How to set Model for QListWidget
Is there a way to setModel for a QListWidget? I am getting AttributeError: QListWidget.setModel is a private method
about this:
class Model(QtCore.QAbstractListModel):
def __init__(self):
QtCore.QAbstractListModel.__init__(self)
self.items=[]
def rowCount(self, parent=QtCore.QModelIndex()):
return len(self.items)
def flags(self,index):
return QtCore.Qt.ItemIsEditable
view=QtGui.QListWidget()
viewModel=Model()
view.setModel(viewModel)

I just would like to finish @ Achayan's answer: if you look at the Qt documentation you can find a very good tutorial explaining exactly the difference between
- via standard widgets
- using Model / View
In the first case, standard widgets own a version of the data , which may seem easier to work with and manage at a glance, but can lead to a synchronization problem>. Indeed, if the widget(which is a view) owns its own version of the data, you need to be sure that this data is in sync with the database. And what else if you have, say, 2 or 3 other widgets of the model of the same (example: table, list and dropdown representing the same object), so you have four versions of the data ...
The second option is better if you want a more decoupled and flexible implementation: the model is really "simple" and has no data. It just interacts with the model, so it must implement this interface ( QAbstractItemModel
).
In your case: QListWidget
is the "standard widget" and QListView
is the implementation representation of the Model / View.
