GTK-4.10.3
Introduction to GTK 4
The GTK 4 package contains
libraries used for creating graphical user interfaces for
applications.
![[Note]](../images/note.png)
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 \
-Dintrospection=enabled \
.. &&
ninja
If you have Gi-DocGen-2023.1 installed and wish to build
the API documentation for this package, issue:
sed "s@'doc'@& / 'gtk-4.10.3'@" -i ../docs/reference/meson.build &&
meson configure -Dgtk_doc=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. On systems with
NVIDIA graphics cards, the tests may take significantly longer than
the advertised test time.
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.
-Dintrospection=enabled:
This switch enables using gobject-introspection-1.76.1 to
generate GIR bindings of this packages. These bindings are required
by GNOME.
-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-3.48.0 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: Allow building this
package without Gi-DocGen-2023.1 installed. If you have
Gi-DocGen-2023.1 installed and you
wish to rebuild and install the API documentation, a meson configure command will
reset this option.
-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-icons5-5.103.0) 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
EOF
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
