Problem regarding C++ STL

There is no difference between find() and findRef() if you have a vector of pointers.

Please don't ask the same question in different section.

Of course there is.
Diffrenent pointers can point to different objects that have same value.

But still, if the value is a pointer, there is no difference, since find() doesn't dereference pointers.

I guess that for Qt3 with QPtrList it might make a difference. Of course STL doesn't support dedicated lists for pointers, so to port the same behaviour to STL, one has to provide a custom compare functor.

Can you please visualize with an example??
