It appears that the QML object that is created when assigning the source to the StatsView in the ui can be garbage collected and therefore destroyed and re-instantiated without our knowledge. So instead of trying to keep a pointer around, we end up looking up the object address when needed. We still ask the JS code to not garbage collect the object - but that clearly isn't enough to prevent it from being destroyed when the parent widget changes. Without this fix opening the statistics will crash with Qt6. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
