    Description copied from interface: EnableCheck
    
    Returns a non-null value if the check failed. Sometimes the return value is used (for example, it is displayed as a tooltip for menu-items); sometimes it is not (for example, toolbar buttons don't do anything with the return value). An advanced use of an EnableCheck is simply to change some property of a menu item (such as the text), as it is called when menu items are displayed.
    
    Specified by:
    
    check in interface EnableCheck
    
    Returns:
    
    an error message if the check failed, or null if the check passed
