I am running this solution on my notebook, with 1366 x 768 resolution. If i want to use entire screen space, i have to give size to my <code>QGraphicsWebView</code> (line with comment added at the end) and to my <code>QGraphicsView</code> that lies in my <code>MainWindow.ui</code>. I want to remove this static part, and make it dynamic.</p>
