GTK+-3.8.4

Introduction to GTK+ 3

The GTK+ 3 package contains the libraries used for creating graphical user interfaces for applications.

This package is known to build and work properly using an LFS-7.4 platform.

Installation of GTK+ 3

[Note]

Note

GTK+ 3 will overwrite gtk-update-icon-cache from GTK+-2.24.20 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:

./configure --prefix=/usr --sysconfdir=/etc &&
make

Three tests are known to fail. To test the results:

make -k check

Now, as the root user:

make install
[Note]

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]

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

--disable-packagekit: switch disables use of PackageKit which isn't needed for BLFS.

rm tests/a11y/pickers.ui: This prevents test being run as it is known to fail.

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 (eg gnome-themes-standard-3.8.4 or an icon theme (such as gnome-icon-theme-3.8.3) you can set your prefences in ~/.config/gtk-3.0/settings.ini. Eg:

mkdir -p ~/.config/gtk-3.0 &&
cat > ~/.config/gtk-3.0/settings.ini << "EOF"
[Settings]
gtk-theme-name = Adwaita
gtk-fallback-icon-theme = gnome
EOF

There are many more themes available at http://gnome-look.org/ and other places.

Once you've settled on themes you like, you can (as the root user) make them the default system wide:

cat > /etc/gtk-3.0/settings.ini << "EOF"
[Settings]
gtk-theme-name = Clearwaita
gtk-fallback-icon-theme = elementary
EOF

Short Descriptions

gtk-launch

launches an application using the given name. The name should match application desktop file name, as residing in /usr/share/application, 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-update-icon-cache

is an icon theme caching utility that creates mmap()able cache files for icon themes.

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-widget-factory

is a program to view GTK+ 3 themes and widgets.

libgailutil-3.so

contains functions that implements 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.
