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.

GTKmm is the official C++ interface for the popular GUI library GTK+. Highlights include typesafe callbacks, and a comprehensive set of widgets that are easily extensible via inheritance. You can create user interfaces either in code or with the Glade User Interface designer, using libglademm. There's extensive documentation, including API reference and a tutorial.

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.

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/.

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.

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.

Layer Shell is a Wayland protocol for desktop shell components, such as panels, notifications and wallpapers. It can be used to anchor windows to a corner or edge of the output, or stretch them across the entire output. It supports all Layer Shell features including popups and popovers.

Volume Icon is a volume indicator and control applet for the Advanced Linux Sound Architecture. It sits in the system tray, independent of your desktop environment, and supports global key bindings.

GNU Spread Sheet Widget is a library for Gtk+ which provides a widget for viewing and manipulating 2 dimensional tabular data in a manner similar to many popular spread sheet programs.

Cairo::GObject registers Cairo's types with Glib's type systems, so that they can be used normally in signals and properties.

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

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

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

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.

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

Libpanel provides a library to create IDE-like applications using GTK and libadwaita. It has widgets for panels, docks, columns and grids of pages. Primarily, its design and implementation focus around the GNOME Builder and Drafting projects.

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.

GtkSheet is a matrix widget for GTK+. It consists of an scrollable grid of cells where you can allocate text. Cell contents can be edited interactively through a specially designed entry, GtkItemEntry. It is also a container subclass, allowing you to display buttons, images and any other widget in it. You can also set many attributes such as border, foreground and background colors, text justification and more.

GdkPixbuf is a library that loads image data in various formats and stores it as linear buffers in memory. The buffers can then be scaled, composited, modified, saved, or rendered.

gtksourceviewmm is a portable C++ library that extends the standard GTK+ framework for multiline text editing with support for configurable syntax highlighting, unlimited undo/redo, search and replace, a completion framework, printing and other features typical of a source code editor.

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.
