-/**
- * SECTION:gtkcontainer
- * @Short_description: Base class for widgets which contain other widgets
- * @Title: GtkContainer
- *
- * A GTK user interface is constructed by nesting widgets inside widgets.
- * Container widgets are the inner nodes in the resulting tree of widgets:
- * they contain other widgets. So, for example, you might have a #GtkWindow
- * containing a #GtkFrame containing a #GtkLabel. If you wanted an image instead
- * of a textual label inside the frame, you might replace the #GtkLabel widget
- * with a #GtkImage widget.
- *
- * There are two major kinds of container widgets in GTK. Both are subclasses
- * of the abstract GtkContainer base class.
- *
- * The first type of container widget has a single child widget and derives
- * from #GtkBin. These containers are decorators, which
- * add some kind of functionality to the child. For example, a #GtkButton makes
- * its child into a clickable button; a #GtkFrame draws a frame around its child
- * and a #GtkWindow places its child widget inside a top-level window.
- *
- * The second type of container can have more than one child; its purpose is to
- * manage layout. This means that these containers assign
- * sizes and positions to their children. For example, a horizontal #GtkBox arranges its
- * children in a horizontal row, and a #GtkGrid arranges the widgets it contains
- * in a two-dimensional grid.
- *
- * For implementations of #GtkContainer the virtual method #GtkContainerClass.forall()
- * is always required, since it's used for drawing and other internal operations
- * on the children.
- * If the #GtkContainer implementation expect to have non internal children
- * it's needed to implement both #GtkContainerClass.add() and #GtkContainerClass.remove().
- * If the GtkContainer implementation has internal children, they should be added
- * with gtk_widget_set_parent() on init() and removed with gtk_widget_unparent()
- * in the #GtkWidgetClass.destroy() implementation.
- *
- * See more about implementing custom widgets at https://wiki.gnome.org/HowDoI/CustomWidgets
