TheQAbstractTableModel 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 thanQAbstractItemModel, it is not suitable for use with tree views, although it can be used to provide data to aQListView. If you need to represent a simple list of items, and only need a model to contain a single column of data, subclassing theQAbstractListModel may be more appropriate.
TherowCount() andcolumnCount() functions return the dimensions of the table. To retrieve a model index corresponding to an item in the model, useindex() and provide only the row and column numbers.
When subclassingQAbstractTableModel, you must implementrowCount(),columnCount(), anddata(). Default implementations of theindex() andparent() functions are provided byQAbstractTableModel. Well behaved models will also implementheaderData().
Editable models need to implementsetData(), and implementflags() to return a value containingQt::ItemIsEditable.
Models that provide interfaces to resizable data structures can provide implementations ofinsertRows(),removeRows(),insertColumns(), andremoveColumns(). When implementing these functions, it is important to call the appropriate functions so that all connected views are aware of any changes:
Note:Some general guidelines for subclassing models are available in theModel Subclassing Reference.
