Resize whenever the GraphicsView is resized). Sets a QGraphicsWidget to automatically fill the entire view (the item will be automatically To make the background transparent, use background=None. To use the defaults specified py tConfigOption, use background=’default’. Set the background color of the GraphicsView. Note that this will only affect items that do not specify their own antialiasing options. This may result in a significant performance increase.
