\section{Standard Module \sectcode{MiniAEFrame}}

\label{module-MiniAEFrame}
|
||
|
|
|
||
|
|
The module \var{MiniAEFrame} provides a framework for an application
|
||
|
|
that can function as an OSA server, i.e. receive and process
|
||
|
|
AppleEvents. It can be used in conjunction with \var{FrameWork} or
|
||
|
|
standalone.
|
||
|
|
|
||
|
|
This module is temporary, it will eventually be replaced by a module
|
||
|
|
that handles argument names better and possibly automates making your
|
||
|
|
application scriptable.
|
||
|
|
|
||
|
|
The \var{MiniAEFrame} module defines the following classes:
|
||
|
|
|
||
|
|
\setindexsubitem{(in module MiniAEFrame)}
|
||
|
|
|
||
|
|
\begin{funcdesc}{AEServer}{}
|
||
|
|
A class that handles AppleEvent dispatch. Your application should
|
||
|
|
subclass this class together with either
|
||
|
|
\code{MiniAEFrame.MiniApplication} or
|
||
|
|
\code{FrameWork.Application}. Your \code{__init__} method should call
|
||
|
|
the \code{__init__} method for both classes.
|
||
|
|
\end{funcdesc}
|
||
|
|
|
||
|
|
\begin{funcdesc}{MiniApplication}{}
|
||
|
|
A class that is more or less compatible with
|
||
|
|
\code{FrameWork.Application} but with less functionality. Its
|
||
|
|
eventloop 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 \code{AEServer} but does not
|
||
|
|
provide its own windows, etc.
|
||
|
|
\end{funcdesc}
|
||
|
|
|
||
|
|
\subsection{AEServer Objects}
|
||
|
|
|
||
|
|
\setindexsubitem{(AEServer method)}
|
||
|
|
|
||
|
|
\begin{funcdesc}{installaehandler}{classe\, type\, callback}
|
||
|
|
Installs an AppleEvent handler. \code{Classe} and \code{type} are the
|
||
|
|
four-char OSA Class and Type designators, \code{'****'} wildcards are
|
||
|
|
allowed. When a matching AppleEvent is received the parameters are
|
||
|
|
decoded and your callback is invoked.
|
||
|
|
\end{funcdesc}
|
||
|
|
|
||
|
|
\begin{funcdesc}{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-char designator as name. Three extra keyword parameters are
|
||
|
|
passed: \code{_class} and \code{_type} are the Class and Type
|
||
|
|
designators and \code{_attributes} is a dictionary with the AppleEvent
|
||
|
|
attributes.
|
||
|
|
|
||
|
|
The return value of your method is packed with
|
||
|
|
\code{aetools.packevent} and sent as reply.
|
||
|
|
\end{funcdesc}
|
||
|
|
|
||
|
|
Note that there are some serious problems with the current
|
||
|
|
design. AppleEvents which have non-identifier 4-char 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.
