title: What is an "X11 platform" and can it run on windows?
body: <p>I'm trying to get <a href="https://developer.gnome.org/gtk3/stable/PlugSocket.html" rel="nofollow">GtkPlug and GtkSocket</a> to work on Windows 8, using the <a href="http://www.gtk.org/download/win32.php" rel="nofollow">currently supported GTK3+ windows bundle</a>.</p>
  
  <p>I see in the documentation this note:</p>
  
  <blockquote>
    <p>The GtkPlug and GtkSocket widgets are only available when GTK+ is
    compiled for the X11 platform and GDK_WINDOWING_X11 is defined. They
    can only be used on a GdkX11Display. To use GtkPlug and GtkSocket, you
    need to include the gtk/gtkx.h header.</p>
