Problem with removeOne

[zgulser]

Hi,

I have such a list;



QList<QPointer<Contact>> myList;


I populated this list and it seems ok. But When I want to remove a contact like;



bool success = _participantList.removeOne(contact);


it doesn't remove it. And it's size remains the same.

Any ideas?

myList != _participantList ?

Also, what is "contact"? Does it have a comparison operator defined?

[zgulser]

Sorry for that,

Yes myList = _participantList.

No. I didn't define one but it derived from QObject.

[wysota]

Yes myList = _participantList.

"=" or "=="? Is it the same list (meaning you used a wrong variable name) or is it a copy of the original list?


I didn't define one but it derived from QObject.

I just noticed we're talking about pointers. Are you passing the same pointer that is in the list or a different one that simply points to the same QObject?

[zgulser]

No. There is no myList. I just wrote it to tell my problem. It should be;

QList<QPointer<Contact>> _participantList;

Your second claim is most probably the reason. I'm going to have a quick check now.

See what QList::contains() returns.
