I've been trying to 'get round' this..... without much success
internally the NoteBook keeps track of it's pages using both a list of
names and a dictionary of name : page attributes 

so I thought you could mess around with these...  

    notebook._pageAttrs[newname] = notebook._pageAttrs[oldname]
    notebook.tab(oldname)["text"]=newname
    notebook._pageNames[index]=newname
    del notebook._pageAttrs[oldname]

However when you try to raise your newly renamed page it fails :-(
because the callback that lifts the page to the top has the page name 
stuck in it like so:

        if self._withTabs:
            # Create the button for the tab.
            def raiseThisPage(self = self, pageName = pageName):
                self.selectpage(pageName)
            tabOptions['command'] = raiseThisPage


Where pageName is the name given at the time the page was created
(the above code is from the insert method in PmwNotebook)

So you would have to do quite a lot of messing around....
replacing the above callback with your own at least...  This is where I
stopped trying...

So in order to keep it simple I would (in your own code) keep a
dictionary  of old vs new page names or something simple like that.
So you above method would look something like this:-


def _onSelect_(self, pageName):
    realPageName = self.myPageDict[pageName]
    Proxy.DataProxy().containerSelect(realPageName)
    return 



Or failing that convert the pageName into a page index (an integer)
using the notebook.index(pageName) method.

P.S  Most people on this list do not top post.  (I'm not saying this is
good _or_ bad ;-)
