How to pass slot as parameter?

whynoitwork

I don't understand how to do this like for example:

@void RequestMessage(SLOT *callback)
{
callback.Call(data);
}@

I want someone to be able to specify a function on which they get the callback.

SLOT is a "function":http://qt-project.org/doc/qt-5/signalsandslots.html#slots. It can either member of a class or standalone function.

If you need to pass a slot to another function then declare that another function with pointer to a slot-function as a parameter and then call that parameter. An example with member function:
@
class A
{
...
public slots:
void foo(int);
...
};

void otherFunction(void (A::*param)(int))
{
*param(10);
}
