        <remarks>Use this method to obtain a System.Drawing.Graphics context from a Gtk drawable.

<para>
   Both pixmaps (<see cref="T:Gdk.Pixmap" />) and windows (<see cref="T:Gdk.Window" />) are drawables (<see cref="T:Gdk.Drawable" />).
</para><para>
The following example shows how to create a custom widget that renders a mesh.  This example overrides the OnExposeEvent method and uses <see cref="N:System.Drawing" /> calls to do the actual drawing:

using System.Drawing;
