Struct gtk4::Settings

pub struct Settings { /* private fields */ }

Settings provides a mechanism to share global settings between applications.

On the X window system, this sharing is realized by an XSettings manager that is usually part of the desktop environment, along with utilities that let the user change these settings.

On Wayland, the settings are obtained either via a settings portal, or by reading desktop settings from Gio::Settings.

On macOS, the settings are obtained from NSUserDefaults.

In the absence of these sharing mechanisms, GTK reads default values for settings from settings.ini files in /etc/gtk-4.0, $XDG_CONFIG_DIRS/gtk-4.0 and $XDG_CONFIG_HOME/gtk-4.0. These files must be valid key files (see GKeyFile), and have a section called Settings. Themes can also provide default values for settings by installing a settings.ini file next to their gtk.css file.

Applications can override system-wide settings by setting the property of the Settings object with g_object_set(). This should be restricted to special cases though; Settings are not meant as an application configuration facility.

There is one Settings instance per display. It can be obtained with for_display(), but in many cases, it is more convenient to use WidgetExt::settings().

Properties

gtk-alternative-button-order

Whether buttons in dialogs should use the alternative button order.

Readable | Writeable

gtk-alternative-sort-arrows

Controls the direction of the sort indicators in sorted list and tree views.

By default an arrow pointing down means the column is sorted in ascending order. When set to true, this order will be inverted.

Readable | Writeable

gtk-application-prefer-dark-theme

Whether the application prefers to use a dark theme.

If a GTK theme includes a dark variant, it will be used instead of the configured theme.

Some applications benefit from minimizing the amount of light pollution that interferes with the content. Good candidates for dark themes are photo and video editors that make the actual content get all the attention and minimize the distraction of the chrome.

Dark themes should not be used for documents, where large spaces are white/light and the dark chrome creates too much contrast (web browser, text editor…).

Readable | Writeable

gtk-cursor-aspect-ratio

The aspect ratio of the text caret.

Readable | Writeable

gtk-cursor-blink

Whether the cursor should blink.

Also see the gtk-cursor-blink-timeout setting, which allows more flexible control over cursor blinking.

Readable | Writeable

gtk-cursor-blink-time

Length of the cursor blink cycle, in milliseconds.

Readable | Writeable

gtk-cursor-blink-timeout

Time after which the cursor stops blinking, in seconds.

The timer is reset after each user interaction.

Setting this to zero has the same effect as setting gtk-cursor-blink to false.

Readable | Writeable

gtk-cursor-theme-name

Name of the cursor theme to use.

Use None to use the default theme.

Readable | Writeable

gtk-cursor-theme-size

The size to use for cursors.

0 means to use the default size.

Readable | Writeable

gtk-decoration-layout

Determines which buttons should be put in the titlebar of client-side decorated windows, and whether they should be placed on the left or right.

The format of the string is button names, separated by commas. A colon separates the buttons that should appear on the left from those on the right. Recognized button names are minimize, maximize, close, icon (the window icon) and menu (a menu button for the fallback app menu).

For example, “menu:minimize,maximize,close” specifies a menu on the left, and minimize, maximize and close buttons on the right.

Note that buttons will only be shown when they are meaningful. E.g. a menu button only appears when the desktop shell does not show the app menu, and a close button only appears on a window that can be closed.

Also note that the setting can be overridden with the decoration-layout property.

Readable | Writeable

gtk-dialogs-use-header

Whether builtin GTK dialogs such as the file chooser, the color chooser or the font chooser will use a header bar at the top to show action widgets, or an action area at the bottom.

gtk-entry-select-on-focus

Whether to select the contents of an entry when it is focused.

Readable | Writeable

gtk-error-bell

GTK uses the family name and size from this string.

Readable | Writeable

gtk-font-rendering

Readable | Writeable

gtk-fontconfig-timestamp

Whichever action you choose for the primary button, the other action will be available by holding Shift and primary-clicking, or clicking the middle mouse button.

The command should contain a f placeholder, which will get replaced by the path to the pdf file. The command may also contain a s placeholder, which will get replaced by the path to a file containing the print settings in the format produced by PrintSettings::to_file().

The preview application is responsible for removing the pdf file and the print settings file when it is done.
