Forum: wxRuby Notebook Change Page Event Handling

I'm still a bit new to Ruby, but have been using WxRuby for a couple of
months now.  I've created a notebook with a few pages, and am having a
tough time understanding how to implement an event handler that would
get called whenever the page gets changed.

Would someone be kind enough to post a simple example?

Welcome to wxRuby. There are two events : evt_notebook_changing and
evt_notebook_changed. They receive a Wx::NotebookEvent, and the former
can be veto-ed if you want to prevent the change.

There's an example within the bigdemo sample:

Thanks Alex.  That's exactly what I was looking for.
