Issue using setDragDropMode( QAbstractItemView::InternalMove ) on a QListWidget

[AndyBrice]

I call setDragDropMode( QAbstractItemView::InternalMove ) on a QListView, so you can drag the list into a different order. When I detect a drop has happened it waits 2 seconds to see if there are any more drops, if not the changes are committed. It works fine except when the user is half way through a second drag when the 2 seconds from the first drag is up. It all then gets messy.

Is there any way to detect that an internal move is in progress on the QListView?

I tried using eventFilter() and mousePressEvent(), mouseReleaseEvent() etc, but I couldn't work out if the mouse had been released outside the QListWidget.

In the end I went with checking delaying the update until

QApplication::mouseButtons() == Qt::NoButton;

It's a bit inelegant, but it seems to work.
