hello,

i am trying to create a combo box where drop-down bit is a list-store  
with two columns. the following code does not work:

@title = Gtk::ComboBox.new(false)  
renderer = Gtk::CellRendererText.new()  
@title.append\_column(Gtk::TreeViewColumn.new(‘id’, renderer, :text =\>  
0))  
@title.append\_column(Gtk::TreeViewColumn.new(‘name’, renderer, :text =\>  
1))

(the append\_column method does not exist).

i have searched the documentation but still cannot figure this one out  
(it works with tree views).

did i miss some part of documentation?

vlad

See sample code in combo.rb in ruby gnome  
distribution directory  
…/ruby-gnome…/gtk/sample/misc

The following is a simple example.

require “gtk2”

window = Gtk::Window.new(“Gtk::ComboBox Title”)  
window.signal\_connect(“destroy”){Gtk.main\_quit}

model = Gtk::ListStore.new(String,String)  
[[“ID1:”,“J. J. Calhoun”],[“ID2:”,“Hans C. Nirbert”]].each {|id,name|  
iter = model.append  
iter[0] = id  
iter[1] = name  
}  
title = Gtk::ComboBox.new(model)  
renderer = Gtk::CellRendererText.new  
title.pack\_start(renderer,false)  
title.set\_attributes(renderer, :text =\> 0)  
renderer = Gtk::CellRendererText.new  
title.pack\_start(renderer,false)  
title.set\_attributes(renderer, :text =\> 1)

vbox = Gtk::VBox.new  
vbox.add(title)  
window.add(vbox).show\_all  
Gtk.main

good luck
