GtkHeaderBar is similar to a horizontal 'GI.Gtk.Objects.Box.Box'. It allows children to
be placed at the start or the end. In addition, it allows a title and
subtitle to be displayed. The title will be centered with respect to
the width of the box, even if the children at either side take up
different amounts of space. The height of the titlebar will be
set to provide sufficient space for the subtitle, even if none is
currently set. If a subtitle is not needed, the space reservation
can be turned off with 'GI.Gtk.Objects.HeaderBar.headerBarSetHasSubtitle'.

GtkHeaderBar can add typical window frame controls, such as minimize,
maximize and close buttons, or the window icon.

For these reasons, GtkHeaderBar is the natural choice for use as the custom
titlebar widget of a 'GI.Gtk.Objects.Window.Window' (see 'GI.Gtk.Objects.Window.windowSetTitlebar'), as it gives
features typical of titlebars while allowing the addition of child widgets.

the builtin title and subtitle, use the “title” and “subtitle”

{- |
Sets the decoration layout for this header bar, overriding
the 'GI.Gtk.Objects.Settings.Settings':@/gtk-decoration-layout/@ setting.

There can be valid reasons for overriding the setting, such
as a header bar design that does not allow for buttons to take
room on the right, or only offers room for a single close button.
Split header bars are another example for overriding the
setting.

The format of the string is button names, separated by commas.
A colon separates the buttons that should appear on the left
from those on the right. Recognized button names are minimize,
maximize, close, icon (the window icon) and menu (a menu button
for the fallback app menu).

For example, “menu:minimize,maximize,close” specifies a menu
on the left, and minimize, maximize and close buttons on the right.
