I am trying to embed a QWidget into a QGraphicsScene using addWidget, and it seems to be embedding successfully, but it is not drawing at all, and I am not sure why. Here's the code where I embed the QWidget:

Qt Code: 
  1. // JSL
  2. void QWorksheetDoc::addTable(DrawObjData *data, bool front, bool leaveSelected, char *theText)
  3. {
  4. 	if (worksheetView)
  5. 		{
  6. 		worksheetScene->clearSelection();
  7. 		QDatatable *table = new QDatatable();
  8. 		table->QDatatable::IDatatable(this);
  9. 		QGraphicsProxyWidget *theProxy = worksheetView->scene()->addWidget(table);
  10.  
  11. 		theProxy->setFlag(QGraphicsItem::ItemIsMovable);
  12. 		theProxy->setFlag(QGraphicsItem::ItemIsSelectable);
  13.  
  14. 		// JSL - install the common scene Event filter object.
  15. 	    theProxy->installSceneEventFilter(sceneDrawCommon);
  16. 		theProxy->setSelected(true);
  17.  
  18. 		if (front)
  19. 			bringToFront();
  20. 		if (leaveSelected == false)
  21. 			worksheetScene->clearSelection();
  22. 		worksheetView->show();
  23. 		}
  24. }
To copy to clipboard, switch view to plain text mode 

QDatatable descends from QTableView.

Here's the code where QDatatable paints. I added the frame, and the fill to try to see anything on the screen:

Qt Code: 
  1. //
  2. // JSL - paint
  3. //
  4. void QDatatable::paintEvent(QPaintEvent *event)
  5.  {
  6. 	QPainter	painter(this);
  7. 	//QRectF		rect = frameRect();
  8.  
  9. 	QTableView::paintEvent(event);
  10.  
  11. 	painter.setRenderHint(QPainter::Antialiasing);
  12. 	painter.setPen(Qt::darkGray);
  13. 	painter.drawRect(rect());
  14. 	painter.fillRect(rect(), QColor(224,424,224));
  15. }
To copy to clipboard, switch view to plain text mode 

If anyone has any idea why this is not working I would appreciate hearing about it. What I see is a white rectangle that seems to obey z ordering, but is not selectable, or movable, and doesn't render anything.
