A widget for displaying a single cell of a GtkTreeModel.
A GtkCellView displays a single row of a
GtkTreeModel, using cell renderers just like
GtkTreeView. GtkCellView doesn't support some
of the more complex features of GtkTreeView,
like cell editing and drag and drop.
The GtkCellView class is used in GtkComboBox which
is therefore capable of displaying several columns of one model at once.
