It's not needed, as drop events should go to the children first, who are on top.
I put it in anyway because t doesn't hurt and might help in the (corner) case of an item
not accepting the move event but accepting a drop (Could be i'm mistaken here though,
don't know if qt even generates drop events if a dragmove wasn't accepted before)

yes, that would then give the clear visual indication about the remaining area,
wher an applet can not be dropped.
