/**
|
||
* GtkSettings:
|
||
*
|
||
* `GtkSettings` provides a mechanism to share global settings between
|
||
* applications.
|
||
*
|
||
* On the X window system, this sharing is realized by an
|
||
* [XSettings](http://www.freedesktop.org/wiki/Specifications/xsettings-spec)
|
||
* 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 `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
|
||
* [func@Gtk.Settings.get_for_display], but in many cases, it is more
|
||
* convenient to use [method@Gtk.Widget.get_settings].
