#add_row(hash = {}) ⇒ Object

This will add a row to the data model, and fill-in the values from a Hash. This example would add a row to the model and set the name and email fields:

@view.add_row(:name => “Chester”, :email => “chester@chester.com”)

  hash.each_pair { |key, val| row[key] = val }
  return row
end

#select_row(row_number = 0) ⇒ Object

This method will select a given row number. The row will be hilighted, and the GtkSelection object will point to that row. It uses the GtkTreeView#set_cursor method to move the cursor to the specified row.
