Interface ProvidesResize

All Known Implementing Classes:
  CellBrowser, CustomScrollPanel, DeckLayoutPanel, DockLayoutPanel, LayoutPanel, ResizeLayoutPanel, RootLayoutPanel, ScrollPanel, SimpleLayoutPanel, SplitLayoutPanel, StackLayoutPanel, TabLayoutPanel

    public interface ProvidesResize

This tag interface specifies that the implementing widget will call `RequiresResize.onResize()` on its children whenever their size may have changed.

With limited exceptions (such as `RootLayoutPanel`), widgets that implement this interface will also implement `RequiresResize`. A typical widget will implement `RequiresResize.onResize()` like this: `public void onResize() { for (Widget child : getChildren()) { if (child instanceof RequiresResize) { ((RequiresResize) child).onResize(); } } }`
