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,
