The modules in this chapter are available on the Apple Macintosh only.
|
||||
|
||||
Aside from the modules described here there are also interfaces to
|
||||
various MacOS toolboxes, which are currently not extensively
|
||||
described. The toolboxes for which modules exist are:
|
||||
\code{AE} (Apple Events),
|
||||
\code{Cm} (Component Manager),
|
||||
\code{Ctl} (Control Manager),
|
||||
\code{Dlg} (Dialog Manager),
|
||||
\code{Evt} (Event Manager),
|
||||
\code{Fm} (Font Manager),

||||
\code{List} (List Manager),

\code{Menu} (Moenu Manager),

|
||||
\code{Qt} (QuickTime),
|
||||
\code{Res} (Resource Manager and Handles),
|
||||
\code{Scrap} (Scrap Manager),
|
||||
\code{Snd} (Sound Manager),
|
||||
\code{TE} (TextEdit),
|
||||
\code{Waste} (non-Apple TextEdit replacement) and
|
||||
\code{Win} (Window Manager).
|
||||
|
||||
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 have a \code{__doc__}
|
||||
string describing their arguments and return values, and for
|
||||
additional description you are referred to Inside Mac or similar
|
||||
works.
