Example
If a singleshot timer is required, it is quiet handy to have the slot as lambda function right in the place where the timer is declared:
QTimer::singleShot(1000, []() { /*Code here*/ } );
Due to this Bug (QTBUG-26406), this is way is only possible since Qt5.4.
In earlier Qt5 versions it has to be done with more boiler plate code:
QTimer *timer = new QTimer(this);
timer->setSingleShot(true);
connect(timer, &QTimer::timeout, [=]() {
/*Code here*/
timer->deleteLater();
} );
