All Implemented Interfaces:

HasAttachHandlers, HasHandlers, EventListener, HasVisibility, HasWidgets, IsRenderable, IsWidget, RequiresResize, Iterable<Widget>

public class ResizeInterceptor
extends Composite
implements RequiresResize, HasWidgets

Simple wrapper widget that can be used between a ProvidesResize widget (such as a ScrollPanel or LayoutPanel) and other widgets in a Composite panel to allow you to get notifications when it is resized.

Implements HasWidgets so it can contain any number of child widgets (can be used as a replacement for a FlowPanel).

A use case would be where you have a Composite panel containing a SplitLayoutPanel which in turn contains a ScrollPanel containing some elements which you need to base manual positioning logic on. You can then place this ResizeInterceptor inside the ScrollPanel, set a listener implementation on it using setListener(Listener), and implement your repositioning logic in the ResizeInterceptor.Listener.onResize() method.
