The same as gadget

في البرمجة، الوَدَجَة (بالإنجليزية: widget) هي عنصر واجهة يتفاعل معه المستخدم، كنافذة أو مربع نص مثلا.
الخاصية المميزة للودجة هي أن توفر نقطة تفاعل للمعالجة المباشرة لنوع معين من البيانات.

الودجات هي الوحدات المرئية الأساسية التي تجمع في برمجية لتحتوي كل البيانات التي تعالجها تلك البرمجية ونقاط التفاعل معها.

In computer programming, a widget (or control) is an element of a graphical user interface (GUI) that displays an information arrangement changeable by the user, such as a window or a text box. The defining characteristic of a widget is to provide a single interaction point for the direct manipulation of a given kind of data. In other words, widgets are basic visual building blocks which, combined in an application, hold all the data processed by the application and the available interactions on this data.

A family of common reusable widgets has evolved for holding general information based on the PARC research for the Xerox Alto User Interface. Different implementations of these generic widgets are often packaged together in widget toolkits, which programmers use to build graphical user interfaces (GUIs). Most operating systems include a set of ready-to-tailor widgets that a programmer can incorporate in an application, specifying how it is to behave. Each type of widgets generally is defined as a class by object-oriented programming (OOP). Therefore, many widgets are derived from class inheritance.

Widgets are sometimes qualified as virtual to distinguish them from their physical counterparts, e.g. virtual buttons that can be clicked with a mouse cursor, vs. physical buttons that can be pressed with a finger.

A related (but different) concept is the desktop widget, a small specialized GUI application that provides some visual information and/or easy access to frequently used functions such as clocks, calendars, news aggregators, calculators and desktop notes. These kinds of widgets are hosted by a widget engine.
