<GVRWidgetViewDelegate> Protocol

  • The GVRWidgetViewDelegate protocol defines methods to handle interactions and state changes for GVRWidgetView and its subclasses.

  • It includes callbacks for user taps, display mode changes, content loading success, and content loading failures.

  • The widgetViewDidTap: method is called when the user taps the widget, similar to the Cardboard viewer's trigger event.

  • widgetView:didChangeDisplayMode: is triggered when the widget's display mode is altered.

  • The protocol provides methods, widgetView:didLoadContent: and widgetView:didFailToLoadContent:withErrorMessage:, to inform the delegate about the status of content loading.
