Bob,
Thanks for the info but that only works if your app is not already
loaded. Here is the code I used to catch if the system has been turned off
then back on.
static Boolean PreHandleEvent(EventPtr eventP)
{
static Boolean bPowerOff=false;
Boolean handled;
handled = false;
if (bPowerOff)
{ // we got an event after powering off
// so we have turned back on
// do whatever you need to do here
bPowerOff=false;
}
if (eventP->eType == keyDownEvent)
{
if (eventP->data.keyDown.chr == vchrPowerOff)
{
bPowerOff=true;
// the power has been turned off
}
}
return handled;
}
For this to work you will need to call PreHandleEvent before SysHandleEvent
in your AppEventLoop.
