- Same as wxCB_DROPDOWN but only the strings specified as the combobox
- choices can be selected, it is impossible to select (even from a
- program) a string which is not in the choices list.
+ A combobox with this style behaves like a wxChoice (and may look in

@style{wxCB_SORT}
Sorts the entries in the list alphabetically.
