60/* NOTE: The old method of idle event handling added the handler using the
61 [NSRunLoop -performSelector:target:argument:order:modes] which caused
62 the invocation to occur at the begining of [NSApplication
63 -nextEventMatchingMask:untilDate:expiration:inMode:dequeue:]. However,
64 the code would be scheduled for invocation with every iteration of
65 the event loop. This new method simply overrides the method. The
66 same caveats apply. In particular, by the time the event loop has
67 called this method, it usually expects to receive an event. If you
68 plan on stopping the event loop, it is wise to send an event through
69 the queue to ensure this method will return.
70 See wxEventLoop::Exit() for more information.
