Indicates whether the event is internal.

• True: The event was triggered by the application and not by end-user action.
  
  For example, when an end-user clicks an entry in the main menu, the application initiates a menu event on the corresponding menu item. The InnerEvent property of this menu event is marked true because it was not triggered directly from the menu item, but internally from the main menu processing.
  
• False: The event was triggered by end-user action.
