[Interest] problems with drag event in QListView with delegate in edit mode

[Frank Rueter | OHUfx]

Same issue with the context menu. I have to right lick twice before it 
opens.
I have been trying to set focus and various states on the view but still 
can't get it right.
Any help would be very much appreciated.

Cheers,
frank
