Javascript Window Properties

Hello,

Can someone tell me how to include the window properties into this script? Menubar, Toolbar, Resize, Scrollbar, etc.?


<html>
<head>
<title></title>

<script type="text/javascript" language="JavaScript">


<!--


    window.onload = function() {
     

        var width,height,new_x,new_y;


        // New width/height
        width = 640;
        height = 440;

        // Set the new x/y values for the window
        // This will move the window to the center of the screen
        new_x = ((screen.availWidth / 2)- (width / 2));
        new_y = ((screen.availHeight / 2) - (height / 2))

        // Resize the window and move it to the center of the screen
        window.resizeTo(width,height);
        window.moveTo(new_x,new_y);


}
-->
</script>
