[Qt-interest] QMultiHash operator== not working as expected

[Christian]

Hi,

well im not mixing value and key. I have keys that are mapped to
multiple values and therefore i used MultiHash. The insert method of
QmultiHash does not replace. It creates a new entry (as stated in the
documentation). You can see that because the size of both hashes is 2.
So i think my problem still remains.

Best Regards
Christian

The output is correct, the problem is you are mixing keys and values.
The 
first parameter of insert is the key, not the value.

If you do:

hash1.insert("a", 1);
hash1.insert("a", 2);
hash2.insert("a", 2);
hash2.insert("a", 1);

Then you are replacing the corresponding value in the hash since both
have the 
same key.
