I tougth id fixed the issue you described to me in your house - and I think I did, but in the end I created another issue. The getter idea seems correct, sorry for the confusion.

Before I start coding, I have a question (which shows how little C++ I understand): What exactly does

		ProfileWidget2 *view = qobject_cast<ProfileWidget2*>(scene()->views().first());

(this is line 266 of divetooltipitem.cpp)?

How much overhead does this have? I hope, it does not create and initialise a whole ProfileWidget2, because all we need to do is

view->currentState == ProfileWidget2::PLAN

And we would do that (unless I somehow store the value somewhere) a lot of times (namely whenever the code differs between deco models).

Where is the call to sync? I placed a debugging message there and that was never printed.
