Pharo: (Multi) Select in World by dragging

January 19th, 2011 2 comments

WorldState easySelectingWorld: true.

To make things easier and more obvious, I’ve added a setting for this and submitted it to the Pharo inbox.

Multiple Worlds for Pharo

January 18th, 2011 No comments

Do you ever feel restricted by just one world?  Would you rather have an entire universe of them, with a new blank canvas whenever you want one?

There is code in the inbox that allows you to do just that.  Visually, it’s like Squeak projects.  Although, there is no UI for this initial iteration, so you create and switch worlds via a simple API:

wm := WorldManager instance.
 
"Add a world"
wm createOrSwitchToWorldNamed: 'AnotherWorld'. 
 
"Return to the default world"
wm createOrSwitchToWorldNamed: 'Pharo'.
