简单的问题....如果我在左侧有一个 StackLayoutPanel,我想单击它在右侧的 DockLayoutPanel 中有一个动态加载的小部件...类似于 GWt 示例 http://gwt.google.com/samples/ Mail/Mail.html .. 单击邮箱下的任何内容都会触发右侧的不同小部件...

我没有使用您正在使用的特定小部件,但这是一般的想法。
public class Index implements EntryPoint {
public void onModuleLoad() {
// the panel that holds the content widgets
final SimplePanel mainPanel = new SimplePanel();
// the panel that holds the links
FlowPanel leftPanel = new FlowPanel();
// the first content widget
final Label oneContent = new Label("one content");
// the second content widget
final Label twoContent = new Label("two content");
// the anchor to load the first content widget when clicked
Anchor one = new Anchor("one menu");
// add the click handler to do the content swap
one.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
// remove any previous content
mainPanel.clear();
// add the first content widget
mainPanel.add(oneContent);
}
});
// the anchor to load the first content widget when clicked
Anchor two = new Anchor("two menu");
// add the click handler to do the content swap
two.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
// remove any previous content
mainPanel.clear();
// add the second content widget
mainPanel.add(twoContent);
}
});
leftPanel.add(one);
leftPanel.add(two);
// add everything to the RootPanel
RootPanel.get().add(leftPanel);
RootPanel.get().add(mainPanel);
}
}
