Putting a QGraphicsScene into QMdiSubWindow

[marcel]

Create the scene on the heap. In your code, the scene gets deleted as soon as the function exists.

Thanks.

Ok, tried that, this is what I now have :

CanScene* pcanScene = new CanScene(this);
	pcanScene->setSceneRect( QRectF( 0, 0, 5000, 5000 ) );
	pcanScene->setBackgroundBrush(Qt::blue);
	QGraphicsView view(pcanScene);
 
	QMdiSubWindow* subWindow = m_pworkspace->addSubWindow( &view );

CanScene* pcanScene = new CanScene(this);
	pcanScene->setSceneRect( QRectF( 0, 0, 5000, 5000 ) );
	pcanScene->setBackgroundBrush(Qt::blue);
	QGraphicsView view(pcanScene);

	QMdiSubWindow* subWindow = m_pworkspace->addSubWindow( &view );

To copy to clipboard, switch view to plain text mode 

Still not blue background and paint event not being called?
