[Qt-interest] How to detect drag drop on a QListWidget (Signal?)

[Matthias Pospiech]

I could find out that drag and drop can be enabled using this code:
ui->listWidget_MacroCommands->setDragEnabled(true);
ui->listWidget_MacroCommands->setDragDropMode(QAbstractItemView::InternalMove);

However I can not find any signal which indicates that such a move has 
happened.
All I want to know is which index moved to which different index.

I have looked at some examples, but all I can see is events, which dont 
tell me the
indexes which has changed. And that I must derive a class which I really 
do not want
to do.

Can somebody give me a hint where to learn how to use drag and drop the way
I want to use it - I only want to be able to rearrange elements in a 
QListWidget.
