Removing items from a QList of pointers

问题

I have a QList of pointers to objects.

QList <MyObj*> mylist;

I add to the list as follows

mylist.append(new MyObj(1));
mylist.append(new MyObj(2));

So far so good.

So for exampple if I have a MyObj object and I want to search the list for a match how do I do it?

The indexOf memeber funcion requires that I have the comparison operator for MyObj, but MyObj does not have one.

So given a MyObj object, what is the best way to see if it is contained in the list?

Regards
