java - 调整窗口大小时 GXT ContentPanel 不调整大小

Question

当浏览器调整大小时，我无法调整内容面板的大小。下面的代码渲染内容面板以填充屏幕(所需)，但在浏览器窗口大小更改时不会调整大小。

代码:

 public void onModuleLoad() {
     RootPanel rootPanel = RootPanel.get();
     Viewport viewPort = new Viewport();
     final Layout layout = new FitLayout();
     ContentPanel resultPanel = new ContentPanel();
     resultPanel.setHeading("Result");
     resultPanel.setFrame(true);
     resultPanel.setLayout(layout);
     resultPanel.setScrollMode(Scroll.ALWAYS);
     resultPanel.addButton(new Button("OK"));
     resultPanel.setWidth("100%");
     LayoutContainer page = new LayoutContainer(new RowLayout(Orientation.VERTICAL));
     page.add(resultPanel, new com.extjs.gxt.ui.client.widget.layout.RowData(1, -1));
     viewPort.add(page);

     rootPanel.add(viewPort);
     page.layout();

 }

Answer 1

视口(viewport)也需要一个合适的布局:

viewPort.setLayout(new FitLayout());
