memory leaks and deleting a QMap

[d_stranz]

More like this:

QList< Something * > things = a_map.values();
foreach( Something * thing, things )
{
    delete thing;
}

QList< Something * > things = a_map.values();
foreach( Something * thing, things )
{
    delete thing;
}

Edit: although upon reading the docs, it looks like your code would accomplish the same thing. I am more familiar with std:: map<>, where the iterator returns an std:: pair<> containing the key and value.

Definitely iterating over the map.
Iterating over the values requires two iterations: one for creating the list of values and the the actual loop.

In any case: http://doc.qt.io/qt-5/qtalgorithms.html#qDeleteAll-1
