Mac Forum / Programming / Mac Programming / June 2005Not Receiving quit AppleEvent under Tiger in PP
I have a PP project that is working fine under Panther, but under Tiger it is not receiving the quit AppleEvent when the application is shut down. The application does quit, but none of my destructors are called and LApplication::DoQuit() is definitely not being called. It is almost like I had issued a kill from the command line Is there anyway to trace what is happening here? The application is built with PowerPlant as shipped with CW 8.3 Bryan Hi Bryan, i work with CW 8.3 to, but it works fine (most of the time). Is it a Mach-0 Target, do you use Carbon-Events?

I just did a test and found I can write an AppleScript to Quit the application OK. It just doesnt get the AppleEvent that should be generated by the Quit menu item. > It is a Mach-0 target using WNE.

Is it possible that you are getting the kHICommandQuit Carbon Event? (Just because you're using WNE doesn't mean that you don't have any Carbon Event handlers.) > > It is a Mach-0 target using WNE.

I dont think thats the case unless a default handler is being inserted somehow. As I said, if I send a 'quit' from AppleScript and as I have just found, use the Quit selection from the Dock popup menu, then the apple event is sent and handled correctly.

I setup a Carbon event handler (although this a WNE application) and it seems to do the trick static OSStatus quit_handler(EventHandlerCallRef inHandlerCallRef, EventRef inEvent, void *inUserData) { CAppearanceApp *app = (CAppearanceApp *)inUserData; app->DoQuit(); return(0); } voidCAppearanceApp::SetupQuitHandler(void) { EventHandlerUPP handler; EventTypeSpec eventList = { kEventClassApplication, kEventAppQuit }; handler = NewEventHandlerUPP(quit_handler); InstallEventHandler( ::GetApplicationEventTarget(), handler, 1, &eventList, this, NULL); } > Problem solved - thanks for the pointers guys. For the record, what exactly was the circumstance in which you did not get the quit AppleEvent? In one message you said "shut down", leading me to think you were talking about the computer shutting down, and in another message you mentioned the Quit menu item. > > Problem solved - thanks for the pointers guys. > > For the record, what exactly was the circumstance in which you did not > get the quit AppleEvent?

Oh - sorry about the ambiguity. The problem was occurring when selecting the Quit menu item from the application menu. |
