I would like to determine if my application was started by the
opening of a specific file type.
I have to do this before the main event loop starts so I am trying to
peek for the presence of a "open documents" apple event. I use the
function FindSpecificEventInQueue to match for a carbon event of
class kEventClassAppleEvent and of type kEventAppleEvent and I check
that the kEventParamAEEventClass and kEventParamAEEventID parameters
are kCoreEventClass and kAEOpenDocuments respectively.
But this is where I am stuck...
I don't know how to get the AppleEvent structure in order to traverse
the descriptor tree to determine what files are to be opened.
It seems that the only way to get the AppleEvent from the carbon
event is to actually dispatch it using AEProcessAppleEvent. I tried
calling AEProcessAppleEvent with the event that I search for in the
event queue (without removing it) but I get an noOutstandingHLE error.
Does anyone have any other ideas of how to do this?
Is there any other way to determine what files were opened at startup
other than by apple events?
BTW,
I found that I have to kick the event loop to get the initial apple
events to appear. Without doing this I don't find any apple events in
the queue. Receive the next event without waiting nor removing it:
ReceiveNextEvent(0, NULL, 0.0, false, NULL);
Don't ask how I figured this out. I don't know if this is reliable.
Does anybody know a better (proper) way of getting the apple events
to appear?
Thanks in advance,
Mark
