GWT: How to add DockLayoutPanel inside another panel? Not the RootLayoutPanel

问题

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,

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.

See the Using a LayoutPanel without RootLayoutPanel section in http://code.google.com/webtoolkit/doc/latest/DevGuideUiPanels.html#Recipes
