QMimeData * QTableModel::mimeData ( const QModelIndexList & indexes) const
overridevirtual

Returns an object that contains serialized items of data corresponding to the list of indexes specified.

The format used to describe the encoded data is obtained from the mimeTypes() function. This default implementation uses the default MIME type returned by the default implementation of mimeTypes(). If you reimplement mimeTypes() in your custom model to return more MIME types, reimplement this function to make use of them.

If the list of indexes is empty, or there are no supported MIME types, \nullptr is returned rather than a serialized empty list.

QStringList QTableModel::mimeTypes ( ) const
overridevirtual

Returns the list of allowed MIME types.

By default, the built-in models and views use an internal MIME type: {application/x-qabstractitemmodeldatalist}.

When implementing drag and drop support in a custom model, if you will return data in formats other than the default internal MIME type, reimplement this function to return your list of MIME types.

If you reimplement this function in your custom model, you must also reimplement the member functions that call it: mimeData() and dropMimeData().

The dataChanged() signal should be emitted if the data was successfully set.

The base class implementation returns {false}. This function and data() must be reimplemented for editable models.
