GTK+-3.20.9
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-7.10
platform.

Installation of GTK+ 3
![[Note]](../images/note.png)
Note
GTK+ 3 will overwrite
gtk-update-icon-cache from
GTK+-2.24.30 if it is installed. There is
nothing wrong about that assuming that both programs provide same
functionality. If you wish to keep one from GTK+ 2 you can add --enable-gtk2-dependency to the configure command.
Install GTK+ 3 by running the
following commands:
sed -i "/seems to be moved/s/^/#/" build-aux/ltmain.sh &&
./configure --prefix=/usr \
--sysconfdir=/etc \
--enable-broadway-backend \
--enable-x11-backend \
--disable-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.
The accessibility test (six subtests) is known to fail.
To test the results you need a graphical session, then issue
make -k check.
Now, as the root user:
make install
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
sed -i ...
build-aux/ltmain.sh: This sed silences several
useless and annoying warnings generated by libtool.
--enable-broadway-backend:
This switch enables the HTML5 GTK backend.
--enable-x11-backend: This
switch enables the X11 GDK backend.
--{disable,enable}-wayland-backend:
This switch disables or enables the Wayland GDK backend, which is
required for GNOME Wayland
support. Remove it if you have not installed Wayland.
--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. gnome-themes-standard-3.20.2),
an icon theme (such as oxygen-icons5-5.25.0) and/or a
font (such as DejaVu fonts), you can set
your prefences 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.

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 things
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.
