adding QGraphicsItem to multiple scenes

[forrestfsu]

I've been attempting a different solution for part of my problem. Perhaps the following can work? To display the same QGraphicsItemGroup on different views with a different background, can I reimplement:

QGraphicsView::drawBackground(QPainter *painter, const QRectF &rect)

I was able to get it to display a background on all the views:

void QGraphicsView::drawBackground(QPainter *painter, const QRectF &rect)
{
  painter->drawEllipse(10, 10, 10, 10);
}

void QGraphicsView::drawBackground(QPainter *painter, const QRectF &rect)
{
  painter->drawEllipse(10, 10, 10, 10);
}

To copy to clipboard, switch view to plain text mode 

However, I need to make it unique for each view. I want something like this:

void QGraphicsView::drawBackground(QPainter *painter, const QRectF &rect)
{
 if (this->ui.view1)
  painter->drawEllipse(10, 10, 10, 10);
 else if (this->ui.view2)
  painter->drawEllipse(20, 20, 20, 20);
 else if (this->ui.view3)
  painter->drawEllipse(30, 30, 30, 30);
}

void QGraphicsView::drawBackground(QPainter *painter, const QRectF &rect)
{
 if (this->ui.view1)
  painter->drawEllipse(10, 10, 10, 10);
 else if (this->ui.view2)
  painter->drawEllipse(20, 20, 20, 20);
 else if (this->ui.view3)
  painter->drawEllipse(30, 30, 30, 30);
}

To copy to clipboard, switch view to plain text mode 

However, I can't seem to figure out how to code the if statement to recognize a specific graphics view on my form...any tips? I've tried:

if (this->ui.view1)
 if (this->TheForm::ui.view1)

if (this->ui.view1)
 if (this->TheForm::ui.view1)
