Glade stores pointers to all the widgets and provides a lookup_widget()
function so you can get these pointers.
The FAQ (available at http://glade.gnome.org) describes this a bit:
4.5 How do I get a pointer to a widget from within a signal handler?
If you have a pointer to any widget in a window, you can get a pointer to
any other widget in the window using the lookup_widget() function that Glade
provides (in support.c).
You pass it a pointer to any widget in a window, and the name of the widget
that you want to get. Usually in signal handlers you can use the first argument
to the signal handler as the first parameter to lookup_widget(), e.g.
void
on_button1_clicked (GtkButton *button,
gpointer user_data)
{
GtkWidget *entry1;
entry1 = lookup_widget (GTK_WIDGET (button), "entry1");
...
}
