Detailed Description

\inmodule QtCore

The QAbstractListModel class provides an abstract model that can be subclassed to create one-dimensional list models.

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.

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.

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. 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.

Since the model represents a one-dimensional structure, the rowCount() function returns the total number of items in the model. The columnCount() function is implemented for interoperability with all kinds of views, but by default informs views that the model contains only one column.
