Thank you so much, Murray. In ruby works fine also.
renderer = Gtk::CellRendererText.new
column = Gtk::TreeViewColumn.new("Prize", renderer,'text' =>
PRIZE_COLUMN)
column.set_cell_data_func(renderer) {|column, cell, model, iter|
cell.text=sprintf("%.2f",iter[PRIZE_COLUMN])
}
Ruby-gnome Rocks!!!!!!!!!!!!!!!!!
Regards.
