gwt - 如何获取 SplitLayoutPanel 的 Central Widget？

Question

看这个代码；

SplitLayoutPanel splitLayoutPanel=new SplitLayoutPanel();
splitLayoutPanel.addWest(new Label("west"), 200);
splitLayoutPanel.add(new Label("center"));

然后

Label myWestLb= (Label)splitLayoutPanel.getWidget(0); //this code is ok, no problem

Label myCentralLb= (Label)splitLayoutPanel.getWidget(1); //this code got error

有谁知道如何获取添加到 SplitLayoutPanel 中心的 Widget？

有一种方法。它被称为 getCenter() :)。
