/**
 * #GtkCellRendererCombo renders text in a cell like #GtkCellRendererText from
 * which it is derived. But while #GtkCellRendererText offers a simple entry to
 * edit the text, #GtkCellRendererCombo offers a #GtkComboBox
 * widget to edit the text. The values to display in the combo box are taken from
 * the tree model specified in the #GtkCellRendererCombo:model property.
 * 
 * The combo cell renderer takes care of adding a text cell renderer to the combo
 * box and sets it to display the column specified by its
 * #GtkCellRendererCombo:text-column property. Further properties of the combo box
 * can be set in a handler for the #GtkCellRenderer::editing-started signal.
 * 
 * The #GtkCellRendererCombo cell renderer was added in GTK+ 2.6.
