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