What is GTK+
============

GTK+ is a multi-platform toolkit for creating graphical user interfaces.
Offering a comprehensive set of widgets as well as facilities for creating
your own widgets, GTK+ is suitable for projects ranging from small one-off
tools to complete application suites.

GTK+ has been designed from the ground up to support a range of languages,
not only C/C++. Using GTK+ from languages such as Python, Vala and JavaScript
(especially in combination with gobject-introspection and the Glade GUI builder)
provides an effective method of rapid application development.

GTK+ is free software and part of the GNU Project. However, the licensing terms
for GTK+, the GNU LGPL, allow it to be used by all developers, including those
developing proprietary software, without any license fees or royalties.

Since its origins as the toolkit for the GNU Image Manipulation Program (GIMP),
GTK+ has been used in a wide range of software. Notably, GTK+ is the foundation
of the GNOME desktop.


What's new in 3.16
==================

Major new features include:

* GDK supports rendering windows using OpenGL; currently
  this is implemented for X11 and Wayland using libepoxy

* GtkGLArea is a new widget for rendering with OpenGL

* GtkStackSidebar is a new controller for GtkStack that looks
  like a sidebar

* GtkModelButton is a button that can be used with a GAction as 'model'

* GtkPopoverMenu is a GtkPopover subclass that makes it easy to
  create menu-like popovers

* Scrolling has been overhauled
 - Scrollbars can be overlayed
 - There is a 'scrolled off' indication
 - Signals ::edge-reached and ::edge-overshot have been added
 - The new GTK_POLICY_EXTERNAL policy allows scrolling without
   a visible scrollbar

* An experimental Mir backend has been added

* Deprecations and removals:
  gdk_window_set_static_gravities, gdk_window_set_composited,
  gtk_style_context_get_background_color, gtk_style_context_get_border_color,
  gtk_settings_set_string/long/double_property, gtk_settings_install_property,
  GtkStyleProperties, gdk_cursor_new, gdk_*_libgtk_only,
  GtkCellRendererPixbuf::follow-state
