C + + class function pointers

In the study of quick-3.3, tracing the function of the Touch Event Distribution section found a rare (odd) notation:->*.

void Widget::p ushdownevent () {    this->retain ();    if (_toucheventcallback)    {        _toucheventcallback (this, Toucheventtype::began);    }        if (_toucheventlistener && _toucheventselector)    {        (_toucheventlistener->*_toucheventselector) ( This,touch_event_began);    }    This->release ();}

After investigation this is the legendary class function pointer, you write an example to test.

Fucktest.hclass fucktest{public:void shitFunction1 (void) {printf ("Liujianlog:call  ShitFunction1");} void ShitFunction2 (void);};

#include <stdio.h> #include "FuckTest.h" typedef void (fucktest::* shitfunctionoutside) (void);//define a class member function int Main (int argc, const char * argv[]) {shitfunctionoutside shitfunctionoutside= &FuckTest::shitFunction1; Fucktest fucktest; (fucktest.*shitfunctionoutside) ();//here. *    return 0;}
