Text of the page (random words):
gtk documentation sections user interface core libraries older versions gtk documentation user interface gtk gtk is the primary library used to construct user interfaces it provides user interface controls and signal callbacks to respond to user actions gtk api reference gsk an intermediate layer which provides a rendering api implemented using cairo opengl or vulkan gsk api reference gdk an intermediate layer which isolates gtk from the details of the windowing system gdk api reference pango pango is the core text and font handling library used in gtk applications it has extensive support for the different writing systems used throughout the world pango api reference gdkpixbuf gdkpixbuf is a library for image loading and manipulation gdkpixbuf api reference cairo cairo is a 2d graphics library with support for multiple output devices it is designed to produce consistent high quality output on all media cairo api reference core libraries glib glib provides the core application building blocks for libraries and applications written in c it provides common data types used in gtk the main loop implementation and a large set of utility functions for strings and general portability across different platforms glib api reference glib unix specific api reference glib windows specific api reference gobject gobject provides the object system used by gtk gobject api reference gio gio provides a portable modern and easy to use file system abstraction api for accessing local and remote files a set of low and high level abstractions over the dbus ipc specification an application settings api portable networking abstractions and additional utilities for writing asynchronous operations without blocking the user interface of your application gio api reference gio unix specific api reference gio windows specific api reference girepository girepository provides access to introspected api bindings built using gobject introspection girepository api reference older versions gtk 3 the gtk 3 toolkit gtk 3 api reference gdk 3 the gtk 3 windowing system abstraction gdk 3 api reference atk the accessibility toolkit used by gtk 3 atk api reference
