How can I make click on a widget using an overlap box instead of a button in the controller?

Hi there.

That is the question: How can I make click on a widget using an overlap box instead of a button in the controller?

This is specifically oriented towards the web browser plugin, and I already asked for this in another thread, but I receive no answer, so I though in asking the question in a different and more broad way.

Some help could be really appreciated, I´m trying to mimic a tablet behaviour with the web browser widget, and I can make click in the browser using a button, but I want to do it making an overlap with a detector and an object.

Best regards and thanks!!!

P.S.: again… help please!
