# Method GTK2.TreeViewColumn()->add_attribute()

Method add_attribute

  `GTK2.TreeViewColumn add_attribute(GTK2.CellRenderer cell_renderer, string attribute, int column)`

Description

  Adds an attribute mapping to the list. The column is the column of the model to get a value from, and the attribute is the parameter on cell_rendere to be set from the value. So for example if column 2 of the model contains strings, you could have the "text" attribute of a W(CellRendererText) get its values from column 2.
