// Drag, Float or Resize dfrsPart1 (10-12-2004)
// by Vic Phillips http://www.vicsJavaScripts.org.uk

// Application Notes and Customising Variable

// This script allows any element
// to be moved by mousedown and dragging the center of the element
// or resized by mousedown and dragging the edge
//
// On initialisation the positioning of the effected elements
// is changed to 'absolute' but the physical position will not change.

// To initalise the Script
// insert  onload="javascript:dfrsInitialise();"  in the <body> tag.
//
// to allow an element to be moved:   insert attribute  dfrsdrag="yes"   in the opening tag.
// to allow an element to be dragged: insert attribute  dfrsresize="yes" in the opening tag.
// to allow an element to float:      insert attribute  dfrsfloat="yes" in the opening tag.

// to turn float off
// give the element an id, say 'MyId'
// and execute document.getElementById('MyId').dfrsfloat='no';
// to turn float on again
// execute document.getElementById('MyId').dfrsfloat='yes';

// Tested with IE6, NS7, and Mozilla FoxFire.


// Customise
var dfrsEdge=10;  // The element edge to trigger resize
var dfrsZIndex=0; // The base z-Index of the effected elements
