- * tkMacOSXCarbonEvents.c --
- *
- * This file implements functions that register for and handle
- * various Carbon Events and Timers. Most carbon events of interest
- * to TkAqua are processed in a handler registered on the dispatcher
- * event target so that we get first crack at them before HIToolbox
- * dispatchers/processes them further.
- * As some events are sent directly to the focus or app event target
- * and not dispatched normally, we also register a handler on the
- * application event target.
