A combobox permits a single selection only. Combobox items are numbered from zero.
+If you need a customized combobox, have a look at \helpref{wxComboCtrl}{wxcomboctrl},
+\helpref{wxOwnerDrawnComboBox}{wxownerdrawncombobox}, \helpref{wxComboPopup}{wxcombopopup}
+and the ready-to-use \helpref{wxBitmapComboBox}{wxbitmapcombobox}.
