hm. ok ... even though we can't have negative times here =) internally it was 
a uint until i changed what i was storing there, but changing the API to 
reflect what is there now is fine =)

sure =)

are you sure? it's set in DataContainer::Private::signalRelay, is it not?

there is a reason the SignalRelay class is in a _p.h file ;) external usage of 
this class should not need to know about SignalRelay at all

sure it is; well at least it doesn't crash doing so ... and the real issue for 
calling disconnectVisualization on destroyed() is to remove the SignalMapper 
from our data structures. QObject disconnect()s automatically on destruction 
(obviously) but DataContainer needs to remove it from its record keeping

except that now you've made it impossible to call disconnectVisualization 
directly. this part of the patch is wrong.

whoops, yes... silly capital letters.
