public long invoke(long proxy, int type, long event, long userInfo) Implements org.lwjgl.system.macosx.CGEventTapCallBackI.invoke. Doc from org.lwjgl.system.macosx.CGEventTapCallBackI.invoke. A client-supplied callback function that’s invoked whenever an associated event tap receives a Quartz event. The callback is passed a proxy for the tap, the event type, the incoming event, and the user-defined data specified when the event tap was created. The function should return the (possibly modified) passed-in event, a newly constructed event, or `NULL` if the event is to be deleted. The event passed to the callback is retained by the calling code, and is released after the callback returns and the data is passed back to the event system. If a different event is returned by the callback function, then that event will be released by the calling code along with the original event, after the event data has been passed back to the event system.
