## ŒEVT Event Target

The niladic system function ŒEVT is valid only when you are running a ŒWE callback function in response to an event. It returns a scalar object reference, which is a reference to the object which generated the event. For example, if a callback is running in response to a `Click` event for a .Net `Button` object, ŒEVT will contain a reference to the `Button`.

If no event target is available, it will return a reference to the Null object.
