[Tkinter-discuss] String-names and the NoteBook entryfield

[Peter Milliken]

Hi Chris,

Each notebook "page" is created using an instance of tkinter.Frame and
tkinter.Button (according to the reference page for NoteBook).

So your first problem would be that "buttons" can't be typed into - you need
to replace the Button component of each page with an EntryField -> which
changes to an grayed out entryfield (or something similar) once the user has
supplied the name. 

So (re)searching back into the class hierachy reveals that classes derived
from Pmw.MegaArchType's can have the "default" components from which they
are built "overridden" (refer to the "pyclass component option" section of
Pmw.MegaArchType). There are some "clues" here as to what you might have to
do - perhaps examine the code of NoteBook and then create a class that
inherits from NoteBook - which uses an entry widget of some form in the
construction of a new page and then either changes it to "Button" or "greys"
it out so it can't be changed after the user has supplied the name.
Certainly that is how I would proceed - inherit from NoteBook and create a
new class that offers this "feature" - you'll then have a nice re-usable
component that you could share with the rest of us :-) 

At first glance it is a non-trivial exercise i.e. more time than I have left
in my lunch hour to nut this one out :-) So goodluck with your journey.

Peter
