}
var g = this.grid;
var c = g.getgridel();
var csize = c.getsize(true);
var vw = csize.width;

// none?
return;
}

this.innerhd.style.width = (vw) + 'px';
}
} else {
this.el.setsize(csize.width, csize.height);
var hdheight = this.mainhd.getheight();
var vh = csize.height - (hdheight);
this.scroller.setsize(vw, vh);
