I came up with a similar idea. Looking at the C++ code I realized that QGraphicsItemGroup already provides bounding box caching. Simply wrapping my custom graphics items in item groups should do the trick. Unfortunately, when trying to add a custom graphics item to a item group I end up with the following error: QtJambiTypeManager::convertInternalToExternal: Cannot convert to type 'com/trolltech/qt/gui/QGraphicsItem$ConcreteWrapper' from 'QGraphicsItem*' Any idea where this might come from?
