Another approach that might be more general but hard to apply to your situation is to use the Connections element for the signal connections. You can set the target to null when the item is not visible, and then back to the intended target when the item is visible. This may not work for the automatic connections set up by models though. -- Alan Alpert Software Engineer Nokia, Qt Development Frameworks _______________________________________________ Qt-qml mailing list [email protected] http://lists.qt.nokia.com/mailman/listinfo/qt-qml
