Hi,
I am trying to insert a series of qgraphicsviews into the cells of a dynamically expanded qgridlayout.

Here is a bit from the grid class.

Qt Code: 
  1. qTrackGrid::qTrackGrid(qDocumentView *parent)
  2. 	: QWidget(parent),
  3. 	count(0)
  4. {
  5. 	grid = new QGridLayout(this);
  6. 	setLayout(grid);
  7. }
  8.  
  9. qTrackGrid::~qTrackGrid()
  10. {
  11. 	// delete everything
  12. 	for(int cc = 0; cc < count; cc++)
  13. 		delete views[cc];
  14. 	delete grid;
  15. }
  16.  
  17. void qTrackGrid::addTrackView(vwd_SV SV)
  18. {
  19. 	// add a new qTrackView to the next available position in the grid
  20. 	// hear we are enforcing that the column width be a maximum of 2
  21. 	int cRow = grid->rowCount();
  22. 	int cCol = grid->columnCount();
  23. 	int row = count / 2;
  24. 	int col = count % 2;
  25. 	qTrackView* tv = new qTrackView(this, SV);
  26. 	tv->setVisible(true);
  27. 	grid->addWidget(tv->viewport(), row, col);
  28. 	views.append(tv);
  29. 	qDebug() << grid->cellRect(row, col);
  30. 	count++;
  31. }

I would like to use something like the following code in the qTrackView class I have inserted into the grid to make sure that the image scales and displays according to the current size of the qTrackGrid widget.

Qt Code: 
  1. qTrackView::qTrackView(QWidget *parent, vwd_SV iSV)
  2. 	: QGraphicsView(parent),
  3. 	SV(iSV),
  4. 	buff(NULL),
  5. 	size(0)
  6. {
  7. 	// create the scene
  8. 	scene = new QGraphicsScene;
  9. 	setScene(scene);
  10.  
  11. 	// update the view
  12. 	updateView();
  13. }
  14.  
  15. void qTrackView::resizeEvent(QResizeEvent *event)
  16. {
  17. 	fitInView(scene->sceneRect(), Qt::IgnoreAspectRatio);
  18. }
To copy to clipboard, switch view to plain text mode 

I dont seem to be getting the resizing working as it would if the QGraphicsView object was inserted into the the widget without it being a cell of a QGridLayout.

I am setting up the qTrackView class with a QGraphicsScene as you can see from the constructor.

Its obvious that I am missing something just havent got my head around it yet.

Thanks,
Dave...
