I don't know.
Okay, so all applications receive low level Carbon events?
Strictly speaking, all applications _create_ low-level Carbon events;
the event structure that's passed from the WindowServer to the app is
not a Carbon event, but a rather is a different event structure that
is private to the WindowServer and Apple frameworks.
These would be of the kEventRawKey... type, correct?
All apps begin by creating events of this type from keyboard events
provided by the WindowServer, yes.
And then does the standard window handler or whatever convert
those raw key events into higher level events for the application
to handle?
For keyboard events, the standard window handler doesn't actually
play a role; keyboard events are handled by a default event handler
installed at the application level for Carbon events, and somewhat
different for Cocoa apps.
For mouse events, the standard window handler does convert these into
higher-level semantic events.
Is an event posted to the application's main event queue
indistinguishable from an event sent to the application by the
Window Server, and will that work for Cocoa applications? If so,
then the mach_inject method is still a possibility.
It would be distinguishable, but I doubt most apps would care.
If you need to insert keyboard events and mouse events into
another application, most likely the best way to do this will be
to use the APIs in CoreGraphics/CGRemoteOperation.h, which are
designed for this purpose.
My concern with doing it that way is that I only want the
application I specifically target to receive these events.
For keyboard events, you can use AXUIElementPostKeyboardEvent to post
an event to a specific application.
On Tiger, you can use CGEventPostToPSN to post events of any time to
a specific process.
