@AnneRanch said in What "type" is "pos()"?:

event->pos();

Of what type is event and what Qt version do you use? If you know the type of event and your Qt version you can search the Qt documentation for it.

Hi @AnneRanch,

As @Christian-Ehrlicher replied, it depends on what type event is, and the version of Qt.

Given you're naming the result dragStartPosition, I'm guessing event is either derived from QPointerEvent, QMouseEvent, or QDropEvent (including QDragEnterEvent). For all of those, *::pos() returns QPoint on Qt5, but in Qt6 the function is *::position() instead, and returns QPointF. ie

#if QT_VERSION < QT_VERSION_CHECK(6, 0, 0)
const QPoint dragStartPosition = event->pos();
#else
const QPointF dragStartPosition = event->position();
#endif

To be any more specific than that, you'll need to tell use what type event is, and the Qt version.

Cheers.

PS You could also use auto.
