Trouble with Gtk::Notebook::append_page()

[Matt Bragano <maestro485 comcast net>]

I'm having some trouble getting an appended page to become visible after 
it is added to a notebook.  Basically, I call a function that puts an 
appropriate tab together and then appends the new page.  For debugging 
purposes, I put in some code that "cout's" the number of pages as well 
as the text in the tab label, and both of these are accurate.  However, 
the call to append_page() returns 1.  Is there a way to pinpoint why 
append_page() returns 1 instead of 0?

Thanks,
Matt Bragano
