TypeError: argument 1 of QScrollView.removeChild() has an invalid type
That's because removeChild() is a QScrollView method. You can call this
method because QListView inherits it from QScrollView, but it's not the
method you're looking for.  > 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?  You need to call your QListView instance's
takeItem() method with the item you want to remove as the argument.
Hope this helps,  David
