NOTEBOOK

[Przemysław Lichoń <P Lichon wasko pl>]

How can I get one of NOTEBOOK pages nonactive? (while clicking - smth.
like nonsensitive widget)

I've tried: 
gtk_widget_set_sensitive(gtk_notebook_get_nth_page(GTK_NOTEBOOK(notatnik_glowny),page_number),FALSE);

but this instruction only sets field of NOTEBOOK to nonactive state, so
there's still a possibility
to switch to that page - (that's still active so one can open it).
