37.8. Mac OS Toolbox Modules¶
These are a set of modules that provide interfaces to various legacy Mac OS toolboxes.
If applicable the module will define a number of Python objects for the various
structures declared by the toolbox, and operations will be implemented as
methods of the object. Other operations will be implemented as functions in the
module. Not all operations possible in C will also be possible in Python
(callbacks are often a problem), and parameters will occasionally be different
in Python (input and output buffers, especially). All methods and functions
__doc__ string describing their arguments and return values, and
for additional description you are referred to Inside Macintosh or similar works.
These modules all live in a package called
Carbon. Despite that name they
are not all part of the Carbon framework: CF is really in the CoreFoundation
framework and Qt is in the QuickTime framework. The normal use pattern is
from Carbon import AE
Most of the OS X APIs that these modules use are deprecated or removed in recent versions of OS X. Many are not available when Python is executing in 64-bit mode. The Carbon modules have been removed in Python 3. You should avoid using them in Python 2.
CFURL objects are supported, some only partially.
Carbon.Icn — Carbon Icon Manager¶
Carbon.Scrap — Scrap Manager¶
This module is only fully available on Mac OS 9 and earlier under classic PPC MacPython. Very limited functionality is available under Carbon MacPython.
The Scrap Manager supports the simplest form of cut & paste operations on the Macintosh. It can be use for both inter- and intra-application clipboard operations.
Scrap module provides low-level access to the functions of the Scrap
Manager. It contains the following functions:
Return current information about the scrap. The information is encoded as a tuple containing the fields
(size, handle, count, state, path).
Field Meaning size Size of the scrap in bytes. handle Resource object representing the scrap. count Serial number of the scrap contents. state Integer; positive if in memory,
0if on disk, negative if uninitialized.
path Filename of the scrap when stored on disk.

- Apple’s documentation for the Scrap Manager gives a lot of useful information about using the Scrap Manager in applications.
