<dd><p>Re-implementation of QGraphicsView that removes scrollbars and allows unambiguous control of the

viewed coordinate range. Also automatically creates a QGraphicsScene and a central QGraphicsWidget
|

that is automatically scaled to the full view geometry.</p>

automatically updates when the view is resized. This can be overridden by setting

autoPixelRange=False. The exact visible range can be set with setRange().</p>

enabled via enableMouse().</p>
