Detailed Description

The QHoverEvent class contains parameters that describe a mouse event.

Mouse events occur when a mouse cursor is moved into, out of, or within a widget, and if the widget has the Qt::WA_Hover attribute.

The function pos() gives the current cursor position, while oldPos() gives the old mouse position.
