Now, as the root user: ninja install 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 -Dbroadway_backend=true: This switch enables the HTML5 GTK backend. -Dman=true: This switch allows generating manual pages. -Dgtk_doc=true: This switch enables building documentation. It requires . -Dtracker3=true: This switch enables the search function based on Tracker 3 in the GTK+-3 file chooser dialog. It requires . ~/.config/gtk-3.0/settings.ini and /etc/gtk-3.0/settings.ini ~/.config/gtk-3.0/settings.ini /etc/gtk-3.0/settings.ini 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 ) and/or a font (), 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 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 Installed Programs Installed Libraries Installed Directories broadwayd, gtk3-demo, gtk3-demo-application, gtk3-icon-browser, gtk3-widget-factory, gtk-builder-tool, gtk-encode-symbolic-svg, gtk-launch, gtk-query-immodules-3.0, gtk-query-settings, and gtk-update-icon-cache libgailutil-3.so, libgdk-3.so, and libgtk-3.so /etc/gtk-3.0, /usr/include/{gail,gtk}-3.0, /usr/{lib,share}/gtk-3.0, and /usr/share/themes/{Default,Emacs}/gtk-3.0 Short Descriptions broadwayd provides support for displaying GTK+ 3 applications in a web browser, using HTML5 and web sockets broadwayd gtk3-demo is a simple program that demonstrates some of the tasks that can be done with GTK+ 3 gtk3-demo gtk3-demo-application is a simple GTK+ 3 application gtk3-demo-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-icon-browser gtk3-widget-factory is a program to view GTK+ 3 themes and widgets gtk3-widget-factory gtk-builder-tool performs various operations on GtkBuilder .ui files gtk-builder-tool 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-encode-symbolic-svg 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-launch 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-immodules-3.0 gtk-query-settings provides a complete listing of all settings related to GTK+ 3 gtk-query-settings gtk-update-icon-cache is an icon theme caching utility that creates mmap()able cache files for icon themes gtk-update-icon-cache libgailutil-3.so contains functions that implement the accessibility interfaces defined by the GNOME Accessibility Toolkit libgailutil-3.so libgdk-3.so contains functions that act as a wrapper around the low-level drawing and windowing functions provided by the underlying graphics system libgdk-3.so libgtk-3.so contains functions that provide an API to implement graphical user interfaces libgtk-3.so
