# Class MultiWindow

java.lang.Object
com.smartgwt.client.browser.window.MultiWindow

public class MultiWindow extends Object
Note: this is currently an experimental feature and not covered by normal support guarantees. See `Experimental Features` for more information.
Provides tracking of other Smart GWT browser windows opened by the original window, as `RemoteWindows`.

Includes APIs for:

- Registering event listeners for events on other windows
- Opening a new window and finding a window by name
- Moving, activating, or deactiving a window by name
- Sharing DataSources and their caches between Smart GWT windows
- Sharing `Messaging` channels between Smart GWT windows

Within the OpenFin environment, the underlying implementation is actually via the OpenFin class.

Reloading of child windows is in general supported (but see `autoCopyDataSources`), while reloading the `main window` currently is not.
