drag and drop from QTreeView

[Untersander]

I have a QTreeView initialized with

setDragEnabled(true);
setAcceptDrops(true);
setDropIndicatorShown(true);

then I use the startDrag, dragMoveEvent and dropEvent to handle the Items.

This works fine with Qt 4.0.1 but doesn't work anymore with the newer Qt versions:
startDrag is called but never dragMoveEvent.

I read in the forums that other people have the same problem, but they couldn't be helped.

You shouldn't need (and shouldn't use) any of those with QTreeView. You should use the model-view based approach for model-aware widgets.
