I'm presently working on a project in Dashcode, and am getting increasingly frustrated at how the default classes have very little in the way of bind-able events much like jQuery uses. Dashcode doesn't let me edit the files, which I'm guessing is because until the project is exported they're a standard set of core classes. I'm thus contemplating extending the classes, but am unsure how Dashcode relates a component to a class.
Any ideas how best to accomplish something like this?
