Description
In the documentation of QListIterator (https://doc.qt.io/qt-5/qlistiterator.html#details)
we can see :
QList<float> list; ... QListIterator<float> i(list); while (i.hasNext()) qDebug() << i.next();
or
QListIterator<float> i(list); i.toBack(); while (i.hasPrevious()) qDebug() << i.previous();
These codes fail depending on the debug level. If "*.debug=false", methods next() or previous() are not executed in the examples above. And the loop is infinite if there is at least one element.
So we have to prefer :
QList<float> list; ... QListIterator<float> i(list); while (i.hasNext()) { float value = i.next(); qDebug() << value; }
and
QListIterator<float> i(list); i.toBack(); while (i.hasPrevious()) { float value = i.previous() qDebug() << value; }
