Yes, because when you openInWorld, you do not create a window, you take Pharo window as container :) Ben On 25 Oct 2013, at 14:55, btc@openinworld.com wrote:

Basically what is done when you open a spec as world is that the background color changed, all the morph are closed, and the spec is specified to take all the space.

So to revert it, I think you *only* need to close the spec morph, set the background color to white, and voilà

Okay. So this works okay...

TabsExample new openWithSpec. [ (Delay forSeconds: 3) wait. SpecWindow allInstancesDo: [ :windowModel | windowModel delete ]. ] fork.

but this does not....

TabsExample new openWorldWithSpec. [ (Delay forSeconds: 3) wait. SpecWindow allInstancesDo: [ :windowModel | windowModel delete ]. ] fork.

However I finally managed to discover this works...

TabsExample new openWorldWithSpec. [ (Delay forSeconds: 3) wait. PanelMorph allInstancesDo: [ :pm | pm delete ]. ] fork.

Message #openWorldWithSpec: sets a Spec entity to take up the whole World. How can that be reverted? ...to set the World back to the state delivered with a virgin Pharo image?
