TreeViewColumn.cellSetCellData

void cellSetCellData(gtk.tree_model.TreeModel treeModel,  gtk.tree_iter.TreeIter iter,  bool  isExpander,  bool  isExpanded)

Sets the cell renderer based on the tree_model and iter. That is, for every attribute mapping in tree_column, it will get a value from the set column on the iter, and use that value to set the attribute on the cell renderer. This is used primarily by the #GtkTreeView.

Parameters

`treeModel`	The #GtkTreeModel to to get the cell renderers attributes from.
`iter`	The #GtkTreeIter to to get the cell renderer’s attributes from.
`isExpander`	true, if the row has children
`isExpanded`	true, if the row has visible children
