can you please explain me why this code shows nothing except for the last std::cout line in main()? Checked through similar threads on stackoverflow.com, was not able to connect them to mine, is this pointing legal at all? I try to set a function pointer of a class to another class function:
#include <iostream>
class container;
class one {
public:
one()
{
eventsHandler = NULL;
};
~one() {};
void (container::*eventsHandler)();
};
class container {
public:
container()
{
zone = new one;
zone->eventsHandler = &container::events;
};
~container()
{
delete zone;
};
one *zone;
void events()
{
std::cout << "event handler is on..." << std::endl;
};
};
int main()
{
container *test = new container;
test->zone->eventsHandler;
std::cout << "just checker..." << std::endl;
delete test;
system("pause");
};
You should use operator->* for calling the member function pointer, and assign test as the object which will be called on,
(test->*test->zone->eventsHandler)();
or more clear,
(test->*(test->zone->eventsHandler))();
