| Graphics.UI.Gtk.TreeList.CellRenderer |
A CellRenderer is an object that determines how the cell of a TreeView widget is displayed.
- Each TreeViewColumn has exactly one accociated CellRenderer. The data supply for a cell is contained in a TreeStore or a ListStore (both subclasses of TreeModel). Each CellRenderer may have several attributes. Each Attribute is associated with one column of the TreeModel database. Thus several columns of a TreeModel may be the supply for one TreeViewColumn.

Set a property statically.
- Instead of using a TreeStore or ListStore to set properties of a CellRenderer this method allows to set such a property for the whole column.
Get a static property.
- See cellRendererSet. Note that calling this function on a property of a CellRenderer object which retrieves its values from a ListStore or TreeStore will result in an abitrary value.
