All Implemented Interfaces:

public class RootLayoutPanel
extends LayoutPanel

A singleton implementation of LayoutPanel that always attaches itself to the document body (i.e. RootPanel.get()).

This panel automatically calls RequiresResize.onResize() on itself when initially created, and whenever the window is resized.

NOTE: This widget will only work in standards mode, which requires that the HTML page in which it is run have an explicit <!DOCTYPE> declaration.

Method Detail

get

public static RootLayoutPanel get()

Gets the singleton instance of RootLayoutPanel. This instance will always be attached to the document body via RootPanel.get().

Note that, unlike RootPanel.get(String), this class provides no way to get an instance for any element on the page other than the document body. This is because we know of no way to get resize events for anything but the window.
