Instance Method Details

#add_row(parent, hash = {}) ⇒ Object

def initialize(cols)

super()
args = *flatten_hash(cols).values

alert args.to_s

     self.model = Gtk::TreeStore.new(*args)  # *flatten_hash(cols).values)
     load_columns(cols)
   end

Adds row to the model.  This will return a "row" type iter that responds
to column IDs (symbols).  You need to provide a parent row (iter).
See GtkTreeView#append for more.

The iter is a GtkTreeIter object for the parent or nil for the root of the tree.  The hash argument is a Hash of values to add:

@view.add_row(iter, :name => "Chester", :email => "chester@chesterizer.com")
