| 13 | // Impl notes: |
| 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 |
| 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 | // |
