13// Impl notes:
14// There is no custom data source because doing so unnecessarily sacrifices
15// some native autocompletion behaviour (we would have to make our own -
16// the SimpleComboBox sample does so in the developer folder that
17// comes with OSX). One reason you might want this would be to have
18// only one array or be able to display numbers returned by an NSNumber
19// from the methods.
20//
21// One problem though is that wxCB_SORT isn't implemented...
22//
23// Also, not sure if it is correctly getting text field events since
24// I'm using SetNSComboBox instead of SetNSTextField
25//
26// doWxEvent is really hackish... but since there's only one event...
27//
28// Ideas for future improvement - other notes:
29// Combox w/o wxCB_DROPDOWN doesn't seem to be implementable
30//wxCB_READONLY 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.
31//wxCB_SORT is possible with data source
32//
33// setIntercellSpacing:/setItemHeight: to autoadjust to number of inserted items?
34//
