Accessing and customizing Events say drag drop

I am Currently trying to customize the bpmn properties panel ,How do I access each event.Say an element is dropped and for which I need to do an action say a popup.

briefly,Should I know the pattern or the complete flow to have control on the events.Or Where should I be looking precisely?

Thanx a lot in advance.I appreciate this whole thing.

could you please elaborate on which libraries you’re using? Which kind of events are you interested in?

To hook up to the event chain you just need to do something like:

eventBus.on('shape.create', function() {
 // logic
