13 | // Impl notes: | |
3103e8a9 | 14 | // There is no custom data source because doing so unnecessarily sacrifices |
11e62fe6 | 15 | // some native autocompletion behavior (we would have to make our own - |
8f248607 RN |
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 | |
3103e8a9 | 18 | // only one array or be able to display numbers returned by an NSNumber |
8f248607 RN |
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: | |
11e62fe6 WS |
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 | |
8f248607 RN |
32 | // |
33 | // setIntercellSpacing:/setItemHeight: to autoadjust to number of inserted items? | |
