Sets our main struct and passes it to the parent class.
Creates a new gtk.HeaderBar widget.
Retrieves the custom title widget of the header. See HeaderBar.setCustomTitle.

Retrieves the subtitle of the header. See HeaderBar.setSubtitle.
Retrieves the title of the header. See HeaderBar.setTitle.
Adds child to bar, packed with reference to the end of the bar.
Adds child to bar, packed with reference to the start of the bar.
Sets a custom title for the gtk.HeaderBar
Sets the decoration layout for this header bar, overriding the gtk-decoration-layout setting.

Removes all widgets from the container
Adds widget to container. Typically used for simple containers such as gtk.Window, gtk.Frame, or gtk.Button; for more complicated layout containers such as gtk.Box or gtk.Grid, this function will pick default packing parameters that may not be correct. So consider functions such as Box.packStart and Grid.attach as an alternative to Container.add in those cases. A widget may be added to only one container at a time; you can’t place the same widget inside two different containers.
Gets the value of a child property for child and container.
Gets the values of one or more child properties for child and container.
Emits a child-notify signal for the [child property][child-properties] child_property on the child.
Emits a child-notify signal for the [child property][child-properties] specified by pspec on the child.
Sets a child property for child and container.
Sets one or more child properties for child and container.
Returns the type of the children supported by the container.
Invokes callback on each direct child of container, including children that are considered “internal” (implementation details of the container). “Internal” children generally weren’t added by the user of the container, but were added by the container implementation itself.
Invokes callback on each non-internal child of container. See Container.forall for details on what constitutes an “internal” child. For all practical purposes, this function should iterate over precisely those child widgets that were added to the container by the application with explicit add() calls.
Retrieves the border width of the container. See Container.setBorderWidth.
Returns the container’s non-internal children. See Container.forall for details on what constitutes an "internal" child.
Retrieves the focus chain of the container, if one has been set explicitly. If no focus chain has been explicitly set, GTK+ computes the focus chain based on the positions of the children. In that case, GTK+ stores NULL in focusable_widgets and returns FALSE.
Returns the current focus child widget inside container. This is not the currently focused widget. That can be obtained by calling Window.getFocus.
Retrieves the horizontal focus adjustment for the container. See gtk_container_set_focus_hadjustment ().
Retrieves the vertical focus adjustment for the container. See Container.setFocusVadjustment.
Returns a newly created widget path representing all the widget hierarchy from the toplevel down to and including child.
Returns the resize mode for the container. See gtk_container_set_resize_mode ().
When a container receives a call to the draw function, it must send synthetic draw calls to all children that don’t have their own gdk.Windows This function provides a convenient way of doing this. A container, when it receives a call to its draw function, calls Container.propagateDraw once for each child, passing in the cr the container received.
Removes widget from container. widget must be inside container. Note that container will own a reference to widget, and that this may be the last reference held; so removing a widget from its container can destroy that widget. If you want to use widget again, you need to add a reference to it before removing it from a container, using g_object_ref(). If you don’t want to use widget again it’s usually more efficient to simply destroy it directly using Widget.destroy since this will remove it from the container and help break any circular reference count cycles.
Sets the border width of the container.
Sets a focus chain, overriding the one computed automatically by GTK+.
Sets, or unsets if child is NULL, the focused child of container.
Hooks up an adjustment to focus handling in a container, so when a child of the container is focused, the adjustment is scrolled to show that widget. This function sets the horizontal alignment. See ScrolledWindow.getHadjustment for a typical way of obtaining the adjustment and Container.setFocusVadjustment for setting the vertical adjustment.
Hooks up an adjustment to focus handling in a container, so when a child of the container is focused, the adjustment is scrolled to show that widget. This function sets the vertical alignment. See ScrolledWindow.getVadjustment for a typical way of obtaining the adjustment and Container.setFocusHadjustment for setting the horizontal adjustment.
Sets the reallocate_redraws flag of the container to the given value.
Sets the resize mode for the container.
Removes a focus chain explicitly set with Container.setFocusChain.
GtkHeaderBar is similar to a horizontal gtk.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 HeaderBar.setHasSubtitle.
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 gtk.Window (see Window.setTitlebar), as it gives features typical of titlebars while allowing the addition of child widgets.
