Thanks: Not sure how you got your example working  
though. Maybe you can give a piece of your code? 🙂

For me, I tried a bit more, and when i used this signal  
instead:

button\_release\_event

and

puts widget.selection.selected[0]

all seems to be fine now.

One problem less on my list, getting  
closer to finish that little MidnightCommander  
clone. 😉

i changed your code a bit.  
this can do multiple selection, which you’ll need in a  
gtk-mini-midnight-commander 🙂

#!/usr/bin/ruby  
require ‘gtk2’  
Gtk.init

# SimpleTreeView.new

class SimpleTreeView

# === initialize

def initialize  
@main\_window = Gtk::Window.new  
@main\_window.set\_size\_request 555,255  
create\_parts  
end

def create\_parts  
@renderer=Gtk::CellRendererText.new  
@renderer.set\_property( ‘background’, ‘lavender’ )  
@renderer.set\_property( ‘foreground’, ‘black’ )

```
@list_store = Gtk::ListStore.new(String)
@tree_view = Gtk::TreeView.new(@list_store)
@tree_view_column = Gtk::TreeViewColumn.new('Laaa',
  @renderer, {:text => 0})
@tree_view.append_column(@tree_view_column)

# Example Data:
iter = @list_store.append
iter.set_value(0, 'aaa')
iter = @list_store.append
iter.set_value(0, 'bbb')
iter = @list_store.append
iter.set_value(0, 'ccc')

```

# @tree\_view.signal\_connect(‘button\_press\_event’) do |widget,event|

# puts "Selection was: "+widget.selection.selected[0]

# end

```
    @tree_view.selection.set_mode(Gtk::SelectionMode::MULTIPLE)
    @tree_view.selection.signal_connect("changed"){|me|
      print me.count_selected_rows," : "
      me.selected_each {|model, path, iter|
            print iter[0]," "
      }
      print "\n"
    }

@main_window.add(@tree_view)
@main_window.show_all
Gtk.main

```

end  
end  
SimpleTreeView.new
