Pango is a library for laying out and rendering of text, with an emphasis on internationalization. Pango can be used anywhere that text layout is needed, though most of the work on Pango so far has been done in the context of the GTK+ widget toolkit. Pango forms the core of text and font handling for GTK+-2.x.

Pangox was a X backend to pango. It is now obsolete and no longer provided by recent pango releases. pangox-compat provides the functions which were removed.

Gromit-MPX is an on-screen annotation tool that works with any Unix desktop environment under X11 as well as Wayland.

Perl bindings to the 2.x series of the Gtk+ widget set. This module allows you to write graphical user interfaces in a Perlish and object-oriented way, freeing you from the casting and memory management in C, yet remaining very close in spirit to original API.

Guile-Present defines a declarative vocabulary for presentations, together with tools to render presentation documents as SVG or PDF. Guile-Present can be used to make presentations programmatically, but also includes a tools to generate PDF presentations out of Org mode and Texinfo documents.

This package provides a global menu applet for use with desktop panels such as mate-panel and xfce4-panel.

PNMixer is a simple mixer application designed to run in system tray. It integrates nicely into desktop environments that don't have a panel that supports applets and therefore can't run a mixer applet. In particular, it's been used quite a lot with fbpanel and tint2 but should run fine in any system tray.

PNMixer is designed to work on systems that use ALSA for sound management. Any other sound driver like OSS or FFADO are, currently, not supported. There is no official PulseAudio support, at the moment, but it seems that PNMixer behaves quite well anyway when PA is running.

Cairo is a 2D graphics library with support for multiple output devices. Currently supported output targets include the X Window System (via both Xlib and XCB), Quartz, Win32, image buffers, PostScript, PDF, and SVG file output. Experimental backends include OpenGL, BeOS, OS/2, and DirectFB.

Graphene provides graphic types and their relative API; it does not deal with windowing system surfaces, drawing, scene graphs, or input.

GtkDoc is a tool used to extract API documentation from C-code like Doxygen, but handles documentation of GObject (including signals and properties) that makes it very suitable for GTK+ apps and libraries. It uses docbook for intermediate files and can produce html by default and pdf/man-pages with some extra work.

GtkSourceView is a text widget that extends the standard GTK+ text widget GtkTextView. It improves GtkTextView by implementing syntax highlighting and other features typical of a source code editor.

The Assistive Technology Service Provider Interface, core components, is part of the GNOME accessibility project.

Pango is a library for laying out and rendering text, with an emphasis on internationalization. Pango can be used anywhere that text layout is needed, but using Pango in conjunction with Cairo and/or Gtk2 provides a complete solution with high quality text handling and graphics rendering.

Dynamically loaded modules handle text layout for particular combinations of script and font backend. Pango provides a wide selection of modules, including modules for Hebrew, Arabic, Hangul, Thai, and a number of Indic scripts. Virtually all of the world's major scripts are supported.

In addition to the low level layout rendering routines, Pango includes Pango::Layout, a high level driver for laying out entire blocks of text, and routines to assist in editing internationalized text.

Cairomm provides a C++ programming interface to the Cairo 2D graphics library.

Cairo is a 2D graphics library with support for multiple output devices. Currently supported output targets include the X Window System (via both Xlib and XCB), Quartz, Win32, image buffers, PostScript, PDF, and SVG file output. Experimental backends include OpenGL, BeOS, OS/2, and DirectFB.

GooCanvas is a canvas widget for GTK+ that uses the cairo 2D library for drawing.

Pangomm provides a C++ programming interface to the Pango text rendering library.

Ganv is an interactive GTK+ widget for interactive “boxes and lines” or graph-like environments, e.g. modular synths or finite state machine diagrams.

GdkPixbuf-Xlib contains the deprecated API for integrating GdkPixbuf with Xlib data types. This library was originally shipped by gdk-pixbuf, and has since been moved out of the original repository. No newly written code should ever use this library.

ClipIt is a clipboard manager with features such as a history, search thereof, global hotkeys and clipboard item actions. It was forked from Parcellite and adds bugfixes and features.

Libdatrie is an implementation of double-array structure for representing trie. Trie is a kind of digital search tree.

ATKmm is the C++ binding for the ATK library.

This program allows you to display GTK+ dialog boxes from command line or shell scripts. Example of how to use yad can be consulted at https://sourceforge.net/p/yad-dialog/wiki/browse_pages/.

Perl bindings to the 3.x series of the gtk+ toolkit. This module allows you to write graphical user interfaces in a Perlish and object-oriented way, freeing you from the casting and memory management in C, yet remaining very close in spirit to original API.
