Fullscreen Initialization

If you want to carry out fullscreen initialization - create a new dhtmlXLayoutObject with the following arguments:

var dhxLayout = new dhtmlXLayoutObject(document.body, "3L", "dhx_black");

The first argument in dhtmlXLayoutObject() specifies fullscreen initialization.
The second argument - the name of a layout's pattern.
The third argument - the name of a layout's skin. It's optional. The default value - 'dhx_skyblue'.

Here is the recommended code for the fullscreen initialization:

<html>
  <head>
      ...
      <style>
            html, body {
                      width: 100%;
                      height: 100%;
                      margin: 0px;
                      overflow: hidden;
              }
      </style>
      <script>
              var dhxLayout;
              dhtmlxEvent(window,"load",function(){
                  dhxLayout = new dhtmlXLayoutObject(document.body,"...");
              }
       </script>
  </head>
  <body>
      ...
  </body>
</html>
