Re: Array of GtkEntry widgets

[Todd Kulesza <todd dropline net>]

It looks like you need an array of pointers, not just a single pointer. 
 Try:
struct foo
{
        GtkWidget **array_entry;
};

and then:
array_entry = g_new0 (GtkWidget *, number_of_objects);

which can then be accessed as follows:

array_entry [0] = gtk_entry_new ();
array_entry [1] = gtk_entry_new ();

and so on.
