Reordering pixmap items in a QGraphicsScene

Hello All,

I'm working on an application where I need to have the user sort a set of images into the proper order. I'm trying to figure out how to sort/reorder pixmap items in a QGraphicsScene within a QGraphicsLinearLayout. This would be similar to dragging an application to the dock on a Mac. if I drag one pixmap item between two others, a space would open up to drop it in. I apologize if this question has been ask before. I have searched quite a bit. Perhaps I'm not searching for the correct thing. Anyway, I am not quite sure what would be the best approach to accomplish this. I guess it could be some kind of drag and drop based thing, or possibly just based on handling mouse events. This is the first time I have used the QGraphicsView framework. Any suggestions that would point me in the right direction would be much appreciated.

Thanks,
-G
