A combobox permits a single selection only. Combobox items are numbered
from zero.
If you need a customized combobox, have a look at wxComboCtrl,
wxOwnerDrawnComboBox, wxComboPopup and the ready-to-use wxBitmapComboBox.
+ Please refer to wxTextEntry documentation for the description of methods
+ operating with the text entry part of the combobox.
