How to return the keys of a map in a vector

[Rumo]

Hi,

my method has the following code:

const QVector<unsigned int> CLandTypes::getLandTypes()
{
    QVector<unsigned int> returnValue;
 
    for(QMap<unsigned int, CLandType>::iterator mapLandTypeIterator = (QMap<unsigned int, CLandType>::iterator)d->LandTypes.begin(); mapLandTypeIterator != (QMap<unsigned int, CLandType>::iterator)d->LandTypes.end();++mapLandTypeIterator)
    {
        returnValue.push_back(mapLandTypeIterator.key());
    }
    return returnValue;
}

const QVector<unsigned int> CLandTypes::getLandTypes()
{
    QVector<unsigned int> returnValue;

    for(QMap<unsigned int, CLandType>::iterator mapLandTypeIterator = (QMap<unsigned int, CLandType>::iterator)d->LandTypes.begin(); mapLandTypeIterator != (QMap<unsigned int, CLandType>::iterator)d->LandTypes.end();++mapLandTypeIterator)
    {
        returnValue.push_back(mapLandTypeIterator.key());
    }
    return returnValue;
}

How can it be done in a better way?
