Removing an item from a QListView in PyQt

[Svenn Bjerkem]

Hi,

I am looking for a bit more elaboration on the problem of deleting
elements from a QListsView. I know this is a tricky problem with
references, but I have not been able to extract enough knowledge from
the documentation to solve a specific problem:

In a dialog I have a QListView called referenceList. Entries are added
and deleted from this list with buttons addButton and removeButton
connected with sockets:

----
class IdeaInputBase(QDialog):
    def __init__(self,parent = None,name = None,modal = 0,fl = 0):
        QDialog.__init__(self,parent,name,modal,fl)


self.connect(self.addButton,SIGNAL("clicked()"),self.addNewReferenceSlot)

self.connect(self.removeButton,SIGNAL("clicked()"),self.removeReferenceSlot)
...
----
class IdeaInput(IdeaInputBase):
	def __init__(self):
		IdeaInputBase.__init__(self)

	def addNewReferenceSlot(self):
		self.referenceList.insertItem(QListViewItem(self.referenceList, "An
Item"))

	def removeReferenceSlot(self):
		print "selected has address %s" % (self.referenceList.selectedItem())
		self.referenceList.removeChild(self.referenceList.selectedItem())
----
Adding Items by pressing the addButton works fine. I then select one of
the list elements and press the removeButton. This is the output I get.

selected has address <qt.QListViewItem object at 0x1c98f0>
Traceback (most recent call last):
  File "./idea_input.py", line 20, in removeReferenceSlot
    self.referenceList.removeChild(self.referenceList.selectedItem())
TypeError: argument 1 of QScrollView.removeChild() has an invalid type

I see that I have an address of a QListViewItem, but I am not able to
delete it. What am I obviously doing wrong here?

Kind regards,
