If you want to retrieve the value of a parameter
associated with a Carbon event, you need to call
in Chapter 6).
However, while calling the function is fairly straightforward, the
tricky part is figuring out the parameter names and types associated
with the event; you can’t retrieve the proper parameter unless
you know how to specify it properly in your function call. This
appendix provides a solution by listing the parameter names and
types for most common events and for many of the uncommon ones as
well. The parameter names and types are grouped by event class (command,
menu, window, and so on) and then by event kind within each class (mouse
up, mouse down, window closed, and so on).
The Apple Event Manager sends Apple events between applications on the same computer or between applications on remote computers. Applications typically use Apple events to request services and information from other applications or to provide services and information in response to such requests.
If you’re curious, an Apple event conforms to the Apple Event Interprocess Messaging Protocol (AEIMP).
