How is the qabstractlistmodel class used in Qt?

The QAbstractListModel class provides an abstract model that can be subclassed to create one-dimensional list models. More… QAbstractListModel provides a standard interface for models that represent their data as a simple non-hierarchical sequence of items. It is not used directly, but must be subclassed.

Which is an example of a qstringlist based model?

For example, we could implement a simple read-only QStringList -based model that provides a list of strings to a QListView widget. In such a case, we only need to implement the rowCount () function to return the number of items in the list, and the data () function to retrieve items from the list.

Which is better qabstractitemmodel model or tree view?

Since the model provides a more specialized interface than QAbstractItemModel, it is not suitable for use with tree views; you will need to subclass QAbstractItemModel if you want to provide a model for that purpose. If you need to use a number of list models to manage data, it may be more appropriate to subclass QAbstractTableModel instead.

How to create simple models in Qt core?

Simple models can be created by subclassing this class and implementing the minimum number of required functions. For example, we could implement a simple read-only QStringList -based model that provides a list of strings to a QListView widget.

How to create editable list in Qt core?

For editable list models, you must also provide an implementation of setData (), and implement the flags () function so that it returns a value containing Qt::ItemIsEditable. Note that QAbstractListModel provides a default implementation of columnCount () that informs views that there is only a single column of items in this model.
