{
 *  HIObject
 *  
 *  Discussion:
 *    HIObject is the HIToolbox's base class for various objects. In
 *    Mac OS X 10.2 and later, most common user interface objects
 *    (controls, windows, menus, and toolbars) are derived from
 *    HIObject. Code which is external to HIToolbox can also create its
 *    own subclasses of our objects using the routines contained in
 *    this file. There are also polymorphic functions one can use on
 *    any HIObject for getting the class ID, etc. 
 *    
 *    HIObjects are actually CF types under the hood. This means that
 *    they can be put into CF collections and retain/release can be
 *    called on them. 
 *    
 *    An HIObject is essentially a very basic building-block object
 *    which contains an event target. You can create these objects to
 *    use as your own Carbon Event receptors in your application, or
 *    you can subclass existing Toolbox object to suit your needs.
 *    
 *    
 *    You register your subclasses with HIObjectRegisterSubclass,
 *    passing your class ID, the parent class, and an event handler.
 *    You also pass a list of events the handler is interested in.
 *    
 *    
 *    To create an object of your subclass, you call HIObjectCreate,
 *    passing the class ref you registered, as well as an
 *    initialization event. 
 *    
 *    Construction is two-phase: first the basic construction of the
 *    object is done, then initialization is performed. The toolbox
 *    sends construction events bottom-up, as you would expect in C++
 *    or the like. Here is the list of what goes on to create an
 *    object: 
 *    
 *    1)  The Toolbox creates the base HIObject 
 *    
 *    2)  It then installs the event handler you specified when you
 *    registered your subclass. Your handler must listen for
 *    kEventHIObjectConstruct and kEventHIObjectDestruct events. If it
 *    does not, the class cannot be registered (you will get a
 *    paramErr). 
 *    
 *    3)  Next, the Toolbox _directly_ calls your handler with an
 *    kEventHIObjectConstruct event. When called like this, you are not
 *    really being called in the context of a handler stack, so you
 *    cannot do things like CallNextEventHandler. The userData
 *    parameter is what you specified as the inConstructData parameter
 *    to HIObjectRegisterSubclass. Typically, during construction you
 *    will allocate memory yourself to store your own instance data;
 *    this allocation might be as simple as calling malloc or NewPtr,
 *    or it might involve creating your own C++ object. In the
 *    construct event, the base HIObject of the object being created is
 *    passed as the kEventParamHIObjectInstance parameter. Typically
 *    you would store this HIObjectRef in your own instance data for
 *    later use. When handling this construct event, you should be sure
 *    to use SetEventParameter to set the kEventParamHIObjectInstance
 *    parameter in the construction event with your own instance data.
 *    You must use typeVoidPtr as the type. 
 *    
 *    4)  The Toolbox looks for your instance of typeVoidPtr after you
 *    handle the construct event. It then takes that data and stores it
 *    off with the object and also sets the user data of the event
 *    handler it installed to be this instance data. This means that
 *    following the construct event, all calls to your event handler
 *    will have the instance data you returned to us. 
 *    
 *    5)  Once construction has completed successfully, we will send
 *    your object the initialize event passed into HIObjectCreate. At
 *    this point, all events are now sent to your object using standard
 *    Carbon Events mechanisms (it is only the construct event which is
 *    special). When we send the initialization event to your subclass,
 *    you should pass the event to your superclass before proceeding.
 *    You do this with CallNextEventHandler. Once back from that call,
 *    you should verify that the result is noErr, indicating that the
 *    superclass did in fact initialize properly. If it did not, your
 *    should return the error that CallNextEventHandler returned from
 *    your handler as well. The object will be destroyed by the
 *    Toolbox. Your object should be able to be destroyed in a
 *    partially initialized state such as this. This stage is optional,
 *    i.e. an object does not need to respond to the initialize event
 *    unless it is expecting certain parameters to be passed to it at
 *    creation time. This is where those parameters can be fetched.
 *    
 *    
 *    6)  Once initialization is successful, the HIObjectRef is
 *    returned to the caller of HIObjectCreate. From there, you can
 *    have all sorts of cool fun. 
 *    
 *    When someone has called CFRelease enough such that the refcount
 *    of the object drops to zero, the object is destroyed. The Toolbox
 *    will send a kEventHIObjectDestruct event to your object. DO NOT
 *    CALL CALLNEXTEVENTHANDLER. You will be setting yourself up for
 *    some hurt. Just clean up and return from your handler.

 *    <-> kEventParamHIObjectInstance (in/out, typeHIObjectRef)
 *          On entry, this parameter is typeHIObjectRef, and is the

 *  
 *  Summary:
 *    Your object is being initialized. You should read initialization
 *    data from the event and store it into your instance data.
 *  
 *  Discussion:
 *    Your handler should pass this event on to the superclass first
 *    before handling this event. This is done by calling
 *    CallNextEventHandler with the event. When that function returns,
 *    you should make sure the result is noErr. If not, you should NOT
 *    continue to initialize your object.
 *    
 *    Assuming that CallNextEventHandler returned noErr, you may then
 *    proceed to read initialization data from the event parameters, if
 *    any. For example, you might be create an object that includes a
 *    string as part of its instance data. The caller of HIObjectCreate
 *    would create an EventRef and add a string to the event using a
 *    parameter name and type defined by your object. In your objectΥs
 *    kEventHIObjectInitialize event handler, you would read the string
 *    from the event parameter and store it into your instance
 *    data.
 *    
 *    The parameters of this event, therefore, contain the union of all
 *    parameters needed by all base classes of this object to properly
 *    construct themselves.

