GTK
GTK (formerly GIMP ToolKit and GTK+) is a free software cross-platform widget toolkit for creating graphical user interfaces (GUIs). It is licensed under the terms of the GNU Lesser General Public License, allowing both Free software, free and proprietary software to use it. It is one of the most popular toolkits for the Wayland (protocol), Wayland and X Window System core protocol, X11 windowing systems. The GTK team releases new versions on a regular basis. GTK 4 and GTK 3 are maintained, while GTK 2 is End-of-life product, end-of-life. GTK1 is independently maintained by the CinePaint project. Software architecture The GTK Library (computing), library contains a set of graphical control elements (Widget (GUI), widgets); version 3.22.16 contains 186 active and 36 deprecated widgets. GTK is an Object-oriented programming, object-oriented widget toolkit written in the programming language C (programming language), C; it uses GObject (that is, the GLib obje ...

GDK Software Architecture
GDK (GIMP Drawing Kit) is a library that acts as a wrapper around the low-level functions provided by the underlying windowing and graphics systems. GDK lies between the display server and the GTK library, handling basic rendering such as drawing primitives, raster graphics (bitmaps), cursors, fonts, as well as window events and drag-and-drop functionality. Like GTK Scene Graph Kit (GSK), GDK is part of GTK and licensed under the GNU Lesser General Public License (LGPL). Software architecture GTK is implemented on top of an abstraction layer called GDK, freeing GTK from low-level concerns like input gathering, drag and drop, and pixel format conversion. GDK is an intermediate layer which separates GTK from the details of the windowing system. GDK is an important part of GTK's portability. Since low-level cross-platform functionality is already provided by GLib, all that is needed to make GTK run on other platforms is to port GDK to the underlying operating system's g ...

GObject
The GLib Object System, or GObject, is a free software, free software library providing a portable object system and transparent cross-language interoperability. GObject is designed for use both directly in C (programming language), C programs to provide object-oriented C-based APIs and through language binding, bindings to other languages to provide transparent cross-language interoperability, e.g. PyGObject. History Depending only on GLib and libc, GObject is a cornerstone of GNOME and is used throughout GTK, Pango, Accessibility Toolkit, ATK, and most higher-level GNOME libraries like GStreamer and applications. Prior to GTK+ 2.0, code similar to GObject was part of the GTK codebase. (The name “GObject” was not yet in use — the common baseclass was called GtkObject.) At the release of GTK+ 2.0, the object system was extracted into a separate library due to its general utility. In the process, most non-GUI-specific parts of the GtkObject class were moved up into GOb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GUI Widget
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 ...

Widget Toolkit
A widget toolkit, widget library, GUI toolkit, or UX library is a library (computing), library or a collection of libraries containing a set of graphical control elements (called ''widgets'') used to construct the graphical user interface (GUI) of programs. Most widget toolkits additionally include their own Rendering (computer graphics), rendering engine. This engine can be specific to a certain operating system or windowing system or contain back-ends to interface with multiple ones and also with rendering APIs such as OpenGL, OpenVG, or EGL (API), EGL. The look and feel of the graphical control elements can be hard-coded or decoupled, allowing the graphical control elements to be Theme (computing), themed/Skin (computing), skinned. Overview Some toolkits may be used from other languages by employing language bindings. Graphical user interface builders such as e.g. Glade Interface Designer facilitate the authoring of GUIs in a WYSIWYG manner employing a user interface markup la ...

Proprietary Software
Proprietary software is computer software, software that grants its creator, publisher, or other rightsholder or rightsholder partner a legal monopoly by modern copyright and intellectual property law to exclude the recipient from freely sharing the software or modifying it, and—in some cases, as is the case with some patent-encumbered and EULA-bound software—from making use of the software on their own, thereby restricting their freedoms. Proprietary software is a subset of non-free software, a term defined in contrast to free and open-source software; non-commercial licenses such as CC BY-NC are not deemed proprietary, but are non-free. Proprietary software may either be closed-source software or source-available software. Types Origin Until the late 1960s, computers—especially large and expensive mainframe computers, machines in specially air-conditioned computer rooms—were usually leased to customers rather than Sales, sold.

Object-oriented Programming
Object-oriented programming (OOP) is a programming paradigm based on the concept of '' objects''. Objects can contain data (called fields, attributes or properties) and have actions they can perform (called procedures or methods and implemented in code). In OOP, computer programs are designed by making them out of objects that interact with one another. Many of the most widely used programming languages (such as C++, Java, and Python) support object-oriented programming to a greater or lesser degree, typically as part of multiple paradigms in combination with others such as imperative programming and declarative programming. Significant object-oriented languages include Ada, ActionScript, C++, Common Lisp, C#, Dart, Eiffel, Fortran 2003, Haxe, Java, JavaScript, Kotlin, Logo, MATLAB, Objective-C, Object Pascal, Perl, PHP, Python, R, Raku, Ruby, Scala, SIMSCRIPT, Simula, Smalltalk, Swift, Vala and Visual Basic.NET.

Library (computing)
In computing, a library is a collection of System resource, resources that can be leveraged during software development to implement a computer program. Commonly, a library consists of executable code such as compiled function (computer science), functions and Class (computer programming), classes, or a library can be a collection of source code. A resource library may contain data such as images and Text string, text. A library can be used by multiple, independent consumers (programs and other libraries). This differs from resources defined in a program which can usually only be used by that program. When a consumer uses a library resource, it gains the value of the library without having to implement it itself. Libraries encourage software reuse in a Modular programming, modular fashion. Libraries can use other libraries resulting in a hierarchy of libraries in a program. When writing code that uses a library, a programmer only needs to know how to use it not its internal d ...

The GTK Toolkit
''The'' is a grammatical article in English, denoting nouns that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pronoun ''thee' ...

CinePaint
CinePaint is a free and open source computer program for painting and retouching bitmap frames of films. It is a fork of version 1.0.4 of the GNU Image Manipulation Program (GIMP). It enjoyed some success as one of the earliest open source tools developed for feature motion picture visual effects and animation work. The main reason for this adoption over mainline GIMP was its support for high bit depths (greater than 8-bits per channel) which can be required for film work. The mainline GIMP project later added high bit depths in GIMP 2.9.2, released November 2015. It is free software under the GPL-2.0-or-later. In 2018, a post titled "CinePaint 2.0 Making Progress" announced progress, but, , version 2.0 has not been released. Development seems to have stalled entirely, as no new 1.x updates have been released since May 2021. Main features Features that set CinePaint apart from its photo-editing predecessor include the frame manager, onion skinning, and the ability to w ...
