    <summary>Methods for controlling drag and drop handling.</summary>
    <remarks>
      <para>
      Gtk# has a rich set of methods for doing inter-process communication via the drag-and-drop metaphor. Gtk# can do drag-and-drop (DND) via multiple protocols. The currently supported protocols are the Xdnd and Motif protocols. As well as the methods listed here, applications may need to use some facilities provided for <see cref="T:Gtk.Selection" />. Also, the Drag and Drop API makes use of events in the <see cref="T:Gtk.Widget" /> class.
