Status: New Owner: ---- New issue 3903 by fernando...@gmail.com: Removing the Globals World, ActiveHand and ActiveEvent. As well as direct references to WorldState. http://code.google.com/p/pharo/issues/detail?id=3903 All the senders must go thru the default UIManager. There's no need for the globals anymore, since all UI related requests should go thru the UIManager now. I will go thru all the uses and replace them with UIManager default activeWorld UIManager default activeHand UIManager default activeEvent I believe this will make a lot easier to install a different UIManager, or even the NonInteractive. My main motivation is to simplify the adoption of SimpleMorphicUIManager, in order to install/uninstall Morphic or SimpleMorphic. Also, to remove Globals is always a good design.
