Re: Trying to add a page to a notebook

[Tristan Van Berkom <tvb gnome org>]

a.) you dont show the widgets you add in generateButtons
b.) you dont remove the original page either

maybe it works and adds an invisible page every time ?

And... maybe it will be easier if you hold on to a GtkBox
child of the first page and reconstruct the contents of
that instead (so as to be sure not to muck up page indexes).

Cheers,
        -Tristan
