public abstract class QAbstractTableModel
- extends QAbstractItemModel
The QAbstractTableModel
class provides an abstract model that can be subclassed to create table models. QAbstractTableModel
provides a standard interface for models that represent their data as a two-dimensional array 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, although it can be used to provide data to a QListView
. If you need to represent a simple list of items, and only need a model to contain a single column of data, subclassing the QAbstractListModel
may be more appropriate.
The rowCount()
and columnCount()
functions return the dimensions of the table. To retrieve a model index corresponding to an item in the model, use index()
and provide only the row and column numbers.Subclassing
Note: Some general guidelines for subclassing models are available in the Model Subclassing Reference.
When subclassing QAbstractTableModel
, you must implement rowCount()
, columnCount()
, and data()
. Default implementations of the index()
and parent()
functions are provided by QAbstractTableModel
. Well behaved models will also implement headerData()
.
Editable models need to implement setData()
, and implement flags()
to return a value containing Qt::ItemIsEditable.
Models that provide interfaces to resizable data structures can provide implementations of insertRows()
, removeRows()
, insertColumns()
, and removeColumns()
. When implementing these functions, it is important to call the appropriate functions so that all connected views are aware of any changes:
