bool QgsFeatureListModel::setDisplayExpression ( const QString expression )

Parameters

expression A QgsExpression compatible string.

Returns: true if the expression could be set, false if there was a parse error. If it fails, the old expression will still be applied. Call parserErrorString() for a meaningful error message.
