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. | |
