M - Morph
Object in Squeak that exists as a
programmable object on the screen. For example:
Morph new openInWorld
(highlight the magenta phrase with the mouse; rightclick; and choose 'do it') puts a new basic Morph (that looks like a blue square) in the current World one is in inside the Squeak environment. Although this new Morph is not special in any way, using its Halo it can be resized, moved, turned, inspected, debugged and attached code to. (You can remove any Morph you made by way of the x-Halo.)
One fine way to learn about Morph is to use an explorer:
Morph explore
Exploring Morph will show you that a Morph has many methods and that the blue square you can start by Morph new openInWorld is nearly as simple as it can get.
You can get lots of Morphs from Worldmenu-objects, and from Worldmenu-new morph...-from alphabetical list. They can all be explored, inspected, browsed and debugged from their debug halo.
