File: ExamplePrefs.c
Abstract: Demo program showing how the custom Icon List Definition function might
be used in creating a Preferences window/dialog.
Version: 2.0
Change History:
<2.0> Carbonized
added RunningInMacOSX to support the Aqua appearance
<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)
