How to set gtk2 combo box entry place

ruby-talk
1

OK,
i am using ruby-gnome2 to develop a gui app.
I have a combobox that i create with Gtk.ComboBox.new
this is so i can populate it with append_text() and prepend_text()

my question is, i need to be able to set it to a certain value.
like if I have a list of items that i have used to append text to this combo,
apple, 0
orange, 1
pear, 2
grapes, 3

and another function selects say grapes, how do i set the combobox to
show that selection automatically ?

does this make sense?

thanks for any help,
sk

2

widget.set_active(3)

or

widget.active=3

(assuming 3 == grapes ...)