 *  kEventClassHIObject / kEventHIObjectCreatedFromArchive
 *  
 *  Summary:
 *    Your object has been recreated from an archive.
 *  
 *  Discussion:
 *    This event is a notification that your object has been decoded
 *    from an archive. This event is also sent by IBCarbonRuntime after
 *    recreating a window, control, or menu from a nib file. The event
 *    is provided so that your object can perform any necessary
 *    post-decoding initialization or setup. 
 *    
 *    At the time this event is sent, the object has been completely
 *    decoded and initialized using data from the archive. However, the
 *    object has not yet been returned to the caller of the decoding
 *    API (either HIArchiveCopyDecodedCFType, CreateWindowFromNib, or
 *    CreateMenuFromNib), and so the caller will not be able to install
 *    an event handler on the object for this event before the event is
 *    sent. Therefore, there are only two ways to handle this event: an
 *    object that is a custom subclass of HIObject or HIView can
 *    install a handler for this event in its kEventHIObjectInitialize
 *    handler, or an object (not necessarily a custom subclass) can
 *    have the class ID of a delegate HIObject specified in its
 *    archived data, and the delegate object can have a handler for
 *    this event. 
 *    
 *    This event is only sent to the object that has been decoded; it
 *    is not propagated past that object. It is sent to all handlers
 *    registered for it.
 *  
 *  Mac OS X threading:
 *    Not thread safe
 *  
 *  Parameters:
 *    
 *    --> kEventParamHIObjectInstance (in, typeHIObjectRef)

 *    This event is typically used by UI editing environments that are

 *    object should respond to this event by first calling
 *    CallNextEventHandler, so that superclasses can add their own
 *    event parameters, and then by adding CFDictionaries containing
 *    information about the init event parameters supported by this
 *    object class. Each dictionary should, at a minimum, contain data
 *    for two keys, kHIObjectInitParamEventName and
 *    kHIObjectInitParamEventType, which are both CFStringRefs. The
 *    contents of each string should be a four-character code,
 *    indicating (respectively) the OSType for the event parameter, and

 *  
 *  Parameters:
 *    
 *    inClassID:
 *      The class ID of your class. It should be unique. We recommend
 *      using Java-style com.company.foo naming conventions to avoid
 *      collisions.
 *    
 *    inBaseClassID:
 *      The class ID of the class you derive from. Passing NULL
 *      indicates you wish to subclass HIObject (the base class)
 *      directly.
 *    
 *    inOptions:
 *      Any special options for your class. Currently you must pass 0
 *      for this parameter.
 *    
 *    inConstructProc:
 *      The construction proc for this subclass. You pass the address
 *      of an event handler into this parameter. This handler is called
 *      directly, rather than through the normal event dispatching
 *      mechanism. This means that the EventHandlerCallRef passed in
 *      will be NULL, and you cannot use it for calls like
 *      CallNextEventHandler. Other than that, you should return a
 *      result as usual. After your object is constructed, this proc
 *      will be installed as the event handler for the remaining events
 *      specified in the inEventList parameter. On Mac OS X 10.4 and
 *      later, you may pass NULL to create an "abstract class" that
 *      cannot be instantiated, but can still be used as a base class
 *      for subclasses; if you pass NULL, HIObjectCreate on the class
 *      ID will return hiObjectClassIsAbstractErr.
 *    
 *    inNumEvents:
 *      The number of events you are installing.
 *    
 *    inEventList:
 *      The events your handler wishes to receive. If you are not
 *      creating an abstract class, then you must handle the
 *      kEventHIObjectConstruct and kEventHIObjectDestruct event. If
 *      these events are not specified, an error is returned. An
 *      abstract class may pass 0 for the inNumEvents parameter and
 *      NULL for the inEventList parameter.
 *    
 *    inConstructData:
 *      Pass any info you want passed into your event handler here. For
 *      a C++ hierarchy based on HIObjects, you might actually pass a
 *      static method to construct your object here, and the base class
 *      event handler to do construction as your event handler.

 *  
 *  Summary:
 *    Given an EventHandlerCallRef for an invocation of an event

 *  
 *  Discussion:
 *    This API is typically used by a delegate handler when handling an
 *    event that does not contain a parameter indicating the object to
 *    which the event is sent. For example, a delegate handler for a
 *    kEventTextDidChange event might want to know the HIViewRef of the
 *    text field object that changed; it can get this object by calling
 *    HIObjectGetEventHandlerObject while the delegate handler is
 *    executing. 
 *    
 *    Note that this API does not return the delegate object; it
 *    returns the object to which the delegate is attached. 
 *    
 *    This API may also be useful whenever you have an event handler
 *    installed on an object's event target and you need to know which
 *    object is currently handling the event, especially if the event
 *    does not have a DirectObject parameter or other identifier. For
 *    example, a kEventScrollableGetInfo handler could use this API to
 *    determine the object to which the GetInfo event was sent, without
