From 2d750192e73244f5b4ad6b451f264728d42669be Mon Sep 17 00:00:00 2001 From: Gabriel de Dietrich Date: Mon, 26 Oct 2009 15:53:47 +0100 Subject: Fixed crash when setting header data in QSqlQueryModel. The crash (Q_ASSERT_X failure) happened when a proxy model was being attached to the QSqlQueryModel, and no query was set yet. The headerDataChanged() signal was being received by the proxy model who wouldn't check its "proxyfied" data bounds. The patch introduces a behaviour change. However, this change makes the usage of QSqlQueryModel::setHeaderData() to be more in accordance with the current documentation, and to behave in the same way as for QStandardItemModel, QTreeModel, and QTableModel.
