|
||
* @Short_description: Sharing settings between applications
|
||
* @Title: Settings
|
||
*
|
||
* GtkSettings provide 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. In the absence of
|
||
* an Xsettings manager, 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
|
||
* gtk_settings_get_for_display(), but in many cases, it is more convenient
|
||
* to use gtk_widget_get_settings(). gtk_settings_get_default() returns the
|
||
* GtkSettings instance for the default display.
