<title>Description</title>
<para>The <link
linkend="class-gtklayout"><classname>gtk.Layout</classname></link> is a
simple container widget similar to the <link
linkend="class-gtkfixed"><classname>gtk.Fixed</classname></link> container
widget. Like the <link
linkend="class-gtkfixed"><classname>gtk.Fixed</classname></link> the <link
linkend="class-gtklayout"><classname>gtk.Layout</classname></link> places a
child widget at a specific position within the container. The <link
linkend="class-gtklayout"><classname>gtk.Layout</classname></link> offers
two features beyond the <link
linkend="class-gtkfixed"><classname>gtk.Fixed</classname></link>
widget:</para>
<itemizedlist>
<listitem>
<simpara>a very large width and height for the container - limited
by the size of an unsigned integer.</simpara>
</listitem>
<listitem>
<simpara>horizontal and vertical adjustments can be specified for
use with scrollbars, etc.</simpara>
</listitem>
</itemizedlist>
<para>The <link
linkend="class-gtklayout"><classname>gtk.Layout</classname></link> can also
be drawn on similar to drawing on a <link
linkend="class-gtkdrawingarea"><classname>gtk.DrawingArea</classname></link>.
When handling expose events on a <link
linkend="class-gtklayout"><classname>gtk.Layout</classname></link>, you must
draw to the window specified by the <literal>bin_window</literal> attribute
rather than the widget <literal>window</literal> attribute.</para>
