Vaadin拆分布局侦听器-来自客户端的div宽度

在用户停止通过拖放调整 Vaadin 拆分布局的大小后，是否可以获得当前（在客户端）div 宽度？

像这样的东西？

splitLayout.addSplitterDragendListener(new ComponentEventListener<GeneratedVaadinSplitLayout.SplitterDragendEvent<SplitLayout>>() {
        @Override
        public void onComponentEvent(GeneratedVaadinSplitLayout.SplitterDragendEvent<SplitLayout> splitLayoutSplitterDragendEvent) {
            
            Notification.show(div.getWidth()); //it's return width which was defined on compilation

        }
    });
