:mod:`MiniAEFrame` --- Open Scripting Architecture server support
=================================================================
.. module:: MiniAEFrame
:platform: Mac
:synopsis: Support to act as an Open Scripting Architecture (OSA) server ("Apple Events").
.. index::
single: Open Scripting Architecture
single: AppleEvents
module: FrameWork
The module :mod:`MiniAEFrame` provides a framework for an application that can
function as an Open Scripting Architecture (OSA) server, i.e. receive and
process AppleEvents. It can be used in conjunction with :mod:`FrameWork` or
standalone. As an example, it is used in :program:`PythonCGISlave`.
The :mod:`MiniAEFrame` module defines the following classes:
.. class:: AEServer()
A class that handles AppleEvent dispatch. Your application should subclass this
class together with either :class:`MiniApplication` or
:class:`FrameWork.Application`. Your :meth:`__init__` method should call the
:meth:`__init__` method for both classes.
.. class:: MiniApplication()
A class that is more or less compatible with :class:`FrameWork.Application` but
with less functionality. Its event loop supports the apple menu, command-dot and
AppleEvents; other events are passed on to the Python interpreter and/or Sioux.
Useful if your application wants to use :class:`AEServer` but does not provide
its own windows, etc.
.. _aeserver-objects:
AEServer Objects
----------------
.. method:: AEServer.installaehandler(classe, type, callback)
Installs an AppleEvent handler. *classe* and *type* are the four-character OSA
Class and Type designators, ``'****'`` wildcards are allowed. When a matching
AppleEvent is received the parameters are decoded and your callback is invoked.
.. method:: AEServer.callback(_object, **kwargs)
Your callback is called with the OSA Direct Object as first positional
parameter. The other parameters are passed as keyword arguments, with the
4-character designator as name. Three extra keyword parameters are passed:
``_class`` and ``_type`` are the Class and Type designators and ``_attributes``
is a dictionary with the AppleEvent attributes.
The return value of your method is packed with :func:`aetools.packevent` and
sent as reply.
Note that there are some serious problems with the current design. AppleEvents
which have non-identifier 4-character designators for arguments are not
implementable, and it is not possible to return an error to the originator. This
will be addressed in a future release.
