1   QDate birthday(2010,10,13);
2
  QDate today;
3
  today = QDate::currentDate ();
4
  int daysold = birthday.daysTo (today);
5
  ui->lcdNumber_2->display (daysold);

说明:

int QDate::daysTo ( const QDate & d ) const

Returns the number of days from this date to d (which is negative if d is earlier than this date).

QDate d1(1995, 5, 17);  // May 17, 1995 
QDate d2(1995, 5, 20);  // May 20, 1995 
d1.daysTo(d2);          // returns 3 
d2.daysTo(d1);          // returns -3
