Interface CGEventTapCallBackI

All Superinterfaces:
org.lwjgl.system.CallbackI, org.lwjgl.system.Pointer
All Known Implementing Classes:
CGEventTapCallBack
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface CGEventTapCallBackI extends org.lwjgl.system.CallbackI
Instances of this interface may be passed to the EventTapCreate method.

    • invoke

      long invoke(long proxy, int type, long event, long userInfo)
      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.
