如何在GWT的滚动面板中创建两个或更多列？

Question

通常，滚动面板只有一列。如果我想要两列，我该如何修改我的代码？

ScrollPanel scrollPanel =new ScrollPanel(panel1);
scrollPanel.setSize("200px","100px");
DecoratorPanel decoratorPanel =new DecoratorPanel();
decoratorPanel.add(scrollPanel);
RootPanel.get("gwtContainer").add(panel);
RootPanel.get("gwtContainer").add(decoratorPanel);

您可以滚动网格，FlexTable或LayoutPanel，这样您就可以使用通用滚动条来进行灵活布局。

LayoutPanel lp = new LayoutPanel();
lp.add(whatever1);
lp.add(whatever2);

lp.setWidgetLeftWidth(whatever1, 0, Unit.PCT, 50, Unit.PCT);
lp.setWidgetRightWidth(whatever2, 0, Unit.PCT, 50, Unit.PCT);

ScrollPanel scrollPanel = new ScrollPanel(lp);
scrollPanel.setSize("200px", "100px");

DecoratorPanel decoratorPanel = new DecoratorPanel();
decoratorPanel.add(scrollPanel);

RootPanel.get("gwtContainer").add(decoratorPanel);
