What is 'HIObject' ? C++ class?

C++ (more likely) or just C (OO?) ? But.. from wikipedia:

Quote:

HIObject � a completely new object-oriented API which brings to Carbon an OO model for building GUIs. This is available in Mac OS X v10.2 or later, and gives Carbon programmers some of the tools that Cocoa developers have long been familiar with. Starting with Mac OS X v10.2, HIObject is the base class for all GUI elements in Carbon. HIView is supported by Interface Builder, part of Apple's developer tools. Traditionally GUI architectures of this sort have been left to third-party application frameworks to provide. Starting with Mac OS X v10.4, HIObjects are NSObjects and inherit the ability to be serialized into data streams for transport or saving to disk.
HITheme � uses QuickDraw and Quartz to render graphical user interface (GUI) elements to the screen. HITheme was introduced in Mac OS X v10.3, and Appearance Manager is a compatibility layer on top of HITheme since that version.
HIView Manager � manages creation, drawing, hit-testing, and manipulation of controls. Since Mac OS X v10.2, all controls are HIViews. In Mac OS X v10.4, the Control Manager was renamed HIView Manager.
Window Manager � manages creation, positioning, updating, and manipulation of windows. Since Mac OS X v10.2, windows have a root HIView.
Menu Manager � manages creation, selection, and manipulation of menus. Since Mac OS X v10.2, menus are HIObjects. Since Mac OS X v10.3, menu content may be drawn using HIViews, and all standard menus use HIViews to draw.

My strong suspicion is that HiObject and HIToolbox etc is a bridge for Cocoa to communicate with old but still in use Carbon (edit: or whatever is below Cocoa) functions.
