Contains back-ends to, Broadway , and and relies on for the rendering. Its new SceneGraph is work-in-progress.The GTK contains a set of graphical control elements , version 3.22.16 contains 186 active and 36 deprecated widgets. GTK is an written in the programming language; it uses, that is the object system, for the object orientation. While GTK is mainly for windowing systems based on and, it works on other platforms, including (interfaced with the ), and (interfaced with ). There is also an back-end named Broadway.GTK can be configured to change the look of the widgets drawn; this is done using different display engines. Several display engines exist which try to emulate the look of the native widgets on the platform in use.Starting with version 2.8, released in 2005, GTK began the transition to using to most of its graphical control elements. Since GTK version 3.0, all the rendering is done using Cairo.

On 2018-Jan-26 at Matthias Clasen gave an overview of the current state of GTK 4 development, including a high-level explanation of how rendering and input worked in GTK 3, what changes are being made in GTK 4 (3.90), and why. In February it was announced that GTK 4 will drop the “+” from the project's name. GIMP Drawing Kit (GDK).

At the end of the book, we discuss how the creation of GUIs can be made simpler with the Glade XML library and the GTK Designer. The reader is expected to have knowledge of the Python programming language. The following books are recommended for beginners: Non-Programmer's Tutorial for Python 2.6; Non-Programmer's Tutorial for Python 3.
Main article:GSK is the rendering and scene graph API for GTK. GSK lies between the graphical control elements (widgets) and the rendering. GSK was finally merged into GTK+ version 3.90 released March 2017.GSK is found in the directory.GtkInspector GtkInspector was introduced with version 3.14.GtkInspector can only be invoked after installing the development package /.GUI designers There are several for GTK. The following projects are active as of July 2011:., supports, which is a GTK built-in GUI description format., GUI builder for the GTK toolkit written in Python. Crow Designer, relies on its own GuiXml format and GuiLoader library., part of, oriented toward.GtkBuilder GtkBuilder allows user interfaces to be designed without writing code. The interface is described in an (XML) file, which is then loaded at runtime and the objects created automatically.
The Glade Interface Designer allows creation of the user interface in a what you see is what you get manner. The description of the user interface is independent from the programming language being used.Language bindings.Written in,WebsiteGtk# is a set of bindings for the GTK (GUI) and assorted. The library facilitates building graphical GNOME applications using or any other compliant (CLR).
Gtk# is an event-driven system like any other modern windowing library where every allows associating handler methods, which get called when certain events occur.Applications built using Gtk# will run on many platforms including,. The Mono packages for Windows include GTK, Gtk# and a native theme to make applications look like native Windows applications. Starting with Mono 1.9, running Gtk# applications on macOS no longer requires running an server.can be used with the Glade# bindings to easily design GUI applications. A GUI designer named is integrated with the (IDE).In addition to support the standard GTK/GNOME stack of development tools, the gtk-dotnet.dll assembly provides a bridge to consume functionality available on the.NET stack.
At this point this includes the functionality to use System.Drawing to draw on a widget.GtkSourceView. Main article:For there is, 'source code editing widget'.GtkSourceView is maintained separately from GTK as a library:. There are plans to rename to gsv.GtkSpell GtkSpell is a distinct library separate to GTK. GtkSpell depends on GTK. Enchant is a wrapper for ispell, etc, the actual engine/software.GtkSpell uses GTK's GtkTextView widget, to highlight misspelled words and offer replacement.Development GTK is mainly developed by, which also develops the GNOME Development Platform and the GNOME Desktop Environment.GTK development is loosely managed.
Discussion chiefly occurs on several public mailing lists. GNOME developers and users gather at an annual GNOME Users And Developers European Conference meeting to discuss GNOME's current state and future direction. GNOME incorporates standards and programs from to better with other desktops.GTK is mainly written in.
Many.On September 1, 2016 a post on the GTK development blog denoted, among other things, the future numbering scheme of GTK. GTK version 3.22 from autumn 2016 shall be the last 3.x release. After that all resources will move to the GTK 4 development series with the version names 3.90, 3.92, etc. Even as the 4.x series enters development, notable applications still use GTK 2.x and have not been ported to 3.22. Regarding the future of legacy, there is no collective project to port GTK 2.x software to 3.22.Build automation In former times GTK (and GNOME, GLib, etc.) utilized the (named Autotools) as the system of choice.Since 14 Aug 2017, the master branch of GTK builds with, and the Autotools build system files have been dropped. Criticism.
See also:The most common criticism of GTK is the lack of backward-compatibility in major updates, most notably in the (API) and theming.The compatibility breaks between minor releases during the GTK 3.x development cycle was explained by Benjamin Otte as due to strong pressures to innovate, such as providing the features modern users expect and supporting the increasingly influential. With the release of GTK 4, the pressure from the need to innovate will have been released and the balance between stability and innovation will tip toward stability. Similarly, recent changes to theming are specifically intended to improve and stabilise that part of the API, meaning some investment now should be rewarded later. Dirk Hohndel, codeveloper of and member of 's Open-Source Technology Center, criticized the GTK developers for being abrasive and ignoring most community requests. Hong Jen Yee, developer of (the GTK version of which will be dropped and all efforts focused on the ), expressed disdain for version 3 of the GTK toolkit's radical API changes and increased memory usage, and ported (PCManFM) to.
PCManFM is being developed with a GTK and with a Qt backend at the same time. The music player moved to Qt in version 3.6. The reasons stated by the developers for this include a transition to client-side window decorations, which they claim cause the application to look '-y and out of place.' . has switched to Qt due to not having a good experience with GTK's cross-platform support.Use.

Want to improve this question? So it's for Stack Overflow.Closed 3 years ago.I am new to gtk and gnome programming and like to study GTK+ 3.0 and Gnome 3 programming. Since both of these are recent APIs, I can't find a good tutorial or blog post about these topics. The books I found on GTK+ or GNOME programming are very old ones. So I decided to start with the latest gtk tutorial at which currently happened to be about GTK+ 2.90.7.I need your help to find any tutorial or blogs or any book which cover GTK+ 3.0 or GNOME 3 programming topics. Would you please share any links that you know about these topics and thank you in advance.

Well, you need to start looking. Second, what was said before is kinda right, there are books about Gtk+ 2.x and you could apply almost everything you learn to Gtk+ 3.x programming. I started by using Gtk+ 2.x and a few time later Gtk+ 3.x went out.
I changed to the new version, migrated my old code, and that was how I learn to use Gtk+ 3.x, although have to say that is a process of always learning with Gtk/Glib based programming.My recommendation: Learn Gtk+ 2.x there's some books, and some tutorials around. And your other tool, main tool to is to read Gnome Project code, code from nautilus, gnome-control-center, gnome-utils, etc., almost everything basic you want to make your app do, there's already done by some Gnome module.
Why don't you start with GTK+ 2.x? I used GTK+ 2.x for my project and changed it to GTK3+ lately. Most changes are object fields which became private and now have to be accessed via methods. Another big change in GTK3+ is the depreacation of GdkGC. Instead of GdkGC you now have to use Cairo, but cairo is already available in GTK 2.x. In my opinion moving from GTK+ 2.x to GTK3+ at a latter stadium is not a big issue.
And since GTK3+ is still pretty new it is not fully supported everywhere. I.e: the latest LTS Ubuntu is 10.10 which does not run GTK3+. Neither is the GTK3+ for Windows fully supported yet.
