A start at writing a SimpleTree class that holds both a TreeStore and  
a TreeView and simplifies a lot of common cases. Also provides direct  
access to the store and the view if you want to do something more  
complicated. Still needs a lot of work, but I thought I’d get some  
reactions and suggestions before anything got too set in stone. Right  
now there’s barely enough of it to run the example from  
[http://ruby-gnome2.sourceforge.jp/hiki.cgi?tut-treeview-renderer-example](http://ruby-gnome2.sourceforge.jp/hiki.cgi?tut-treeview-renderer-example).  
Code attached, but here’s the interesting part:

# define the tree

s = Gtk::SimpleTree.new([String, String, Integer],  
[“First Name”, 0],  
[“Last Name”, 1,  
{:weight =\> Pango::FontDescription::WEIGHT\_BOLD}],  
[“Age”, format\_age, {:foreground =\> “red”}],  
[“Age”, simple\_age])

# define the initial data

treedata = [  
[‘Maria’, ‘Incognito’],  
[‘Jane’, ‘Average’, 1962,  
[‘Janinita’, ‘Average’, 1985]]]

s.import\_tree(treedata)  
s.sel\_mode = :none  
window.add(s.view)

window.show\_all  
Gtk.main

(the additional column with the ‘simple\_age’ proc is to demonstrate a  
simplified one-argument callback)

Can’t say anything about the implementation or design at the moment,  
but I really like the idea. Be great if there was support for sorting  
and filtering.

Definitely on the to-do list, particularly filtering.
