Hi Christian, thank you for your input.
BaseRenderer* sender = interactionEvent->GetSender(); is what I am
aiming for. I want to know how to compare the sender (which can be any
of my render windows) to the current one receiving the signal.
I am looking for something that represents the following test:
if ( sender->getRenderWindow () == this->renderwindow ) then ok!
else ignore!
Best,
Miguel
