62/* NOTE: The old method of idle event handling added the handler using the
63 [NSRunLoop -performSelector:target:argument:order:modes] which caused
64 the invocation to occur at the begining of [NSApplication
65 -nextEventMatchingMask:untilDate:expiration:inMode:dequeue:]. However,
66 the code would be scheduled for invocation with every iteration of
67 the event loop. This new method simply overrides the method. The
68 same caveats apply. In particular, by the time the event loop has
69 called this method, it usually expects to receive an event. If you
70 plan on stopping the event loop, it is wise to send an event through
71 the queue to ensure this method will return.
72 See wxEventLoop::Exit() for more information.
422d306c 73
eba2de69
DE
74 This overridden method calls the superclass method with an untilDate
75 parameter that indicates nil should be returned if there are no pending
76 events. That is, nextEventMatchingMask: should not wait for an event.
77 If nil is returned then idle event processing occurs until the user
78 does not request anymore idle events or until a real event comes through.

f6d0a117
RN
80 RN: Even though Apple documentation states that nil can be passed in place
81 of [NSDate distantPast] in the untilDate parameter, this causes Jaguar (10.2)
82 to get stuck in some kind of loop deep within nextEventMatchingMask:, thus we
83 need to explicitly pass [NSDate distantPast] instead.
