>I used a form builder to "experiment" with a few things. Where can I see the code for the different objects, like the Buttonset, for example. I'd like to trap for changes made and it seems like I need to put it in the 'skip' portion of the buttonset, but how would I do that?

Rebuild your project.
After rebuilding you seen new classes in the classes tab.
In the wizbtns class are the buttons.
