Qt How to use connect between incompatible signal and slot

In this I want to call a function, that function will receive a point . But this function should be invoked by a timer's timedout signal. Can anybody say how to achieve this. Below is the required/error code

Point p(a,b);

connect(timer,SIGNAL(timedout()),this,startDestruction(p));

Can anybody say how to achieve this?

Create a method to use as an intermediate slot, like this.

Point p(a,b);
connect(timer, SIGNAL(timedout()), this, q);

q() {
    startDestruction(this->p)
}
