If you are in a Wayland session, replace x11 with wayland. Nine tests are known to fail if Cantrell fonts are not installed. Many tests will fail if ~/.config/gtk-4.0/settings.ini exists and the gtk-modules line is not commented out. On systems with NVIDIA graphics cards, the tests may take significantly longer than the above test time. Now, as the root user: ninja install Command Explanations -Dbroadway-backend=true: This switch enables the HTML5 GDK backend. -Dintrospection=enabled: This switch enables using to generate GIR bindings of this packages. These bindings are required by GNOME. : Use this switch if you have installed and wish to enable support for cloud providers in a file chooser window. : Use this switch if you have installed and wish to use search functionality when running a file chooser. : Use this switch if you have installed and wish to use colord with the CUPS printing backend. : Use this switch if you have installed and wish to generate the man pages. : Use this switch if you have sysprof installed and wish to enable tracing support for GTK4-based applications. : Use this switch if you have installed and wish to build the experimental Vulkan backend. Note that you must have glslc installed if you decide to enable this option. Configuring GTK 4 Config Files ~/.config/gtk-4.0/settings.ini and /usr/share/gtk-4.0/settings.ini ~/.config/gtk-4.0/settings.ini /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 ) and/or a font (), 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: GTK 4 Reference Manual. Contents Installed Programs Installed Libraries Installed Directories gtk4-broadwayd, gtk4-builder-tool, gtk4-demo, gtk4-demo-application, gtk4-encode-symbolic-svg, gtk4-icon-browser, gtk4-launch, gtk4-node-editor, gtk4-print-editor, gtk4-query-settings, gtk4-update-icon-cache, and gtk4-widget-factory libgtk-4.so /usr/include/gtk-4.0, /usr/lib/gtk-4.0, and /usr/share/gtk-4.0 Short Descriptions gtk4-broadwayd provides support for displaying GTK 4 applications in a web browser using HTML5 and web sockets gtk4-broadwayd gtk4-builder-tool performs various operations on GtkBuilder .ui files gtk4-builder-tool gtk4-demo is a simple program that demonstrates some of the tasks that can be done with GTK 4 gtk4-demo gtk4-demo-application is a simple GTK 4 application which is useful for testing gtk4-demo-application 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-encode-symbolic-svg 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-icon-browser 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-launch 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-node-editor gtk4-print-editor is a simple program to demonstrate printing using GTK 4 applications gtk4-print-editor gtk4-query-settings provides a complete listing of all settings related to GTK 4 gtk4-query-settings gtk4-update-icon-cache is an icon theme caching utility that creates mmap()able cache files for icon themes gtk4-update-icon-cache gtk4-widget-factory is a program to view GTK 4 themes and widgets gtk4-widget-factory libgtk-4.so contains functions that provide an API to implement graphical user interfaces libgtk-4.so
