/**
* SECTION:gtkcontainer
* The second type of container can have more than one child; its purpose is to
* manage <emphasis>layout</emphasis>. This means that these containers assign
* sizes and positions to their children. For example, a #GtkHBox arranges its
- * children in a horizontal row, and a #GtkTable arranges the widgets it contains
+ * children in a horizontal row, and a #GtkGrid arranges the widgets it contains
* in a two-dimensional grid.

*
- * Furthermore, in order to ensure correct height-for-width requests it is important
- * to check the input width against the real required minimum width. This can
- * easily be achieved as follows:
- *
- * <programlisting><![CDATA[
- * static void
- * foo_container_get_preferred_height_for_width (GtkWidget *widget, gint for_width,
- * gint *min_height, gint *nat_height)
- * {
- * if (i_am_in_height_for_width_mode)
- * {
- * gint min_width;
- *
- * GTK_WIDGET_GET_CLASS (widget)->get_preferred_width (widget, &min_width, NULL);
- *
- * for_width = MAX (min_width, for_width);

- * else

- * ... fall back on virtual results as mentioned in the previous example ...
- * }
- * }
- * ]]></programlisting>
- *
* Height for width requests are generally implemented in terms of a virtual allocation
* of widgets in the input orientation. Assuming an height-for-width request mode, a container
* would implement the <function>get_preferred_height_for_width()</function> virtual function by first calling
