GWT：如何在另一个面板中添加DockLayoutPanel？不是RootLayoutPanel [英] GWT: How to add DockLayoutPanel inside another panel? Not the RootLayoutPanel

问题描述

是否可以在除RootLayoutPanel以外的其他面板中添加DockLayoutPanel？
如果是这样，你会怎么做？
我试图将其添加到HTMLPanel中，并且只在DockLayoutPanel的北部显示。
然后我在LayoutPanel内部尝试了它，它再次失败。

我认为它可以用于LayoutPanel，因为RootLayoutPanel是LayoutPanel的一个子类。

欢迎任何答案。
谢谢，

解决方案

DockLayoutPanel 是 RequiresResize 小部件，因此要么将它放入 ProvideResize 小部件（任何所谓的布局面板）或您可以给它一个明确的大小。

Is it possible to add DockLayoutPanel inside another panel other than the RootLayoutPanel? If so, how would you do it? I attempted to add it inside HTMLPanel, and only north of the DockLayoutPanel shows. Then I tried it inside LayoutPanel, it failed again.

I thought it would have work for LayoutPanel because RootLayoutPanel is a subclass of LayoutPanel.

Any answers welcome. Thanks,

解决方案

DockLayoutPanel is a RequiresResize widget, so either you put it inside a ProvidesResize widget (any so called layout panel) or you give it an explicit size.
