QList <QPointF> markers; markers.append (QPointF (getLat (), getLon ())); QList <QPointF> :: iterator i; for (i = markers.begin(); i != markers.end(); ++i) std :: cout << *i << endl; Gives me:
error: no match for 'operator<<' in 'std::cout << i.QList::iterator::operator* with T = QPointF'
You can use qDebug().
QList<QPointF> markers; markers.append(getLat(), getLon()); QList<QPointF>::iterator i; for (i = markers.begin(); i != markers.end(); ++i) qDebug() << *i; Remember to include QDebug:
#include <QDebug> A foreach loop would be simplier for that:
Q_FOREACH( QPointF p, markers ) { qDebug() << p; } AFAIK QPointF class by itself does not have a << overload operator. You can either re-implement it and overload the operator yourself or more simply just try to output the coordinates myPoint.x() and myPoint.y().
