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