macintosh. Originally written in an extended (object-oriented) version of Pascal, it later appeared rewritten in C++. Other popular frameworks for the Mac include Metrowerks' PowerPlant and MacZoop (both based on Carbon). Cocoa for Mac OS X offers a different approach to an application framework.

Free-software frameworks exist as part of the Mozilla, OpenOffice.org, GNOME, KDE, and Eclipse projects.

Microsoft markets a framework for developing Windows applications in C++ called the Microsoft Foundation Classes or MFC.

A number of frameworks can build cross-platform applications for Linux, Macintosh, and Windows from the same source code, such as Qt, the widget toolkits wxWidgets, FOX toolkit, or Eclipse RCP.
