This can't work.

This looks like a function definition, not like function call

1.)Send your parent notebook object with the signal:

g_signal_connect (button, "clicked", on_button1_clicked, parent_object);

Then use something like this in your callback:

void
on_button1_clicked                     (GtkButton       *button,
                                        gpointer         user_data)
{
    do_something_funny (DO_SOMETHING(user_data), TRUE);
}

2.) An other alternativ:

In the main part do somethin like this:
g_object_set_data (G_OBJECT(button), "parent_object", parent_object);

and in your callback

DoSomething *parent_object = g_object_get_data (G_OBJECT(button),
"parent_object");

I prefer solution 1 but if you need more data for your callback and you
don't want to create an struct method 2 can be very useful
