C++ :: Class Calendar - Pointer To A Function Error

I have a class Calendar which has an attribute of priority queue, that accepts records of structure defined as:

typedef void (Calendar::*eventPointer)();
struct activationRecord {
double Time;
int Priority;
eventPointer activationEvent;
};

And here is the problem. Whole day I've been trying to fill the Calendar with some test entries by calling the method

void Calendar::calendarPush(double Time, int Priority, eventPointer event)

This is how I call it

calendar.calendarPush(Time, Priority, &Calendar::calendarEmpty);

But Visual Studio keeps to warn me with this error

argument of type "bool (Calendar::*)()" is incompatible with parameter of type "eventPointer *"

#include <iostream>
#include "Calendar.h"
using namespace std;
int main() {
cout << "Initializing ..." << endl;
double Time = 0.0;
int Priority = 0;
