<B>Note</B>: if you have a binary-only release of MacPython you will not

|
|
have this demo installed. Install the developer option (in the standard installer) or
|
|
|
|
|
a source release if you want to embed

Python in other applications. <p>

Embedding Python on the mac is pretty similar to embedding it on other
|
|
|
|
|
platforms, but a few points need mentioning:
|
|
|
|
|
|
|
|
|
|
<UL>
|
|
|
|
|
<LI> You call <CODE>PyMac_Initialize()</CODE> in stead of
|
|
|
|
|
<CODE>Py_Initialize()</CODE>. The prototype is in <CODE>macglue.h</CODE>.
|
|
|
|
|
This call initializes the toolbox, GUSI (if needed), sets up the correct
|
|
|
|
|
resource files and calls Py_Initialize.
|
|
|
|
|
|
|
|
|
|
<LI> You have to be consequent in your use of GUSI. If the library uses
|
|
|
|
|
it so should your program and vice versa.
|
|
|
|
|
|

|
|
|
<LI> The console-behaviour (close-on-exit, etc) is controlled by Python
|
|
|
|
|
but you can overwrite this with <code>PyMac_SetConsoleHandler()</code>.

|
|
|
|
The Python environment is started with a dummy argc and argv, and initial
|
|
|
|
|
startup options are obtained through the usual means, except that the
|
|
|
|
|
user pression the option-key will not result in an interactive dialog.
|
|
|
|
|
You can, however, set startup options on your program in the same way as you
|
|
|
|
|
do for applets, by dragging your application to <code>EditPythonPrefs</code>. <p>
|
|
|

|
|
The most logical way to embed Python is to link it against the shared
|
|
|
|
|
library <code>PythonCore</code>. An example project and source can be
|
1998-02-25 11:40:35 -04:00
|
|
|
found in the <a href="embed">embed</a> folder. <p>

|
|

|
|
|
This example code also shows how to override the console: if you pass the
|
|
|
|
|
<code>-q</code> argument in the argument box output is thrown away. If you
|
|
|
|
|
pass the <code>-d</code> option the output is sent to <code>DebugStr</code>
|
|
|
|
|
(so be sure to use this only when running the example under a debugger).
