Struct gtk4::builders::SettingsBuilder

pub struct SettingsBuilder { /* private fields */ }

A builder-pattern type to construct Settings objects.

Implementations

impl SettingsBuilder

pub fn gtk_alternative_button_order( self, gtk_alternative_button_order: bool ) -> Self

Whether buttons in dialogs should use the alternative button order.

pub fn gtk_alternative_sort_arrows( self, gtk_alternative_sort_arrows: bool ) -> Self

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 gtk_application_prefer_dark_theme( self, gtk_application_prefer_dark_theme: bool ) -> Self

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 gtk_cursor_aspect_ratio(self, gtk_cursor_aspect_ratio: f64) -> Self

The aspect ratio of the text caret.

pub fn gtk_cursor_blink(self, gtk_cursor_blink: bool) -> Self

Whether the cursor should blink.

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

pub fn gtk_cursor_blink_time(self, gtk_cursor_blink_time: i32) -> Self

Length of the cursor blink cycle, in milliseconds.

pub fn gtk_cursor_blink_timeout(self, gtk_cursor_blink_timeout: i32) -> Self

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.

pub fn gtk_cursor_theme_name( self, gtk_cursor_theme_name: impl Into<GString> ) -> Self

Name of the cursor theme to use.

Use None to use the default theme.

pub fn gtk_cursor_theme_size(self, gtk_cursor_theme_size: i32) -> Self

The size to use for cursors.

0 means to use the default size.

pub fn gtk_decoration_layout( self, gtk_decoration_layout: impl Into<GString> ) -> Self

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.

pub fn gtk_dialogs_use_header(self, gtk_dialogs_use_header: bool) -> Self

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.

This setting does not affect custom dialogs using Dialog directly, or message dialogs.

pub fn gtk_dnd_drag_threshold(self, gtk_dnd_drag_threshold: i32) -> Self

The number of pixels the cursor can move before dragging.

pub fn gtk_double_click_distance(self, gtk_double_click_distance: i32) -> Self

The maximum distance allowed between two clicks for them to be considered a double click, in pixels.

pub fn gtk_double_click_time(self, gtk_double_click_time: i32) -> Self

The maximum time to allow between two clicks for them to be considered a double click, in milliseconds.

pub fn gtk_enable_accels(self, gtk_enable_accels: bool) -> Self

Whether menu items should have visible accelerators which can be activated.

pub fn gtk_enable_animations(self, gtk_enable_animations: bool) -> Self

Whether to enable toolkit-wide animations.

pub fn gtk_enable_event_sounds(self, gtk_enable_event_sounds: bool) -> Self

Whether to play any event sounds at all.

See the Sound Theme Specifications for more information on event sounds and sound themes.

GTK itself does not support event sounds, you have to use a loadable module like the one that comes with libcanberra.

pub fn gtk_enable_input_feedback_sounds( self, gtk_enable_input_feedback_sounds: bool ) -> Self

Whether to play event sounds as feedback to user input.

See the Sound Theme Specifications for more information on event sounds and sound themes.

GTK itself does not support event sounds, you have to use a loadable module like the one that comes with libcanberra.

pub fn gtk_enable_primary_paste(self, gtk_enable_primary_paste: bool) -> Self

Whether a middle click on a mouse should paste the ‘PRIMARY’ clipboard content at the cursor location.

pub fn gtk_entry_password_hint_timeout( self, gtk_entry_password_hint_timeout: u32 ) -> Self

How long to show the last input character in hidden entries.

This value is in milliseconds. 0 disables showing the last char. 600 is a good value for enabling it.

pub fn gtk_entry_select_on_focus(self, gtk_entry_select_on_focus: bool) -> Self

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

pub fn gtk_error_bell(self, gtk_error_bell: bool) -> Self

When true, keyboard navigation and other input-related errors will cause a beep.

Since the error bell is implemented using gdk_surface_beep(), the windowing system may offer ways to configure the error bell in many ways, such as flashing the window or similar visual effects.

pub fn gtk_font_name(self, gtk_font_name: impl Into<GString>) -> Self

The default font to use.

GTK uses the family name and size from this string.

pub fn gtk_font_rendering(self, gtk_font_rendering: FontRendering) -> Self

Available on crate feature v4_16 only.

How GTK font rendering is set up.

When set to [enum@Gtk.FontRendering.MANUAL], GTK respects the low-level font-related settings (gtk-hint-font-metrics, gtk-xft-antialias, gtk-xft-hinting, gtk-xft-hintstyle and gtk-xft-rgba) as much as practical.

