14 // There is no custom data source because doing so unnecessarily sacrifices
15 // some native autocompletion behavior (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
21 // One problem though is that wxCB_SORT isn't implemented...
23 // Also, not sure if it is correctly getting text field events since
24 // I'm using SetNSComboBox instead of SetNSTextField
26 // doWxEvent is really hackish... but since there's only one event...
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
33 // setIntercellSpacing:/setItemHeight: to autoadjust to number of inserted items?
36 //example of autocompletion from SimpleComboBox Example
