In this case, it seems it might be doing the wrong thing. The blocking class is what's needed instead.

Probably yes. You'd do a

void ObjectsPanel::_setCompositingValues(SPItem *item) { //Block theconnections to avoid interference SignalBlockerb1(*_opacityConnection); SignalBlockerb2(*_blendConnection); SignalBlockerb3(*_blurConnection);

// ... }

At the end of the scope, these objects are destructed inreverse order, so this is just fine. This code is blocking around a lot, I'm not sure whetherall of this is necessary. Maybe there are better solutions to this.
