1 /* Header Bar
2 *
3 * GtkHeaderBar is a container that is suitable for implementing
4 * window titlebars. One of its features is that it can position
5 * a title (and optional subtitle) centered with regard to the
6 * full width, regardless of variable-width content at the left
7 * or right.
8 *
9 * It is commonly used with gtk_window_set_titlebar()
