GTK-4.8.3
Introduction to GTK 4
The GTK 4 package contains
libraries used for creating graphical user interfaces for
applications.
Note
Development versions of BLFS may not build or run some packages
properly if dependencies have been updated since the most recent
stable versions of the book.

Installation of GTK 4
Install GTK 4 by running the
following commands:
mkdir build &&
cd build &&
meson setup --prefix=/usr \
--buildtype=release \
-Dbroadway-backend=true \
.. &&
ninja
To run the tests, issue: meson test
--setup x11. If you are in a Wayland session,
replace x11 with wayland. A few tests may fail.
Now, as the root
user:
ninja install
Command Explanations
--buildtype=release
:
Specify a buildtype suitable for stable releases of the package, as
the default may produce unoptimized binaries.
-Dbroadway-backend=true
:
This switch enables the HTML5 GDK backend.
-Dcloudproviders=enabled
: Use this
switch if you have libcloudproviders-0.3.1 installed and
wish to enable support for cloud providers in a file chooser
window.
-Dsysprof=enabled
: Use this switch if
you have sysprof-3.46.0 installed and wish to enable
tracing support for GTK4-based applications.
-Dtracker=enabled
: Use this switch if
you have Tracker-3.4.2 installed and wish to use search
functionality when running a file chooser.
-Dcolord=enabled
: Use this switch if
you have colord-1.4.6 installed and wish to use colord
with the CUPS printing backend.
-Dgtk_doc=true
: Use this switch if you
have Gi-DocGen-2023.1 installed and wish to
generate the API reference documentation. Use the sed "s@'doc'@& / 'gtk-4.8.3'@" -i
docs/reference/meson.build before the cd build to make the
documentation install path correct if you will use this switch.
-Dman-pages=true
: Use this switch if
you have docutils-0.19 installed and wish to generate
the man pages.
Configuring GTK 4
Config Files
~/.config/gtk-4.0/settings.ini
and
/usr/share/gtk-4.0/settings.ini
Configuration Information
GTK 4 themes change the way a
GTK 4 application looks. An icon
theme can be used to change the icons that appear on the
application's toolbar. If you have installed a GTK 4 theme (e.g. the Adwaita theme built in
GTK 4), an icon theme (such as
oxygen-icons5-5.101.0) and/or a font
(Dejavu fonts), you can set your
preferences in ~/.config/gtk-4.0/settings.ini
, or the default
system-wide configuration file (as the root
user), in /usr/share/gtk-4.0/settings.ini
. For the local
user, an example is:
mkdir -pv ~/.config/gtk-4.0
cat > ~/.config/gtk-4.0/settings.ini << "EOF"
[Settings]
gtk-theme-name = Adwaita
gtk-icon-theme-name = oxygen
gtk-font-name = DejaVu Sans 12
gtk-cursor-theme-size = 18
gtk-xft-antialias = 1
gtk-xft-hinting = 1
gtk-xft-hintstyle = hintslight
gtk-xft-rgba = rgb
gtk-cursor-theme-name = Adwaita

There are many settings keys, some with default values. You can
find them at Settings:

Short Descriptions
gtk4-broadwayd
|
provides support for displaying GTK 4 applications in a
web browser using HTML5 and web sockets
|
gtk4-builder-tool
|
performs various operations on GtkBuilder .ui files
|
gtk4-demo
|
is a simple program that demonstrates some of the tasks
that can be done with GTK 4
|
gtk4-demo-application
|
is a simple GTK 4 application which is useful for testing
|
gtk4-encode-symbolic-svg
|
converts symbolic SVG icons into special PNG files. GTK 4
can load and recolor these PNGs, just like original SVGs,
but loading them is much faster
|
gtk4-icon-browser
|
is a utility to explore the icons in the current icon
theme. It shows icons in various sizes, their symbolic
variants when available, as well as a description of the
icon and its context
|
gtk4-launch
|
launches an application using the given name. The name
should match the application .desktop file name (as seen
in /usr/share/applications ), with or
without the '.desktop' extension
|
gtk4-node-editor
|
is a utility to show and edit render node files. Such
render node files can be obtained e.g. from the GTK
inspector
|
gtk4-print-editor
|
is a simple program to demonstrate printing using GTK 4
applications
|
gtk4-query-settings
|
provides a complete listing of all settings related to
GTK 4
|
gtk4-update-icon-cache
|
is an icon theme caching utility that creates mmap()able
cache files for icon themes
|
gtk4-widget-factory
|
is a program to view GTK 4 themes and widgets
|
libgtk-4.so
|
contains functions that provide an API to implement
graphical user interfaces
