Member Function Documentation

void CP_EventHandler_Imp::Add (  UInt32  inEventClass,
UInt32  inEventKind,
CP_EventSignal *  inEventSignal,
OSWindow  inWindow = NULL
) 
 

Adds the passed in event and event signal handler to the list of events we maintain. This will also register with the Carbon Event handler the fact that we handle the passed in event class and event kind.

Parameters:
inEventClass The class of the event being handled
inEventKind The kind of the event being handled
inEventSignal The signal to be called when this event class and kind is encountered. Note: This signal will be deleted when the event is removed from the list of events, and should be unique for each event, ie don't assign the same signal to the same event.
inWindow Not used
Exceptions:
CP_OSErrorException Exception thrown in there was a problem adding the event to the Carbon Event handler.
Returns:
void

void CP_EventHandler_Imp::Remove (  UInt32  inEventClass,
UInt32  inEventKind
) 
 

Removes the event hanndler associated with the passed in event class and event kind.

Parameters:
inEventClass The class of the event being handled
inEventKind The kind of the event being handled
Exceptions:
CP_OSErrorException Exception thrown in there was a problem removing the event from the Carbon Event handler.
Returns:
void

bool CP_EventHandler_Imp::HasHandler (  UInt32  inEventClass,
UInt32  inEventKind
) 
 

Returns true if we have an installed handler for the passed in inEventClass and inEventKind.

Parameters:
inEventClass The class of the event being handled
inEventKind The kind of the event being handled
Exceptions:
none 
Returns:
bool True if the event class / kind handler exists.

CP_EventSignal * CP_EventHandler_Imp::FindHandler (  UInt32  inEventClass,
UInt32  inEventKind
) 
 

Returns the CP_EventSignal that will handle the passed in Carbon Event, based on the event class and event kind.

Parameters:
inEventClass The class of the event being handled
inEventKind The kind of the event being handled
Exceptions:
none 
Returns:
CP_EventSignal * The CP_EventSignal for the event.

EventRef  inEvent,
void *  inUserData
)  throw () [static, private]
 

Callback for the Carbon Event handler when it has a registered event to process. This will look up the CP_EventSignal and call it to handle the event.

Parameters:
inHandlerCallRef Carbon Event handler call ref for the event.
inEvent Carbon Event event ref for the event.
inUserData User supplied data passed to this callback, in this case it points to the instance of this class that will handle the event.
Exceptions:
none 
Returns:
