parameters using object properties. Object properties can be set
globally (with gObjectSet). Also, with GtkTreeViewColumn, you
can bind a property to a value in a GtkTreeModel. For example, you
can bind the "active" property on the cell renderer to a boolean value
in the model, thus causing the check button to reflect the state of
the model.gtkCellRendererToggleNew()GtkCellRenderer] the new cell renderer
