[PyQt] Drag & Drop with QTreeWidget

[NARCISO, Rui]

Hi all

I'm trying to implement Drag & Drop in my QTreeWidget based GUI but it is not clear to me how to proceed (after having read the Doc and googled it).

I have several question (tree = QTreeWidget())
 1) I have activated:
	tree.setSelectionMode(QAbstractView.ExtendedSelection)
    yet before I would just keep the mouse pressed and slide over the selection I wanted but now that is not possible. Is there a way to maintain such behaviour and force that the drag is only performed on a second click over the selection ?

 2) how do I force a certain QTreeWidgetItem NOT to accept drops ?

 3) I have a specific tree:
       RootItem
             |
             | ---  Campaign1
             |            |
             |            |---- Folder1
             |                      |
             |                      |------ Calc1            path1      (where path1= /home/ .... /Folder1/calcname1 
             |                      |------ Calc2            path2      (where path2= /home/ .... /Folder1/calcname2
             |
             | ---  Campaign2

       So what I would like would be to drag only items of name "calc*" to nodes of type "campaign" (ex: Campaign2) and when doing so create the sub-node "Folder1" if it does not exist within "campaign" and put the dragged items under "folder1" (and not "campaign" where they were dropped). How to do this ? Do I do this in a dropEvent? In a dropEventAction ?

Thank you all for your help, I know it's not easy to answer this sort of hypothetic questions.

Cheers
Rui
