37/**
* SECTION:ctkheaderbar
* @Short_description: A box with a centered child
* @Title: CtkHeaderBar
* @See_also: #CtkBox, #CtkActionBar
*
* CtkHeaderBar is similar to a horizontal #CtkBox. 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 ctk_header_bar_set_has_subtitle().
*
* CtkHeaderBar can add typical window frame controls, such as minimize,
* maximize and close buttons, or the window icon.
*
* For these reasons, CtkHeaderBar is the natural choice for use as the custom
* titlebar widget of a #CtkWindow (see ctk_window_set_titlebar()), as it gives
* features typical of titlebars while allowing the addition of child widgets.
