-/* NOTE: The old method of idle event handling added the handler using the
- [NSRunLoop -performSelector:target:argument:order:modes] which caused
- the invocation to occur at the begining of [NSApplication
- -nextEventMatchingMask:untilDate:expiration:inMode:dequeue:]. However,
- the code would be scheduled for invocation with every iteration of
- the event loop. This new method simply overrides the method. The
- same caveats apply. In particular, by the time the event loop has
- called this method, it usually expects to receive an event. If you
- plan on stopping the event loop, it is wise to send an event through
- the queue to ensure this method will return.
- See wxEventLoop::Exit() for more information.
-
- This overridden method calls the superclass method with an untilDate
- parameter that indicates nil should be returned if there are no pending
- events. That is, nextEventMatchingMask: should not wait for an event.
- If nil is returned then idle event processing occurs until the user
- does not request anymore idle events or until a real event comes through.
-
- RN: Even though Apple documentation states that nil can be passed in place
- of [NSDate distantPast] in the untilDate parameter, this causes Jaguar (10.2)
- to get stuck in some kind of loop deep within nextEventMatchingMask:, thus we
- need to explicitly pass [NSDate distantPast] instead.
