Un vecchio esperimento non proseguito...
codice:
<HEAD>
<script>
var spFlag = false;
var osx = 0;
var nsx = 0;

function spMove(o) {
	if (spFlag ){
		nsx = event.screenX;
		ll = parseInt(document.getElementById(o).style.width) + nsx - osx;
		if(ll >= 0) {
			document.getElementById(o).style.width = "" + ll + "px"; 
			osx = nsx;
		}
	}
}                                                   
                                                                
function spDown(o) {
	document.body.style.cursor = 'move';
	spFlag = true;
	osx = event.screenX;
}

function spUp(o) {
	document.body.style.cursor = 'auto';
	spFlag = false;
}

document.ondragstart   = new Function("return false;");

</script>
</HEAD>
