Layout
layoutWidget is called immediately after WidgetBuilder.buildWidget and WidgetProcessor.processWidget, and before the next widget is generated. An alternate design would be to 'collect' all widgets generated by buildWidget and processWidget, then iterate over them separately for the layout. If you prefer this approach, you can simulate it by having layoutWidget do nothing but 'remember' each widget, then iterate over them in endContainerLayout (see the AdvancedLayout interface). However not all UI frameworks allow this approach, because they do not suport widgets being instantiated independent of a layout, nor moved between layouts (e.g. SWT)

true
if the given widget should be ignored, and no section heading
created for it. For example, the widget might be an empty Stub widget.
Subclasses should override this method and return true
if the widget is some
other kind of ignored component (eg. HtmlInputHidden
).
