From: kb Date: Fri, 9 Mar 2012 11:29:09 +0000 (+0100) Subject: Disconnect slots from the old sourcemodel in QIdentityProxyModel X-Git-Tag: qt-v5.0.0-alpha1~309 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fae4a2555a9402e8cecf67242b29dca624cc61e8;p=profile%2Fivi%2Fqtbase.git Disconnect slots from the old sourcemodel in QIdentityProxyModel When setting a new sourcemodel QIdentityProxyModel::setSourceModel tries to disconnect from signals belonging to the NEW model instead of from the existing sourceModel(). QIdentityProxyModel thus receives signals from both the old model(s) and the new model. This results in ASSERTS triggering in various slots, for example: "Q_ASSERT(topLeft.isValid() ? topLeft.model() == model : true);" in QIdentityProxyModelPrivate::_q_sourceDataChanged.
