Detailed Description

The QGraphicsSceneResizeEvent class provides events for widget resizing in the graphics view framework.

Since: 4.4

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.
