| QGraphicsSceneResizeEvent()

## Detailed Description

A QGraphicsWidget sends itself a QGraphicsSceneResizeEvent immediately when its geometry changes.

It's similar to QResizeEvent, but its sizes, oldSize() and newSize(), use QSizeF instead of QSize.

See also QGraphicsWidget::setGeometry() and QGraphicsWidget::resize().
