Member Function Documentation

void QMap::erase(const Key & key)

Use remove(key) instead.

iterator QMap::insert(const Key & key, const T & value, bool overwrite)

Use the two-argument insert() overload instead. If you don't want to overwrite, call contains() beforehand.

For example, if you have code like

QMap<QString, int> map;
map.insert("delay", 30000, false);

you can rewrite it as

QMap<QString, int> map;
if (!map.contains("delay"))
    map.insert("delay", 30000);

iterator QMap::remove(iterator it)

Use erase(it) instead.

iterator QMap::replace(const Key & key, const T & value)

Use remove() then insert().
