[PyKDE] [PyQT]problem updating a QTreeView after model changes

[Oscar Cossu]

Hy all.
I use a QTreeView to show a QDomDocument object. Using drag & drop i makes
change to the DOM three.

The issue: when i send the signal to view to update, data goes corrupted,
but only in the view.

This is the code:

def dropEvent(self, event):
        oggetto=event.source()
        parent=oggetto.indexAt(event.pos()).parent()  ## this manage the
ModelIndex of target when drop

        NomeDest=parent.child(oggetto.indexAt(event.pos
()).row(),0).data().toString()
        DestId=self.getValoreCaratteristica(parent.child(oggetto.indexAt(
event.pos()).row(),1).data().toString(),"id") ## a function that parse the
node to find the specified Attributes (in this case "id")

        DragTargetElem=self.findNodeByTagNameID(NomeDest,DestId) ## this
return the QDomNode specified by his name and his id
        targetParent=DragTargetElem.parentNode()
        targetParent.insertBefore(self.view.startDragModelInd,
DragTargetElem) ##change the Dom layout

        oggetto.model().emit(QtCore.SIGNAL("layoutChanged()"))  ## HERE,
work but treeview display garbage text

        print DragTargetElem.ownerDocument().toString()     ##  used to
verify the Dom consistence



What error? treeview display  a Dom without the dragged/dropped node, also
the other node is doubled.
