I created my QDeclarativeItem, and created my root one in a VisualItemModel where and I have that properly showing up in the GridView. I am really confused in the VisualItemModel what my parent is. My impression is that if I could append the newly created QDeclarativeItem to the children property that I would be okay. But like you said finding the proper parent is the key issue here. At the end of the day I can get one of the items into the UI, but where I get killed is when the bound QDeclarativeItem creates a new QDeclarativeItem that is to be added to the same container that the original one is in.

Yeah, that is my assessment too. Thanks! _______________________________________________ Qt-qml mailing list Qt-qml@qt.nokia.com http://lists.qt.nokia.com/mailman/listinfo/qt-qml
