GTK+-3.24.22
Introduction to GTK+ 3
The GTK+ 3 package contains
libraries used for creating graphical user interfaces for
applications.
This package is known to build and work properly using an LFS-10.0
platform.

Installation of GTK+ 3
Install GTK+ 3 by running the
following commands:
./configure --prefix=/usr \
--sysconfdir=/etc \
--enable-broadway-backend \
--enable-x11-backend \
--enable-wayland-backend &&
make
Some tests fail if /usr/share/glib-2.0/schemas/gschemas.compiled is
not found. If you wish to run the test suite, create (or update)
the file using the following command as the root user: glib-compile-schemas
/usr/share/glib-2.0/schemas.
To test the results you need a graphical session, then issue
make check. The
accessibility portion of the test suite (7 tests) is known to fail.
Now, as the root user:
make install
![[Note]](../images/note.png)
Note
If you installed the package on to your system using a
“DESTDIR” method, an important file
was not installed and must be copied and/or generated. Generate
it using the following command as the root user:
gtk-query-immodules-3.0 --update-cache
Note
If you installed the package to your system using a “DESTDIR”
method, /usr/share/glib-2.0/schemas/gschemas.compiled
was not updated/created. Create (or update) the file using the
following command as the root
user:
glib-compile-schemas /usr/share/glib-2.0/schemas
Command Explanations
--enable-broadway-backend:
This switch enables the HTML5 GTK backend.
--enable-x11-backend: This
switch enables the X11 GDK backend.
--enable-wayland-backend:
This switch enables the Wayland GDK backend. Replace with
--disable-wayland-backend if you do not
have Wayland-1.18.0 and wayland-protocols-1.20 or you do not
wish to build GNOME with Wayland
support. Other changes may be needed to allow the build to complete
without the wayland backend enabled. Note that a previous
installation of gtk+3 built with wayland will interfere with
installation without wayland. If this is desired, remove
/usr/lib/libgtk-3* before installation.
--enable-gtk-doc: Use this parameter if
GTK-Doc is installed and you wish
to rebuild and install the API documentation.
Configuring GTK+ 3
Config Files
~/.config/gtk-3.0/settings.ini and
/etc/gtk-3.0/settings.ini
Configuration Information
GTK+ 3 themes change the way a
GTK+ 3 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+ 3 theme (e.g. the Adwaita theme built
in GTK+ 3), an icon theme (such
as oxygen-icons5-5.73.0) and/or a font
(Dejavu fonts), you can set your
preferences in ~/.config/gtk-3.0/settings.ini, or the default
system wide configuration file (as the root user), in /etc/gtk-3.0/settings.ini. For the local user
an example is:
mkdir -vp ~/.config/gtk-3.0
cat > ~/.config/gtk-3.0/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-toolbar-style = GTK_TOOLBAR_BOTH_HORIZ
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:
GTK+ 3 Reference Manual. There are many more themes available
at http://gnome-look.org/ and other
places.
As part of GTK+-3.0's redesign, the scroll bar buttons are no
longer visible on the scrollbar in many applications. If this
functionality is desired, modify the gtk.css file and restore them using the
following command:
cat > ~/.config/gtk-3.0/gtk.css << "EOF"
* {
-GtkScrollbar-has-backward-stepper: 1;
-GtkScrollbar-has-forward-stepper: 1;
}
EOF

Short Descriptions
|
broadwayd
|
provides support for displaying GTK+ 3 applications in a web
browser, using HTML5 and web sockets.
|
|
gtk3-demo
|
is a simple program that demonstrates some of the tasks
that can be done with GTK+
3
|
|
gtk3-demo-application
|
is a simple GTK+ 3
application.
|
|
gtk3-icon-browser
|
is a utility to explore the icons in the current icon
theme. It shows icons in various sizes, their symbolic
variants where available, as well as a description of the
icon and its context.
|
|
gtk3-widget-factory
|
is a program to view GTK+
3 themes and widgets.
|
|
gtk-builder-tool
|
can perform various operations on GtkBuilder .ui files.
|
|
gtk-encode-symbolic-svg
|
converts symbolic svg icons into specially prepared png
files. GTK+ 3 can load
and recolor these pngs, just like original svgs, but
loading them is much faster.
|
|
gtk-launch
|
launches an application using the given name. The name
should match the application desktop file name, as
residing in /usr/share/applications, with or
without the '.desktop' suffix.
|
|
gtk-query-immodules-3.0
|
collects information about loadable input method modules
for GTK+ 3 and writes it
to the default cache file location, or to standard
output.
|
|
gtk-query-settings
|
provides a complete listing of all settings related to
GTK+ 3
|
|
gtk-update-icon-cache
|
is an icon theme caching utility that creates mmap()able
cache files for icon themes.
|
|
libgailutil-3.so
|
contains functions that implement the accessibility
interfaces defined by the GNOME Accessibility Toolkit.
|
|
libgdk-3.so
|
contains functions that act as a wrapper around the
low-level drawing and windowing functions provided by the
underlying graphics system.
|
|
libgtk-3.so
|
contains functions that provide an API to implement
graphical user interfaces.
