Detailed Description

template<class T, class IS = QDataStream, class OS = QDataStream>
class quark::gui::AbstractTableModel< T, IS, OS >

An abstract base class for table data models, i.e., models in which every row represents an instance of the same type of object, and each column represents a field of that object.

Subclasses must implement getFieldValue() to map members of an object to fields in the table.

This class does not specify the data structure for storing the model's contents. Subclasses must implement itemCount(), indexOf(), getAt(), takeAt(), insertAt(), and removeAll() to provide a storage and retrieval mechanism for the items. See BasicTableModel for a default implementation that stores items in a QVector.

If the model supports drag and/or drop, data streams of the specified type will be instantiated to serialize/deserialize the dragged objects.

Template Parameters

T	The type of the objects contained in this model. The class must implement the less-than operator.
IS	A class for deserializing objects of type T.
OS	A class for serializing objects of type T.
