* This tag interface specifies that the implementing widget will call
* {@link RequiresResize#onResize()} on its children whenever their size may
* have changed.
*
* <p>
* With limited exceptions (such as {@link RootLayoutPanel}), widgets that
* implement this interface will also implement {@link RequiresResize}. A typical
* widget will implement {@link RequiresResize#onResize()} like this:
*
* <code>
* public void onResize() {
* for (Widget child : getChildren()) {
* if (child instanceof RequiresResize) {
* ((RequiresResize) child).onResize();
* }
* }
* }
