How to catch events of a class in a class helper?
<p>I want to create a helper for TCustomQuery, TQuery, TTable and so on... With a LastRecordPosition property, which I will get with OnBeforeScroll setting that property from RecNo. </p>

<p>How do I create that trigger in that helper class to catch the event without interfere in an user's OnBeforePost if he/she needs one?</p>

<p>I use FireDAC or ZeosLib for older versions.  </p>