When set to [enum@Gtk.FontRendering.AUTOMATIC], GTK will consider factors such as screen resolution and scale in deciding how to render fonts.

pub fn gtk_fontconfig_timestamp(self, gtk_fontconfig_timestamp: u32) -> Self

Timestamp of the current fontconfig configuration.

pub fn gtk_hint_font_metrics(self, gtk_hint_font_metrics: bool) -> Self

Available on crate feature v4_6 only.

Whether hinting should be applied to font metrics.

Note that this also turns off subpixel positioning of glyphs, since it conflicts with metrics hinting.

pub fn gtk_icon_theme_name( self, gtk_icon_theme_name: impl Into<GString> ) -> Self

Name of the icon theme to use.

See IconTheme for details about how GTK handles icon themes.

pub fn gtk_im_module(self, gtk_im_module: impl Into<GString>) -> Self

Which IM (input method) module should be used by default.

This is the input method that will be used if the user has not explicitly chosen another input method from the IM context menu. This also can be a colon-separated list of input methods, which GTK will try in turn until it finds one available on the system.

See IMContext.

pub fn gtk_keynav_use_caret(self, gtk_keynav_use_caret: bool) -> Self

Whether GTK should make sure that text can be navigated with a caret, even if it is not editable.

This is useful when using a screen reader.

pub fn gtk_label_select_on_focus(self, gtk_label_select_on_focus: bool) -> Self

Whether to select the contents of a selectable label when it is focused.

pub fn gtk_long_press_time(self, gtk_long_press_time: u32) -> Self

The time for a button or touch press to be considered a “long press”.

See GestureLongPress.

pub fn gtk_overlay_scrolling(self, gtk_overlay_scrolling: bool) -> Self

Whether scrolled windows may use overlaid scrolling indicators.

If this is set to false, scrolled windows will have permanent scrollbars.

pub fn gtk_primary_button_warps_slider( self, gtk_primary_button_warps_slider: bool ) -> Self

If the value of this setting is true, clicking the primary button in a Range trough will move the slider, and hence set the range’s value, to the point that you clicked.

If it is false, a primary click will cause the slider/value to move by the range’s page-size towards the point clicked.

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.

pub fn gtk_print_backends(self, gtk_print_backends: impl Into<GString>) -> Self

A comma-separated list of print backends to use in the print dialog.

Available print backends depend on the GTK installation, and may include “file”, “cups”, “lpr” or “papi”.

pub fn gtk_print_preview_command( self, gtk_print_preview_command: impl Into<GString> ) -> Self

A command to run for displaying the print preview.

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.

pub fn gtk_recent_files_enabled(self, gtk_recent_files_enabled: bool) -> Self

Whether GTK should keep track of items inside the recently used resources list.

If set to false, the list will always be empty.

pub fn gtk_recent_files_max_age(self, gtk_recent_files_max_age: i32) -> Self

The maximum age, in days, of the items inside the recently used resources list.

Items older than this setting will be excised from the list. If set to 0, the list will always be empty; if set to -1, no item will be removed.

pub fn gtk_shell_shows_app_menu(self, gtk_shell_shows_app_menu: bool) -> Self

Set to true if the desktop environment is displaying the app menu, false if the app should display it itself.

pub fn gtk_shell_shows_desktop(self, gtk_shell_shows_desktop: bool) -> Self

Set to true if the desktop environment is displaying the desktop folder, false if not.

pub fn gtk_shell_shows_menubar(self, gtk_shell_shows_menubar: bool) -> Self

Set to true if the desktop environment is displaying the menubar, false if the app should display it itself.

pub fn gtk_show_status_shapes(self, gtk_show_status_shapes: bool) -> Self

Available on crate feature v4_14 only.

When true, widgets like switches include shapes to indicate their on/off state.

pub fn gtk_sound_theme_name( self, gtk_sound_theme_name: impl Into<GString> ) -> Self

The XDG sound theme to use for event sounds.

See the Sound Theme Specifications for more information on event sounds and sound themes.

GTK itself does not support event sounds, you have to use a loadable module like the one that comes with libcanberra.

pub fn gtk_split_cursor(self, gtk_split_cursor: bool) -> Self

Whether two cursors should be displayed for mixed left-to-right and right-to-left text.

pub fn gtk_theme_name(self, gtk_theme_name: impl Into<GString>) -> Self

Name of the theme to load.

See CssProvider for details about how GTK finds the CSS stylesheet for a theme.

pub fn gtk_titlebar_double_click( self, gtk_titlebar_double_click: impl Into<GString> ) -> Self

Determines the action to take when a double-click occurs on the titlebar of client-side decorated windows.

Recognized actions are minimize, toggle-maximize, menu, lower or none.

pub fn gtk_titlebar_middle_click( self, gtk_titlebar_middle_click: impl Into<GString> ) -> Self
