Behaviour of hash when key is QPointer<QObject*>

[Zweistein]

Since your qHash Funktion returns an "uint" copy, i think the hash holds its old adresses. you can test it:

QHashIterator<QPointer<MyObject>, SomeObject*> i(hash);
 while (i.hasNext()) {
     i.next();
     cout << i.key() << ": " << i.value() << endl;
 }

QHashIterator<QPointer<MyObject>, SomeObject*> i(hash);
 while (i.hasNext()) {
     i.next();
     cout << i.key() << ": " << i.value() << endl;
 }

To copy to clipboard, switch view to plain text mode

I think it's a bad idea to have a QPointer in a hash as a key. Might be ok as a value, but definitely not as a key. The global qHash function caused immense pain in linking and it doesn't even have the qpointer facilities
