How do I sort a QList of QDateTime*?

Question

How do I sort a QList of QDateTime* objects by the value of the QDateTime object?

If you want to sort by the content of the QDateTime, and not the pointer values, then you should say so. Otherwise the trivial answer is simply `qSort(list)`; — rohanpm, Apr 18 '11 at 01:50
My fault, I want to sort by the value, I've edited the question — Jon, Apr 18 '11 at 02:04
There is no need to handle QDateTime edits as pointers, better use a QList. — Frank Osterfeld, Apr 18 '11 at 06:26

You can use qSort with your own comparison function:

#include <QtAlgorithms>

bool dtcomp(QDateTime* left, QDateTime *right) {
  return *left < *right;
}

QList<DateTime*> dtlist = ...;
qSort(dtlist.begin(), dtlist.end(), dtcomp);
