GtkSettings 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 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 GtkSettings object with g_object_set(). This should be restricted to special cases though; GtkSettings are not meant as an application configuration facility.

There is one GtkSettings instance per display. It can be obtained with getForDisplay(org.gnome.gdk.Display), but in many cases, it is more convenient to use Widget.getSettings().

Constructor Details

Settings

public Settings(MemorySegment address)

Create a Settings proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Method Details

getType

public static Type getType()

Get the GType of the Settings class

Returns:

the GType

asParent

protected Settings asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class GObject

getDefault

public static Settings getDefault()

Gets the GtkSettings object for the default display, creating it if necessary.

See getForDisplay(org.gnome.gdk.Display).

Returns:

a GtkSettings object. If there is no default display, then returns null.

getForDisplay

public static Settings getForDisplay(Display display)

Gets the GtkSettings object for display, creating it if necessary.

Parameters:

display - a GdkDisplay

Returns:

a GtkSettings object

resetProperty

public void resetProperty(String name)

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.

Parameters:

name - the name of the setting to reset

builder

public static Settings.Builder<? extends Settings.Builder> builder()

A Settings.Builder object constructs a Settings with the specified properties. Use the various set...() methods to set properties, and finish construction with Settings.Builder.build().
