Introduction to Carbon-Cocoa Integration Guide

Explains how to use both Carbon and Cocoa in developing an application.

Who Should Read This Document?

This document assumes you are programming for Cocoa in Objective-C and does not discuss Java integration issues. To get the full benefit of this document, you should have experience programming in either the Cocoa or Carbon environment and you should also have some basic knowledge of the other environment. The See Also section contains a list of documents to help you gain this knowledge.

Organization of This Document

You should be familiar with a few fundamental concepts before you begin to integrate Cocoa and Carbon in the same application. These concepts are covered in the following articles:

Carbon and Cocoa User Interface Communication discusses how Mac OS X communicates user events between Carbon and Cocoa application environments.

Preprocessing Mixed-Language Code lists filename extensions you can use when you mix programming languages in a project.

Interchangeable Data Types provides information on Foundation (Cocoa) and Core Foundation (Carbon) data types you can use interchangeably.

Using Carbon and Cocoa in the Same Application provides a brief overview of how to combine Carbon and Cocoa code in an application. Includes a discussion of C-callable wrapper functions.

The concepts discussed in the preceding articles are put into practice in the sample code provided in these articles:

Using Cocoa Functionality in a Carbon Application describes how to use Cocoa functionality unrelated to the user interface in a Carbon application.
