 * and Layout member, etc.  When a ScreenLoader draws, it shows a {@link
 * com.smartgwt.client.widgets.layout.ScreenLoader#getLoadingMessage loading message} if {@link
 * com.smartgwt.client.widgets.layout.ScreenLoader#getShowLoadingMessage enabled}, performs an RPC to the {@link
 * com.smartgwt.client.rpc.RPCManager#screenLoaderURL screenLoaderURL} to load the screen, if necessary, and finally embeds
 * the {@link com.smartgwt.client.widgets.layout.ScreenLoader#getScreenName screen} within the layout. <P> The last
 * top-level UI component (Canvas subclass) defined by the screen is set as the layout contents. Top-level in this case
 * means that the UI component is not contained in another UI component as a member or child. <p> The ScreenLoader relies
 * on the XMLHttpRequest object which can be disabled by end-users in some supported browsers.  See {@link
