Struct gtk4::Settings

#[repr(transparent)]
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 DConf.

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().

Implements

glib::ObjectExt, StyleProviderExt

Implementations

impl Settings

pub fn builder() -> SettingsBuilder

Creates a new builder-pattern struct instance to construct Settings objects.

This method returns an instance of SettingsBuilder which can be used to create Settings objects.

pub fn reset_property(&self, name: &str)

Undoes the effect of calling g_object_set() to install an application-specific value for a setting.

After this call, the setting will again follow the session-wide value for this setting.

name

the name of the setting to reset

pub fn is_gtk_alternative_button_order(&self) -> bool

Whether buttons in dialogs should use the alternative button order.

pub fn set_gtk_alternative_button_order(
    &self,
    gtk_alternative_button_order: bool
)

Whether buttons in dialogs should use the alternative button order.

pub fn is_gtk_alternative_sort_arrows(&self) -> bool

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.

pub fn set_gtk_alternative_sort_arrows(&self, gtk_alternative_sort_arrows: bool)

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.

pub fn is_gtk_application_prefer_dark_theme(&self) -> bool

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…).

pub fn set_gtk_application_prefer_dark_theme(
    &self,
    gtk_application_prefer_dark_theme: bool
)

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…).

pub fn gtk_cursor_aspect_ratio(&self) -> f64

pub fn set_gtk_cursor_aspect_ratio(&self, gtk_cursor_aspect_ratio: f64)

The aspect ratio of the text caret.

pub fn is_gtk_cursor_blink(&self) -> bool

Whether the cursor should blink.

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

Length of the cursor blink cycle, in milliseconds.

pub fn gtk_cursor_blink_timeout(&self) -> i32

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 property::Settings::gtk-cursor-blink to false.

pub fn set_gtk_cursor_blink_timeout(&self, gtk_cursor_blink_timeout: i32)

Time after which the cursor stops blinking, in seconds.

The timer is reset after each user interaction.

0 means to use the default size.

pub fn gtk_decoration_layout(&self) -> Option<GString>

Determines which buttons should be put in the titlebar of client-side decorated windows, and whether they should be placed at the left of 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 property::HeaderBar::decoration-layout property.
