详细描述
The QGraphicsSceneResizeEvent class provides events for widget resizing in the graphics view framework.
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.
参见 QGraphicsWidget::setGeometry() and QGraphicsWidget::resize().
