Can you use a pointer as a key in a QHash?

Sure. You don't even need to provide a qHash() overload because one is generated for you by the template. Why do you ask?

Just wanted to make sure.
Had to decide whether to use a QMultiHash of values to Node ptrs or a QHash of Node ptrs to values.
The second one allows me to remove a row without having to iterate through the results of a find.
Thanks for that.
