/**
 * A GtkComboBox is a widget that allows the user to choose from a list of
 * valid choices. The GtkComboBox displays the selected choice. When
 * activated, the GtkComboBox displays a popup which allows the user to
 * make a new choice. The style in which the selected value is displayed,
 * and the style of the popup is determined by the current theme. It may
 * be similar to a Windows-style combo box.
 * 
 * The GtkComboBox uses the model-view pattern; the list of valid choices
 * is specified in the form of a tree model, and the display of the choices
 * can be adapted to the data in the model by using cell renderers, as you
 * would in a tree view. This is possible since GtkComboBox implements the
 * #GtkCellLayout interface. The tree model holding the valid choices is
 * not restricted to a flat list, it can be a real tree, and the popup will
 * reflect the tree structure.
 * 
 * To allow the user to enter values not in the model, the “has-entry”
 * property allows the GtkComboBox to contain a #GtkEntry. This entry
 * can be accessed by calling gtk_bin_get_child() on the combo box.
 * 
 * For a simple list of textual choices, the model-view API of GtkComboBox
 * can be a bit overwhelming. In this case, #GtkComboBoxText offers a
 * simple alternative. Both GtkComboBox and #GtkComboBoxText can contain
 * an entry.
 * 
 * # CSS nodes
 * 
 * |[<!-- language="plain" -->
 * combobox
 * ├── button.combo
 * │    ╰── arrow
 * ╰── window.popup
 * ]|
 * 
 * GtkComboBox has a single CSS node with name combobox. It adds the
 * .combo style class to the button that it contains.
 * The button also contains another node with name arrow.
