ListModel[T]

ListModel is a Model that stores its data in a Python list.

Construct a ListMode from an iterable (such as a list itself). Use append to add items to the model, and use the del statement to remove items.

Any changes to the model are automatically reflected in the views in UI they’re used with.

Bases: Model[T]
