+ * toolbar items
+ * @Title: GtkSeparatorToolItem
+ * @See_also: #GtkToolbar, #GtkRadioToolButton
+ *
+ * A #GtkSeparatorToolItem is a #GtkToolItem that separates groups of other
+ * #GtkToolItems. Depending on the theme, a #GtkSeparatorToolItem will
+ * often look like a vertical line on horizontally docked toolbars.
+ *
+ * If the #GtkToolbar child property "expand" is %TRUE and the property
+ * #GtkSeparatorToolItem:draw is %FALSE, a #GtkSeparatorToolItem will act as
+ * a "spring" that forces other items to the ends of the toolbar.
+ *
+ * Use gtk_separator_tool_item_new() to create a new #GtkSeparatorToolItem.
