HeaderBarRef

public struct HeaderBarRef : HeaderBarProtocol, GWeakCapturing

GtkHeaderBar is similar to a horizontal GtkBox. 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 gtk_header_bar_set_has_subtitle().

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 GtkWindow (see gtk_window_set_titlebar()), as it gives features typical of titlebars while allowing the addition of child widgets.

The HeaderBarRef type acts as a lightweight Swift reference to an underlying GtkHeaderBar instance. It exposes methods that can operate on this data type through HeaderBarProtocol conformance. Use HeaderBarRef only as an unowned reference to an existing GtkHeaderBar instance.
