- // the size of its scrollable area according to the amount of content in scene that is rendered
- // offscreen.
- // 3) Set QWebPage's preferredContentsSize according to the size of QGraphicsView's viewport,
- // so WebCore properly lays pages out.
- //
- // On the other hand, when toggling resizesToContents OFF, we set back the default values, as
