The question posed in the first paragraph seems to be basically the same as the question in your [second post](https://discourse.processing.org/t/g4p-defining-handlebuttonevents-in-a-class/18262) which I have answered so I suggest you look there for an answer.

No but you can test the event type inside the event handler e.g.  
`if(event == GEvent.CLICKED) { // do something`
