public interface OpenFolderCallback extends BrowserAsyncCallback<OpenFolderCallback.Params,OpenFolderCallback.Action>
This callback is invoked when the browser requests to display a file chooser dialog to open a folder. You can use this callback to display the folder chooser dialog, or provide the chosen files without displaying any dialogs.

Use the OpenFolderCallback.Action.open(Path) (File)} method to provide the selected folder to the browser.

Use the OpenFolderCallback.Action.cancel() method to cancel the dialog.

If the callback throws an exception, the OpenFolderCallback.Action.cancel() method will be invoked.
