Re: Possible to disable find?

[Silvia Brunet]

You can try a prehandler event function

#define FindButton 266

static void EventLoop(void)
{
static EventType event;
Word error;


do
{
// Get the next available event.
EvtGetEvent(&event, /*5*/ evtWaitForever);
if(!PreHandler(&event))
// Give the system a chance to handle the event.
if( !SysHandleEvent (&event))
if( !MenuHandleEvent (CurrentMenu, &event, &error))
// Give the application a chance to handle the event.
if( !ApplicationHandleEvent(&event) )
// Let the form object provide default handling of the event.
FrmDispatchEvent(&event);
}
while (event.eType != appStopEvent);
}

static Boolean PreHandler(EventPtr event)
{
if((event->eType == keyDownEvent)&&(event->data.keyDown.modifiers & commandKeyMask))
{
if (event->data.keyDown.chr == FindButton)
return(true);
else
return(false);
}

return (false);
}

This will prevent the system to handle the event when the find is pressed.

This is the easiest way to get arround it, if you want the values for the other
buttons like the cradle etc, you could manage them all like that, i have the
codes just let me know
