Can i know when someone clicks on a SOP?

Hello, I`m trying to create a 3d interface that uses geometry SOP’s as buttons, how can I know when someone clicks on one of the geo ops?

If you mean clicking on a rendered geometry, you have to use the Render Pick CHOP or DAT (see the Operator Snippets in the Help menu).
If you mean clicking on a SOP operator in a network view, you can use the rolloverOP member of the UI class.

Exactly what I was looking for, thanks!!!

So, Im working with the Reder Pick DAT and I find that it outputs two lists into the callbacks DAT, events and eventsPrev, ¿is there any difference between the two? I cant seem to find one…
