LinuxQuestions.org - GTK Notbook Change Pages How to

Hello All,

I am trying to write a function to change tabs on a click of a button. My Code is Below. It errors out saying "Gtk-CRITICAL **: gtk_notebook_set_current_page: assertion `GTK_IS_NOTEBOOK (notebook)' failed" I am showing the widget. I know that is in the gnome help.

Any Ideas?

Code:

void btn_login_clicked_cb (GtkButton *btn_login, GtkNotebook *notebook, gpointer user_data)

{

  GtkWidget *login = GTK_WIDGET(btn_login);

  gtk_button_set_label (login, "Please Wait..."); // THIS WORKS :)



  GtkWidget *nb = GTK_WIDGET(notebook);

  gtk_widget_show_all(nb);

  gtk_notebook_set_current_page (nb, 1); // THIS DOES NOT

}

Thank You
