Описание тега toolkit

A widget toolkit, widget library, or gui-toolkit is a set of widgets for use in designing applications with graphical user interfaces ( gui s).

The toolkit itself is a piece of software which is usually built on the top of an operating system, windowing system, or window manager and provides programs with an application programming interface ( api), allowing them to make use of widgets. Each widget facilitates a specific user-computer interaction, and appears as a visible part of the computer's GUI. Widget toolkits can be either native or cross-platform.
