302 Yet another way of getting messages into Command. This one is for events that
303 are not standard button presses (or UDP generated buttons). It is also not for
304 events that are generated as a result of other events (events that can safely
305 call postMessageNoLock and be guaranteed that the message will be processed
306 because it is known that the queue is currently being processed).
307 This is for events that come from outer space and can occur when the master
308 mutex is locked or not, they need to be queued and executed but it doesn't
310 Actually so far it is for events caused by the video stream - aspect ratio
311 changes. These can occur when the master mutex is locked and so postMessage
312 doesn't work. postMessageNoLock doesn't work because if the mutex *isn't*
313 locked at the time then the message could be sat around a while before
315 The whole message system was at first supposed to prevent the problem of
316 calling a function on an object that had just been deleted, by ordering
317 messages such that all calls are done before object deletion. However,
318 because of the new centralised messaging system and the fact that BoxStack
319 locates the destination object before calling it, the messaging system now
320 allows the kind of sloppy calls it was supposed to stop. Weird huh. This
321 is mentioned here because the video stream might generate an event just as
322 the user hits stop. The mutex is locked, and by the time the message
323 is examined the vvideorec/live has been deleted. This doesn't matter because
324 boxstack will drop the message if it can't find the matching object to
326 Finally, all this is fine and dandy, except that I'm not 100% sure that
327 this sloppy postMessage and hope a queued signal will force it to be processed
328 thingy will actually work. Hmmm.
329 Lastly <g>, I will consider making the naming system a little more sane
