Whois & Analysis for gtk.org

GTK+ (formerly GIMP Toolkit) is a cross-platform widget toolkit for creating graphical user interfaces.

It is licensed under the terms of the GNU Lesser General Public License, allowing both free and proprietary software to use it.

It is one of the most popular toolkits for the Wayland and X11 windowing systems, along with Qt.

The GNU Lesser General Public License (LGPL) is a free software license published by the Free Software Foundation (FSF).

The license allows developers and companies to use and integrate software released under the LGPL into their own (even proprietary) software without being required by the terms of a strong copyleft license to release the source code of their own components.

The license only requires software under the LGPL be modifiable by end users via source code availability.

For proprietary software, code under the LGPL is usually used in the form of a shared library, so that there is a clear separation between the proprietary and LGPL components.

The LGPL is primarily used for software libraries, although it is also used by some stand-alone applications.

Proprietary software is computer software for which the software's publisher or another person retains intellectual property rights — usually copyright of the source code, but sometimes patent rights.

In computer programming, an Application Programming Interface (API) is a set of subroutine definitions, protocols, and tools for building application software.

In general terms, it is a set of clearly defined methods of communication between various software components.

A good API makes it easier to develop a computer program by providing all the building blocks, which are then put together by the programmer.

In computing, cross-platform software (multi-platform, or platform independent software) is computer software that is implemented on multiple computing platforms.

Cross-platform software may be divided into two types; one requires individual building or compilation for each platform that it supports, and the other one can be directly run on any platform without special preparation, e.g., software written in an interpreted language or pre-compiled portable bytecode for which the interpreters or run-time packages are common or standard components of all platforms.
