EnableEventHandler -- enable Hollywood's event handler / OBSOLETE
Attention: This function is no longer supported as of Hollywood 1.9. Please use CheckEvent() instead.

This function enables the internal event handler of Hollywood. This means, that you do not have to call WaitEvent() any longer because Hollywood will always check if there are any events that occurred. Using the internal event handler is useful if you want to call some functions when there is no input but also monitor user input, e.g. if you are doing a slide show with some effects you cannot call WaitEvent() every second but you still want that the user can quit the show by pressing some button on your screen. Then it would be wise to call EnableEventHandler(). Once it is enabled, you can do what you want but all events are still monitored.

Please note: Use this function only when you really need it. It has major disadvantages compared to an input loop together with WaitEvent() because you will never know when an event was raised and from where. If Hollywood's event handler is enabled, events can be raised always. It could even happen, that an event breaks commands that are still busy, e.g. DisplayTransitionFX(). It is not a good idea to use EnableEventHandler() in your projects because you will lose the control of your application. EnableEventHandler() is also very likely to be removed from Hollywood in future versions. So you should stay on the safe side, which means: Use an input loop with WaitEvent().


The above code enables the event handler and then starts a slide show but the user will always be able to press a button although you do not call WaitEvent().
