Detailed Description

CallBacks object-oriented (object + method).

CallBack is nothing more than a function pointer + optionally an object to call it on. It may be null, in which case doCall() will simply do nothing. If you want to be able to send a CallBack, you must provide a 'sender' CallBacker* (usually 'this').

Constructor & Destructor Documentation

CallBack::CallBack ( CallBacker *  o = 0, CallBackFunction  f = 0  )

CallBack::CallBack ( StaticCallBackFunction  f )

Member Function Documentation

static bool CallBack::addToMainThread ( const CallBack &  , CallBacker *  = 0  )

static

Unconditionally add this to main event loop. For thread safety, the removeFromMainThread() must be called in the destructor.

static bool CallBack::callInMainThread ( const CallBack &  , CallBacker *  = 0  )

static

If in main thread or no event-loop is present, it will be called directly. Otherwise, it will be put on event loop. For thread safety, the removeFromMainThread() must be called in the destructor.

Returns

true if the callback was called directly.
