Let's say I have a new Morph:

m := Morph new.
m openInWorld.

How do I close / delete the Morph off?

m removeFromWorld.

CodePudding user response：

To remove a morph from the world, use the delete method.

m := Morph new.
m openInWorld.
...
m delete.

delete removes the morph from its parent morph (which is the world after openInWorld).
