[Qt-interest] QTreeView Drag&Drop issue

[Sylvain Pointeau]

Hi David,
Thanks for your answer,
I have absolutely no problem in my code,
I am using a abstractModel with my QTreeView but
the thing is that the cursor is always the icon (+) even if I press the key
"CMD" (to only move the item)

this bug is really annoying as it show a bad indication to the users ...

do you see what I mean?

Cheers,
Sylvain
