- installaehandler (classe, type, callback)
-
Installs an AppleEvent handler. Classe and type are the
four-char OSA Class and Type designators, '****' wildcards are
allowed. When a matching AppleEvent is received the parameters are
decoded and your callback is invoked.
- 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: _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
aetools.packevent and sent as reply.
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.
