python - How to find the parent of item when clicked in empty space PyQt4 QTreeWidget -

didn't quite know how word here go,

this part of program displays folders found in directory , subdirectorys in qtreewidget (it loads them fine) ability create new folders no matter depth in tree. example have directory:

data\examples\folders\ 

and right click in empty space in qtreewidget below folders branch, want ability create folder below directory becomes:

data\examples\folder\untitled\ 

i have context menu working cannot understand how implement way place new folder item @ specific depth not know parent of area clicked

here code (only retentive parts):

self.treelist = qtgui.qtreewidget() self.treelist.setheaderlabels(["name"]) self.treelist.setcontextmenupolicy(qtcore.qt.customcontextmenu) self.treelist.customcontextmenurequested.connect(self.opencontextmenu) 

and opencontextmenu function

def opencontextmenu(self,point):      addfolder = qtgui.qaction(qtgui.qicon("data\\icons\\folder.png"), "&new folder", self)     addfolder.triggered.connect(self.addfoldertolist)      item = self.treelist.itemat(point)      #current mouse pos      cpos = qtgui.qcursor()      #context menu      contextmenu = qtgui.qmenu(self)      #context menu actions      contextmenu.addaction(self.addfolder)      contextmenu.exec_(cpos.pos()) 

what want happen when addfolder action triggered folder created beneath parent of area clicked.
