Because actually retrieving events is very, very expensive. I already use a timer which limits event loop execution to about 100 times per second but I'd like to make an exception in case there are currently events in the queue, that's why I'm looking for a Cocoa equivalent for GetNumEventsInQueue(). Longer story: Yes, I know, my app isn't doing things the Cocoa way but that's not possible because it's a multi-platform app written in C and I need to make the Cocoa backend fit into this fixed, abstracted multi-platform design. Hence, in my NSApplicationDelegate's "didFinishLaunching" I'm immediately doing a [NSApp stop:nil] and I'm then processing events manually using an old-school model of waitEvent() and handleEvents(). Unfortunately, the OS-independent backend calls handleEvents() really, really often so I need a throttle to avoid killing performance of my app. The timer throttling event loop execution to 100 times per second plus GetNumEventsInQueue() worked like a charm on Carbon. But now I'd need a Cocoa equivalent for GetNumEventsInQueue()... -- Best regards, Andreas Falkenhahn mailto:andr...@falkenhahn.com _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
