Description Tomasz Ostrowski 2007-05-30 09:47:55 UTC 
Methods
 int Gtk::Notebook::get_n_pages()
 int Gtk::Notebook::page_num(const Widget& child)
should be declared "const", as they do not change object state.

Other information:
This causes the following compilation error when this methods are used on a
const declared notebook:
    error: passing ‘const Gtk::Notebook’ as ‘this’ argument of
    ‘int Gtk::Notebook::get_n_pages()’ discards qualifiers
Comment 1 Murray Cumming 2007-06-02 21:31:07 UTC 
OK. We should add const versions of these functions and deprecate the non-const ones. A patch would be welcome.

As a workaround for now, a const_cast<> can be used.

Done in svn trunk for gtkmm 2.11/12
