## Details

### GtkSettings

    typedef struct _GtkSettings GtkSettings;

### GtkSettingsValue

    typedef struct {
      /* origin should be something like "filename:linenumber" for rc files,
       * or e.g. "XProperty" for other sources
       */
      gchar *origin;

      /* valid types are LONG, DOUBLE and STRING corresponding to the token parsed,
       * or a GSTRING holding an unparsed statement
       */
      GValue value;
    } GtkSettingsValue;

### gtk_settings_get_default ()

    GtkSettings* gtk_settings_get_default       (void);

Gets the GtkSettings object for the default GDK screen, creating it if necessary. See `gtk_settings_get_for_screen()`.
