The QPropertyAnimation class animates Qt properties.

The QPropertyAnimation class animates Qt properties.

QPropertyAnimation interpolates over Qt properties. As property values are stored in QVariants, the class inherits QVariantAnimation, and supports animation of the same variant types as its super class.

A class declaring properties must be a QObject. To make it possible to animate a property, it must provide a setter (so that QPropertyAnimation can set the property's value). Note that this makes it possible to animate many of Qt's widgets.

Reference: https://doc.qt.io/qt-5/qpropertyanimation.html
