* @Short_description: A toolbar item that separates groups of other
* 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.
*
* # CSS nodes
*
* GtkSeparatorToolItem has a single CSS node with name separator.
