Need a dragPixmap() virtual function in QAbstractItemView.

When I want to set my custom pixmap for dragging in a QAbstractItemView subclass, I have to override

  void QAbstractItemView::startDrag(Qt::DropActions supportedActions)

because the default pixmap was created in the default implementation of this method, it cannot be altered in subclasses without overriding the method and executing a QDrag manually.

What I suggest is to put the default pixmap into a virtual protected function like QPixmap dragPixmap(), which when overriden, we can use to return our custom pixmaps for dragging.

Thanks for reading!
