File: ExamplePrefs.c |
Abstract: Demo program showing how the custom Icon List Definition function might |
be used in creating a Preferences window/dialog. |
Version: 1.0 |
Change History: |
<1.0> first release version, this is totally Mac OS 8.6-savvy |
it's kind of cheating but we decided to use Carbon Event |
HI Command IDs even though we're not using Carbon Events |
(or Carbon for that matter) |
